Digital Signature error message

I am using Windows 7 64bit, Adobe Acrobat XI and have imported my personal digital signature certificate as well as the certificate from the signing authority. They both show in preferences, but mine has a yellow triangle with an exclamation point before it. When I try to sign a pdf document I get the following error message: "You do not have any digital IDs suitable for signing this document". Anyone know what the missing pieces are? Thanks

Investigating the issue there is indeed a “signing private key lifetime” that Adobe seems to be using. This is a setting on our vendor site and is set to 70% of the Public Key Lifetime (which is 5 years). As a result – despite the fact the key can be used to sign messages it would appear that signing documents is set to 3 years and 6 months by virtue of this setting.

ITunes 9 download - invalid digital signature error with Windows 7 Ultimate

Since I have upgraded to Windows 7 Ultimate when I try and download the latest version of iTunes 9 I get Invalid Digital Signature error message. I've tried downloading with IE8, Opera and Firefox.
Help please!!

Perfect, thanks.
I see that one's got an SPI firewall:

By way of experiment, try disabling the firewall and doing another iTunes download. Are you able to get a working installer this time?

AIP-51083: General failure creating S/MIME digital signature: Error

I know you guys did answer to this kind of question in several threads. But my case is bit different. Please try to help me to resolve this issue.
OS: AIX 5.3
B2B: 10.1.2.2 (No Additions)
I did encrypt the message using certificates (Host & Trading Partner) and send to Trading Partner and got the confirmation. So assuming there is no issue with wallet and certificates.
But I am not able to sing the same message using same certificates.
(I don’t have any issue with Host certificate, I can use it for host sing but I have issue with Trading Partner certificate)
Here the error message. I really appreciate your help.

Hi Anuj,
Thanks for your good reply.
I was doing same thing which you mentioned (Thats the reason encryption is working with same certificates, so there is no issue with wallet and certificates).
in my log (debug mode) I did find some thing is interesting
From the log,
<MSG_TEXT>oracle.tip.adapter.b2b.packaging.SmimeSecureMessaging:SmimeSecureMessaging: sign alternateWrl: /oraaiad/B2BHome/Apache/Apache/conf/ssl.wlt/default/wallet1</MSG_TEXT>
Log is looking for alternateWrl "/*default/wallet1*"
But my wallet location which I mentioned in tip.props /oraaiad/B2BHome/Apache/Apache/conf/ssl.wlt/*default/wallet.txt*
I know there is no location called "*wallet1*" thats the reason why it's throwing null pointer. But my questions is, why it's looking for alternateWrl? Here some of debug log.

InfoPath Digital Signature Error

In the InfoPath browser form, when I digitally sign the form, I get the following message:
There is a problem with this signature.
By clicking on Show Details, it says:
Untrusted signature - The trust chain cannot be verified
Any ideas how to resolve this error?

Hi Nikhil,
According to your description, my understanding is that you got an error when you used the InfoPath form with digital signatures.
For this issue, it seems to be about the InfoPath form template certificate, you need to create and export it, then import to SharePoint server.
More information, you can refer to the two links:

Many thanks in advance.

I've had this problem for awhile in Windows XP SP3. Last night, the simplest thing occurred to me...here's what I did (and I'm telling because it worked).
1. Clicked on Start
2. Clicked on Control Panel
3. Chose Add/Remove Programs
4. Found Apple Software Updater and clicked Remove, then responded Yes
5. Went to apple.com and clicked on Support, and then Downloads
6. Downloaded the latest version of Safari ONLY
7. Installed Safari (knowing it would install the latest version of Apple Software Update)
8. AFTER the installation was complete, I clicked again on Start, then All Programs
9. then, clicked on Apple Software Update

How to create a digital signature error

Hello,
hope i do my post in the right forum (if not i'd be grateful if it could be displaced to the correct forum). I've to do create some incidents to have a look at the output of Security Audit Log (Transaction sm20).
I want to create a digital signature error (SAL Identifier AUV) and i've no clue how i could get it done. First I thought about an invalid single sign on ticket but apart from I would have no clue about how to create such, I don't know if that's a way to make the error, mentioned above, occur.
Maybe you could give me a hint or you have an idea how I could get that done!?
Thanks in advance
Tobias

Adobe Reader Touch (Windows Store app with "modern" UI) does not support any types of signatures yet.
Digital Signatures with certificates
Electronic Signatures (that are legally enforceable)
Signature annotations (hand-writing annotations which may not be secure and legally enforceable)
Adobe Reader XI (traditional desktop app with classic UI) supports #1 and #3.
Adobe EchoSign supports #2.
Adobe Reader for iOS/Android supports #3.

Digital signature error while confirming maintenance order

hi all,
while i try to confirm maintenance order i m getting following error.
"Unable to find strategy information about strategy
Message no. SIG403
Diagnosis
Signature strategy has been allocated to the function you selected. However, signature strategy has not been defined in the system. The individual signatures may be missing.
The system does not carry out the function."
I checked in SPRO but couldn't find any configuration related to digital signature..
Please suggest how to overcome this issue..
Regards,
Amit kushwaha

Hi Pete,
Digital signature is activated for the function IW41. AS per the SAP help i should maintain configuration in

I checked SPRO menu paths to locate above mentioned path. but it is not there
Please suggest !

Signature 171 Digital Signature Error

When I install signature 171 to IDSM2's using VMS 2.3 I get: An error occurred while running the update script on the sensor named IDS-C1-B. Detail = An error occurred at the sensor during the update, sensor message = idsPackageMgr: digital signature of the update file was not valid, use CCO to replace corrupted file
The update of the VMS management center and security monitor worked OK. Does anyone know it this signature zip file is really corrupt?
I re-downloaded and replaced the file in VMS, but still got the same message.

Upgrading a sensor via VMS is part of our standard testing procedure for a new signature update and it passed the test!
Unfortunately, for some reasons, the checksum of the file published on Cisco.com doesn't match the checksum of the file we have tested.
My apologies for any inconvenience it could have caused, we are working to have this fixed asap!
I'll post again once this has been done.

Digital Signature Error: Parameter and size limit

I am getting the following error message when I am trying to digitally sign any pdf:
Creation of this signature could not be completed.
Size limit error
Internal error: a function parameter had an incorrect value.
I have browsed this forum, but could not find anything similar described. I have tried deleting and recreating my digital signature, etc, without any differences. I had used dig sig before on this pc. I have Acrobat 8.2.3.
Anyone able to help?
S.

Okay, I think you are on to something.
When I go into Security Settings, there are two Windows Digital IDs listed. Both are in my name, and both are Issued by Aliant ICN Authentication CA (Aliant is my employer). They have expiry dates of later this year.
Neither of them are checked with any indication of a Usage.
When I look at Certificate Details, they both indicated "The Selected Certifcate Path has errors: unexpected errors." Under Trust, "This certificate is not trusted".
I could not see Storage Mechanism anywhere.

Verifying a Digital Signature using message digest

Hi, i am new to java.
I have a Digitally signed document, i wanna verify this signed document against the original one.
i got the idea from this link:
http://help.sap.com/saphelp_45b/helpdata/en/8d/517619da7d11d1a5ab0000e835363f/content.htm
i signed a pdf doc with my SmartCard. the third party signing tool passed me the PKCS7 digital signature and i stored it in database. the problem arose when i retrieved this digital signature from DB and verified against the original doc using the message digest method. the base64 result strings are always not equal.
I am sure about this:
-the retrieved digital signature was GOOD.
-the original doc was GOOD.
but why i can't get the same 2 message digests? can somebody please help?
below is part of my code:
while (rsetDs.next())
     InputStream DSName2 = rsetDs.getBinaryStream(1);
     ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
     byte[] myByte = Base64.decode(byteStream.toString());
     ByteArrayInputStream newStream = new ByteArrayInputStream(myByte);
     CertificateFactory cf = CertificateFactory.getInstance("X.509");
     Collection c = cf.generateCertificates(newStream2);
     Iterator i = c.iterator();
     while (i.hasNext())
          Certificate cert = (Certificate)i.next();
          X509Certificate cert1 = (X509Certificate)cert;
          try
               java.security.MessageDigest md = java.security.MessageDigest.getInstance("MD5");
               /*=============DB MD (BEGIN)==================*/
               byte [] pubkeyByte = cert1.getPublicKey().getEncoded();
               md.update(myByte);
               md.update(pubkeyByte);
               byte[] raw = md.digest();
               String db_md = Base64.encode(raw);
               /*============DB MD (end)============*/
               /*=============PDF MD (BEGIN)==================*/
               DataInputStream m_disFile = new DataInputStream(new FileInputStream("C:\\" + "original_doc.pdf"));
               int m_iNum = m_disFile.available();
               byte[] msgBytes = new byte[m_iNum];
               m_iNum = m_disFile.read(msgBytes, 0, m_iNum);
               md.update(msgBytes);
               byte[] digestMd = md.digest();
               md.reset();
               String pdf_md = Base64.encode(digestMd);
               /*=============PDF MD (END)==================*/
..thanks in advance.

PKCS#7 SignedData objects are far more complex then it looks like you are taking them. First the PKCS#7 SignedData object will contain the OID for the message digest algorithm used and for the encryption algorithm used. From the looks of your code you are simply assuming MD5.
It also contains all of the data that was signed which is typically much more than just the document. It also of course contains the public keys and signatures which singed the document. In your case it will probably only have one public certificate and one signature.
Also note that a signature is an encrypted hash. Looking at your code I do not see you use encryption at all or rather for verification decryption.
Here is the basic process a signature takes.
MessageDigest md = MessageDigest.getInstance(algOID);
byte[] digest = md.digest(message.getBytes(charEncoding));
Cipher c = Cipher.getInstance("RSA/2/PKCS1Padding");
c.init(Cipher.ENCRYPT_MODE, priKey);
byte[] signature = c.doFinal(digest);Note that the resulting byte array is not the message digest but the encrypted message digest. You must use the corresponding public key to decrypt the signature to get the message digest value. It is because the trusted public key can decrypt the correct message digest that we know it was encrypted by the holder of the private key. It is because the decrypted message digest value is equal to my computed message digest value that we know the document has not be altered...
Now PKCS#7 SignedData does not take the message digest of the document, in your case your PDF. It creates a message digest on an ASN.1 object which includes the bytes of your document plus a bunch of meta data.
For more info on the exact format of a PKCS#7 signature file check out
http://www.rsasecurity.com/rsalabs/pkcs/pkcs-7/index.html
Look through this doucment for SignedData as a starting place and follow through all of the sub objects that make up a SignedData object. This will give you an idea of what is involved.

InfoPath 2010 digital signature error in SharePoint 2010 - Revocation Status cannot be verified

Here is the issue: I have two servers, one a Test and one a Production. The Test server allows me to digitally sign the document and shows it correctly. In the Production environment, I used the same form and browser and it gives me the error: 'Revocation
Status cannot be verified' when digitally signing.
The InfoPath form is web-enabled and works perfectly on the Test side.
The browser is the same, updates are one week apart...is there anything I am missing????

Hello,
Do you have the same certificate in prod server Trusted Root Certificate Authorities? If not then please add it.

Digital Signature Error

Hi All,
We are implementing digital signature for originals in DIR using secure,store and foward approach. The installation is pretty much ok,. However, we are getting SSF_API_NO_SECTK error. What could be the possible reason? We are using SAPSECULIB as the security provider,

The error indicates that the security product is not installed correctly. Make sure that SSF_LIBRARY_PATH (or ssf/ssfapi_lib ) is set correctly.Set the trace level to 1 and check the contents of the trace file dev_ssf.
