Timestamp Without Signature

I have created a form using LiveCycle Designer with a button formatted to email me the completed form in PDF format. I would like to have the form timestamped upon submission but without requiring the other individual to sign it. Does anyone know if this is possible and if so, how it would be done?

Thanks for pointing me in the right direction on this. What I ended up doing was adding javascript to my existing submit by email button. This is not the submit by email button but just a regular button where I changed the control type to submit. Under the first event tag, I added the following second event:
<
event activity="mouseDown" name="event__mouseDown"><
script contentType="application/x-javascript">var rightNow = new Date();form1.subform1.TextField8.rawValue = (rightNow.toDateString()).substring(4,(rightNow.toDateString()).length) + " " + (rightNow.toTimeString()).substring(0,8);
</
script></
event>
This filled in the text field I created with the current time from the pc as a static value, creating the timestamp I needed. Thanks again for your help!

How can I made a text box to accept initials or signature without signature field?

I create forms for my clients using Adobe Pro 9. Due to the potential lack of computer literacy of their customers, my clients would like to make a field that would accept an initial or a signature without the steps needed for a digital signature.
The steps would be 1) customer opens form with Acrobat Reader; 2) click on Fill & Sign Tools, then create the initials to use; 3) drag the initials to the textbox. At this point the size of the initials would correspond with the size of the text box.
I have experimented with having the text box property Appearance-Text-Font size: Auto. However when I opened the PDF in reader, I would have to resize the signature block.

Hi bluecraby2k,
If I understand your question, you don't want to use the Signature form field, because your client feels that might be too complicated for some users. Is that correct?
The Place Signature option on the Fill & Sign tab allows you to drag a signature onto the page, but not directly into a text form field. I don't believe there's a one-to-one relationship between the form field and the Place Signature option.
I'm going to move this discussion to the Forms forum, so the experts who visit that forum can chime in.
Best,
Sara

Add timestamp to signature

how can i add time stamp to digital signature (not pdf file. i just sign a string)

Your question is the equivalent of asking how to add a date/timestamp to a piece of paper you just signed with your pen. The answer is, write it wherever you want to write it.
A digital signature is merely cryptographically verifiable data about another block of data (the document), i.e. it certifies the document's origin (the signer) and, in the digital case, the fact that the document hasn't been altered. Signatures have nothing to do with dates, though in the real world dates are often carried along with signatures. Neither requires the other.
Arguably the best solution for you is to make the date part of the document you sign. It thus becomes verifiable, too. Beyond that, you are entirely free to devise a scheme as to how to format the date and where to place it in the document.

Timestamp and signature problems

Hello, everybody!
I have a problem when attaching a timestamp to a signature using the BouncyCastle provider.
I have read the [RFC 3161|http://www.ietf.org/rfc/rfc3161.txt] and in chapter 2.4.1 it states that the messageImprint contained in the request "SHOULD contain the hash of the datum to be time-stamped."
Also, in the appendix A of the same RFC, it's stated: "The value of messageImprint field within TimeStampToken shall be a hash of the value of signature field within SignerInfo for the signedData being time-stamped."
My problem is as follows:
I'm creating a request generator, using TimeStampRequestGenerator class in the org.bouncycastle.tsp package of the BouncyCastle provider. Then the request is created using the generate method of the TimeStampRequestGenerator object
TimeStampRequestGenerator reqGen = new TimeStampRequestGenerator();
reqGen.setCertReq (true);
TimeStampRequest request = reqGen.generate(TSPAlgorithms.SHA1, hash, BigInteger.valueOf(100));Please, be aware that the hash variable is generic. But what value must this variable have? The value of the a hash function for the unsigned data or the value of a hash function for the signature field in the SignerInfo? What is the right way to build the request?
The request should be build using the hash of the unsigned data? Then, after generating the pkcs7 file with the timestamped attached as an unsigned attribute, when a verification is performed, should I verify that the value in the messageImprint has the same value with the hash of the signature field in the SignerInfo? If so, it means I'm doingsomething wrong,because those values cannot be equal at all.
Or the request should be built using the hash of the signature. And when the verification is performed, the messageImprint will contain the correct value, as stated in the Appendix A of the RFC3161?
So my problem is what value must be passed for the hash when building the request?
Any help qould be appreciated.
Thank you!

problem solved
I had interpreting in the wrong way the RFC3161 that states that if adding the timestamp to a signature in a pkcs7 file the hash that needs to be sent to the TSA must be the hash of the signature field in the SignerInfo of the data.
Which is correct if I stay a little bit to think because the timestamp is for the signature, not for the unsigned data.
So, when creating the request for the TSA, the hash has to be the the hash for the signature.

Timestamp digital signature

Hi,
We have implemented the digital signature that is triggered by setting a specify document status. We see however that the timestamp of the digital signature differs for other changes in document attributes. The timestamp for the digital signature is set by the Timezone-time. Both times can be looked up in the menu System-Status. The timestamp for the other changes are defined by the System time. Does anybody know how to align the two?

Systemtime and solution manager timezone were not in sync.

Timestamp without time component

Hallo,
Please help.
I use JDeveloper 10.1.3.2
I have a table with date column.
EO on basis of this table with Timestamp attribute
with the following code in Entity Object Class in order to put the default system date in my field:
public Timestamp getDatum() {
if ( getAttributeInternal(DATUM) == null) {
setDatum(new oracle.jbo.domain.Timestamp(new java.sql.Timestamp( System.currentTimeMillis() )));
return (Timestamp) getAttributeInternal(DATUM);
Application definition with DateTimeField (as display type) item.
When entering the new record I see my field with system date including time component.
But after commit the transaction I see in database the date value of my field withoud time component.
Thanks,
Anna

My own mistake. Trigger in database that truncated my date-field. Stupid me!

Timestamp server authentication issues

I'm using Adobe Reader XI and when using http timeStamp server that requires basic authentication is always tried without the needed BasicAuth field set.
That's the request adobe send
POST /cdie/HttpService HTTP/1.1
accept: */*
content-type: application/timestamp-query
content-length: 69
character-encoding: binary
user-agent: PPKHandler
connection: Keep-Alive
cache-control: no-cache
The reply is a simply HTTP/1.1 401 Unauthorized because the request hasn't the authentication field.
I've tried using Windows and Macintosh
Why didn't send the basic authentication?

What exactly are you trying to do? Are you signing a PDF with a certificate-based digital signature? You cannot sign in Adobe Reader unless your PDF is Reader-extended with permissions to sign.
If your PDF is Reader-extended or you're signing with Acrobat Pro, and you want your signature to be timestamped you need to set up the timestamp server in Acrobat/Reader. If your timestamp server requires authentication, you need to provide authentication information in the Acrobat's timestamp server setup. Some signing credentials (Digital IDs) have timestamp server information embedded in the certificate. In this case Acrobat will use this timestamp server to timestamp the signature and you do not need to set up this timestamp in Acrobat's timestamp servers list unless this timestamp server requires authentication. If it requires authentication, you need to set it up in Acrobat/Reader providing authentication info.
You should never access timestamp server if you just open a signed PDF.

Digital Signature validation with expired TSA certificate

Hi,
I used Adobe Acrobat 8.2 to sign a PDF document with "certifying signature" (note: not approval signature) using a self-signed certificate and a remote TSA. I did NOT embed long term validation information as described here
http://help.adobe.com/en_US/Acrobat/9.0/Standard/WS934c23d7cc8877da1172e0811fde233c98-8000 .html
The TSA certificate expired on a few days ago and now I am getting "not time valid" error on the TSA certificate (see attached mage)
The signature validates fine since I get the ribbon icon at the top for certified document as described here:
http://www.adobe.com/devnet/acrobat/pdfs/validation_cheat_sheet.pdf
The problem is that I don't get the Clock symbol on the timestamp because Signature Properties says
"signature is timestamped but timestamp could not be verified"
The trust settings for all certificates are fine.
I also changed "Verification Time" in Edit-->Security-->Advanced preferences to be "Time signature was created".
I validated the signature using Adobe Reader 8 as well as 9 and got the same error.
What am I doing or expecting that is wrong ?
Appreciate any help!

Thanks. That worked! Back in the sunshine again
The message is as seen below : "signature is timestamped but TS has expired"
I am assuming this is the right message. If not, do respond.

Message mapping with signature changed

Hello,
I have a mapping whose incoming and outgoing message has the same message type, let's say the message type for both in and out message is *MT_Material *. The mapping basically copy all data from in message to out message, however, the out message is only created based on certain condition. Therefore I changed the signature to define the Occurance of the out message as 0..1 while the in message has occurance of 1.
Things work fine, out message only contains data when the condition is fullfilled. However the mapping program expects incoming message like;
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
   <ns0:Message1>
      <ns1:MT_Material xmlns:ns1="http://mynamespace">
         <MatNo>123345</MatNo>
         <MatText>
            <Language>en</Language>
            <Text>esx</Text>
         </MatText>
         <MatText>
            <Language>fr</Language>
            <Text>esxfr</Text>
         </MatText>
      </ns1:MT_Material>
   </ns0:Message1>
</ns0:Messages>
Note the xml tags in bold are needed because of the signature change (occurance change). However the outbound interface is based on the message type of MT_Material, thus the sender will NOT send the xml tags in bold, rather following message is sent:
<?xml version="1.0" encoding="UTF-8"?>
      <ns0:MT_Material xmlns:ns1="http://mynamespace">
         <MatNo>123345</MatNo>
         <MatText>
            <Language>en</Language>
            <Text>esx</Text>
         </MatText>
         <MatText>
            <Language>fr</Language>
            <Text>esxfr</Text>
         </MatText>
      </ns0:MT_Material>
Message in this format is NOT expected by the mapping program with changed signature, thus mapping is does NOT result in the right result.
So what should I do with it? looks like change signature doesn't make any sense because it expects different outbound message format as the one without signature changed.
Basically mapping is PI internal stuff, the sender should not be aware of it, thus sender should just send a message based on the message interface which is based on MT_Material.
what do you thnk of this?
Any

Hi Jayson
You are correct to some extent we should not force the vendor to send a tag to satisfy middleware. But if the tag is required for the business process what can be done other than forcing as a rule to vendor
As PI is a XML based tool where XML is tied to a XSD all messages need to follow XSD. Now in your requirement we need to meet the condition for generating the output. Being a middle ware PI is not meant for holding the messages or used as an end point for some communication. It works on two engines and we need to pass IS without error. Mapping will work at IS and if it failed its an error but we have to satisfy condition.
I have faced similar requirement to yours. I had routed the messages through email to vendor when no output need to be generated as they were incorrect and doesn't follow business rule of the process.
We can check with Xpath or either some the way we discussed above in case condition is not met
Thanks

Using TRUNC in timestamps

Sir,
As you know we were using TRUNC function in DATE datatype. But I want to use it with TIMESTAMP datatypes. For example:
select trunc(systimestamp,'hh24:mi:ss') from dual;
The main idea to get some part of given timestamp without using type conversions (i.e. TO_CHAR).
Note that this is useful when you want to ADD or Subtract the time side from timestamp with interval values and comparing them to another timestamps fields or values.
Thank you in advance.

Trunc is not working in 9i

Document signature with date/time received stamp

Does anyone know if you can combine the feature of a date/time received stamp with the signature of the person who received it?
Regards,
Sean

Hi Sean,
The way a time stamp works is that it's a signature over the document signature, kind of like when a notary public signs a document. They (the notary) are not verifying the accuracy of the document, only that you signed it and when you signed it.
Generally (can you sense that this is going to get more complicated then it should be ), a time stamp is created (by a trusted third party) at signing time to prove that the signature existed a a particular point in time. If you timestamp your signature at signing time it cannot be time stamped again by the receiving party. If the receiving party wants to add a timestamp they need to sign the document themselves. An example of this is the patent office. It doesn't matter to them what time you signed the patent application, but rather when they received it. They add their own timestamp to show what time the application was received by signing the document a second time.
Now just to confuse things a bit, starting with Acrobat 9.1.0, if the signature was not time stamped at signing time, it has the ability to add a timestamp post signing. You can add the timestamp by opening the Signature Panel, right mouse click on the signature, and select Add Verification Information from the pop-up menu. You must have a timestamp server configured in the Security Settings console and the Include signature's revocation status when signing preference selected in order for this feature to be available, and the signature must be valid. You cannot add a timestamp post signing over an invalid signature.
I hope this helps,
Steve

Timestamp question in RS02

Hi experts,
If I use the transaction RS02 how can I know the timestamp that are using..? because I see that in our development system the screen have Timestamp (UTC).... but if I access the QA environment I see that in that transaction in the screen have 'Timestamp' without indicating me if is UTC or what timestamp....
How can I check what Timestamp I'm using in that transaction in the QA environment??
Thanks a lot four ur help!!

Hi,
1.For Time Stamp ...try table ROOSPRMSC it gives timestsamp details.
In the se11 by choosing the menu path utilities->Runtime object->Display you can see the time stamp.
2.In RSA7(Delta Queue) would help you.

Timestamp error in j2se5.0

I am working on opensource project and i am buiding it from source.
it will work on jdk1.5 and orackle 10g, when i am buindling, i am getting error of timestamp as:
"reference to Timestamp is ambiguous, both class java.sql.Timestamp in java.sql a
nd class java.security.Timestamp in java.security match
[javac] Timestamp ConvDate, String RateType, int AD_Client_ID, i
nt AD_Org_ID)"
first I tried with jdk5.0 as in the sun site in compatbility it is given timestamp function is removedin jdk5.0, and j2se5.0 i shaving that function.so I tried with it but I am getting the same error.
How can I include Timestamp function in j2se, so that i can over come this problem.plz help me out.

This has nothgin to do with Java 1.5 and not with Timestamp and not with compatibility and not with any removal. This is simple namespace behaviour in your source code. You have a class that imports java.sql.Timestamp and java.security.Timestamp (e.g. if you do a import java.security.*). If you now use the class Timestamp how should Java know which one to use? You need to use it with full package reference in your method where you use it:
java.sql.Timestamp ts = new java.sql.Timestamp(System.currentMillis());Perhaps you don't need java.security.Timestamp but other classes from java.security. So don't import the whole package (import java.security.*) but onle the classes you really need. Then you can use Timestamp without the package reference in your method.

ORA-04062: Signature of package ... has been changed

We've had a repeated situation where an unaltered package spec has been recompiled, which was in excess since only the package body has incurred a change. But, our Oracle Forms application throws the ORA-04062 error nonetheless when trying to access the package.
I originally assumed that the spec had actually changed when this error came up, and didn't do any additional research. But this time around, I checked, and only the package body is different. The spec, though compiled, is identical to the version that was there prior.
What makes up the "signature" and why does Forms keep thinking that a recompile equates to a signature change?

Sys_extract_utc, sysdate and cast to timestamp

I have a question about sys_extract_utc.
According to this document:
http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions167.htm
SYS_EXTRACT_UTC function entry is a datetime_with_timezone.
so... running this in my system:
1) select TO_CHAR(SYSDATE, 'YYYY-MM-DD HH24:MI') as mysysdate from dual;
MYSYSDATE
2013-05-14 20:27
2) select TO_CHAR(systimestamp, 'YYYY-MM-DD HH24:MI TZR') as mysystimestamp from dual;
MYSYSTIMESTAMP
2013-05-14 20:27 +03:00
3) select TO_CHAR((cast (sysdate as timestamp)), 'YYYY-MM-DD HH24:MI TZR') as cast_sysdate_timestamp from dual;
CAST_SYSDATE_TIMESTAMP
2013-05-14 20:17 +00:00
4) select TO_CHAR(sys_extract_utc(cast (sysdate as timestamp)), 'YYYY-MM-DD HH24:MI TZR') as utc_time from dual;
UTC_TIME
2013-05-14 17:27 +00:00
Questions:
How is it possible to have the query 4) correct... if the cast of sysdate to timestamp in 3) does not have the correct timezone has you can see in query 3) !?
Where does sys_extract_utc collects the information, in order to make query 4) correct?
Edited by: PauloSMO on 14/Mai/2013 10:37

The reason you are seeing cast (sysdate as timestamp) with a time zone of +00:00 is because you cast it to a timestamp without time zone. When you displayed it with a TZR it gave the +00:00 because there is no zone - it's a zone-less timestamp. SYS_EXTRACT_UTC requires a timestamp with time zone as its parameter so it casts the timestamp to timestamp with time zone which puts it into the local time zone +3. The Oracle 11.2 documentation of SYS_EXTRACT_UTC has added
If a time zone is not specified, the time is associated with the database time zone.The output of SYS_EXTRACT_UTC appears to be TIMESTAMP (no time zone).
You should have cast(sysdate as timestamp with time zone) to get the equivalent of systimestamp:
On my system (running GMT + 10)
1. select cast(sysdate as timestamp) from dual;
16-May-2013 09:52:56.00 -- that's using my NLS_TIMESTAMP_FORMAT
2. select cast(sysdate as timestamp with time zone) from dual;
16-MAY-13 09.52.50.000000 AM +10:00 -- that's using my NLS_TIMESTAMP_TZ_FORMAT format
3. select to_char(cast(sysdate as timestamp), 'YYYY-MM-DD HH24:MI TZR') from dual;
2013-05-16 09:59 +00:00 -- the +00:00 is meaningless - a timestamp doesn't have a time zone.
4. select to_char(cast(sysdate as timestamp with time zone), 'YYYY-MM-DD HH24:MI TZR') from dual;
2013-05-16 09:59 +10:00 -- +10:00 is my real time zone.
5. select sys_extract_utc(cast(sysdate as timestamp with time zone)) from dual;
16-May-2013 00:05:43.00 -- Incidentally, notice the lack of a time zone here - it's a TIMESTAMP without time zone, using my NLS_TIMESTAMP_FORMATregards,
