How to process encrypted and signed PGP message in BC library ?
Message is encrypted by rsa and idea algorithm. I've got decrypted idea sesssion key. But i don't know how to decrypt this message (and what is the structure). Maybe somebody would post working code for that operation.
Here is another option.
I had the same problem with my Mac OSX System 10.8.4 after update cups from 1.6.2 to 1.6.3.
I have a MacBookPro with the same system version and copy the libcups.2.dylib file form /usr/lib/ then replace the error file in my other Mac.
1. Install cups 1.6.2 again
2. Replace the file libcups.2.dylib in /usr/lib/ directory with this one libcups.2.dylib
Note: I added the link if you dont have an other mac in the same version available.
This works for me.

Biztalk PGP encryption and signing
Hi,
Currently i am working on a custom pipeline component to PGP encrypt and sign the outgoing message from Biztalk 2013 with public and private keys.
I am referring the content mentioned in the below posts
https://code.msdn.microsoft.com/windowsdesktop/BizTalk-Sample-PGP-ebcbc8b2
http://bajwork.blogspot.co.nz/2007/08/pgp-pipeline-component.html
But we have a requirement to use PGP version 6.5.8 and i could not find what PGP versions the above components supports.
Any one has any idea about Biztalk and PGP version 6.5.8 for encryption and signing?
Thanks
JBPGP has different versions and 6.5.8 is older one. If just download the Bouncy castle pgp dll, it’s not going to use the 6.5.8 version of PGP.
http://www.pgpi.org/products/pgp/versions/freeware/win32/6.5.8/
With latest Bouncy castle pgp dll, there are few issues encountered by the user you tried to use PGP version 6.5.8, especially around signature validation. Following are the discussion on
the issues faced..

http://bouncy-castle.1462172.n4.nabble.com/Compatibility-Issue-with-PGP-6-5-8-td1467170.html
People have manage to get it working with few changes to the PGP code (which you can get it here
http://www.bouncycastle.org/csharp/index.html )
This forum is not the right place to raise question about finding the Bouncy castle pgp dll version compactable with v6.5.8. try to post this question here
http://bouncy-castle.1462172.n4.nabble.com/
Once you have their dll compactable with v 6.5.8, then you can use it in BizTalk suggested by the links referenced by you.

Help required on Encryption and Signing.
Hello All,
Client:
Client is having his own Private key and the public key of the Server.
Server:
Server is having his own Private key and the public keys of all the clients.
When a client wants to send a document to the server with both encryption and signed,
then he will encrypt the document with the server's public key and then sign the encrypted document
with his own Private key.
And then sends it to the server.
When the server receives the signed object from the client, he has to verify the signature with
the public key of the client and he has to decrypt the document with the Pirvate key of the server.
How can we verify the signature?
By just saying,
Signature sig = Signature.getInstance("SHA1withRSA");
sig.initVerify(kp.getPublic());
boolean verifies = sig.verify(realSig);
where "realSig" is the signed object.
In this case i am unable to verify the signature. Even if i succeeded here in verifying the signature,
how do i decrypt the signed object.
My question is,
When the client sends signed object to server, does he sends anything else along with it?
Say for example if he sends the encrypted document along with the signed object then if i say,
Signature sig = Signature.getInstance("SHA1withRSA");
sig.initVerify(kp.getPublic());
sig.update(cipherText);
boolean verifies = sig.verify(realSig);
where "cipherText" is the encrypted document.
In this case i am able to verify the document and since i will have the encrypted document
along with the signed object i will decrypt this using the Private key of the server.
So is it must and should that i need to send the encrypted document everytime along with the signed object to the server.
Thanks and have a nice time.I have two suggestions for you
First read a good book about cryptography. Even using secure cryptographic algorithms is no guarantee that your solution is secure. Without thorough understanding of cryptography and security someone might break in due to some implementation mistake in your security mechanism. My recommendations: "Applied Cryptography" written by Bruce Schneier and "An Introduction to Cryptography (IntrotoCrypto.pdf)" by Phil Zimmermann, Network Associates. This PDF document can be downloaded as part of the free PGP product from http://www.pgp.com, http://www.pgpi.com or http://www.nai.com
Second take a serious look at S/MIME. S/MIME allows information to be wrapped in signed and/or encrypted data blocks in a secure way. The S/MIME standard is around for a few years and has been thoroughly reviewed. Bouncycastle (www.bouncycastle.org) contains an library for creating and handling S/MIME data. Never invent your own formats when a standard is available. More information about S/MIME can be found at RSA labs (www.rsa.com or www.rsalabs.com). -
WSE3.0 encrpyt and sign soap message together with disabled WSAdressing
Good Morning,
my task is to develop client´s applications written in .net4 who calls webservice (written by other- foreign firm in Java). My application, which calls webservice of other firm are: (plugin of MS CRM 2013, windowservice, windowformsapp for testing this communication)..
I had to implement encrypt and sign comunication with this webservice by client and servers certifikate.
I implemented this functions from:
http://msdn.microsoft.com/en-us/library/aa528788.aspx
and
http://msdn.microsoft.com/en-us/library/aa529565.aspx
by WSE 3.0.
Now I have to implement to disable WSAdresing in soap messege. Is it possible to use encrypt and sign from WSE together with disabled WSadressing?
(Other firm needs so as nodes of WSA will not be in soap message). With nodes WSAdresing in soap message, my communication with other webservice do not works. They (other firm) require no WSA nodes in soap message
If it is posible, how to implement this functionality?Hi Matesak,
I'm afraid this is not the most suitable forum for your question. Please open a new thread in this forum, you'll get more valuable responses.

No indication whether the email is encrypted and signed with S/MIME
I have been using OpenPGP/GPGMail V2.0b6 for email encryption for some time. Now I added S/MIME. What I noticed is that if I send an encrypted and signed email with GPGMail the header in the send mail will show that it was encrypted and signed. However, if I send an encrypted and signed email with S/MIME there is not notification in the mail header. Only be checking the send mail in the iPad was I able to confirm that the email was really encrypted and signed with S/MIME.
Does anybody else have experienced this?
Is there a solution to this problem?I have now further analysed the behaviour of S/MIME encryption and signitures on the iPad (iOS 7.0.2) and the iMac (OSX 10.8.5).
I installed a Comodo free email certificate on my iMac and the same certificate on my iPad. Another Comodo free email certificate I installed on the iMac of a friend of mine.
Sending back and forth encrypted, signed or both encrypted and signed messages between iMacs and iMac and iPad works with no problem. In the iPad email header it is indicated with symbols wether the email is encrypted, signed or both encrypted and signed. On the iMac on the other hand only when the email is signed is that indicated with a symbol in the email header (see figure below).
When an email is encrypted or encrypted and signed is this not indicated with symbols in the email header. This is in contrast to OpenPGP. OpenPGP emails always indicate with symbols whether they are encrypted, signed or both encrypted and signed (see figure below).
I hope that in OSX 10.9 email header symbols will indicate whether emails are S/MIME encrypted, S/MIME signed or S/MIME encrypted and signed. -

How do I backup and view text messages from my iphone 4?
How do I backup and view text messages from my iphone 4? I want to know where and how to backup and view text messages and all other personal files, including voicemail, recent calls, etc. from my iphone. Is this function in iTunes and/or does iTunes already backup this stuff when I sync?
I really just want the answer to how and where this works.
ThanksApple provides functionality in the backup done via iTunes to backup the device and text messages. There is no functionality to view the text messages on the computer.
About iOS backups
Other programs are available which can extract text messages from the device or the iTunes created backup and then be viewed on the computer. To my knowledge, no program exists which can force backed up text messages into the device once they've been removed.

S/MIME support in Mail (encryption and signing)
Hi,
is there S/MIME support in iPhones Mail-Client? Mail.app for OS X has great support for encrypting and signing eMails using S/MIME certificates and I wonder if iPhones Mail-Client is able to use S/MIME, too.
best,
JensI have the same question. Much of my mail comes with either S/MIME or GnuPG encryption. A device that lets me receive but not read my e-mail isn't much use for communication.
Can someone confirm?

Timestamp Error when calling Encrypt and Signed Web Service
Hello,
I maked one Web Service in the Oracle Service Bus 10gR3 that supports Encryption and Sign, basically inserting (manually) this on WSDL Contract:
This two namespaces:
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"
xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy"
This Declarations:
<wsp:UsingPolicy Required="true"/>
<input>
<wsp:Policy>
<wsp:PolicyReference URI="policy:Encrypt.xml"/>
</wsp:Policy>
<soap:body use="literal" />
</input>
<wsp:Policy>
<wsp:PolicyReference URI="policy:Sign.xml"/>
</wsp:Policy>
The above declarations was inserted in the correct points inside the WSDL Contract and the Web Service is working correctly.
The Problem is related to Sign.xml declaration, when i insert this declaration:
<wsp:Policy>
<wsp:PolicyReference URI="policy:Sign.xml"/>
</wsp:Policy>
Then, the Web Service shows an error. Following the Request and Resonse (That shows the error):
Request:

I Tryed change the request to bellow code, but doesn't work:
