We are encrypting file using the OpenPGP Writer pipeline component. According the to the client we sending files to; their public key contains "more then 1 sub lines".
The client says " It looks like your system thinks our key is expired…but we extended last year" . The same KEY is working when used from WS_FTP. Following is the decription error log provided by the client. Could you please advice?

C:\gnupg>gpg --homedir c:\gnupg --verbose -o XXX_test.txt -d xxxxxx_mar09*.PGP
gpg: public key is 15FB61A4
gpg: using secondary key 15FB61A4 instead of primary key EE4578E9
You need a passphrase to unlock the secret key for
user: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
gpg: using secondary key 15FB61A4 instead of primary key EE4578E9
2048-bit ELG-E key, ID 15FB61A4, created 2003-10-16 (main key ID EE4578E9)
gpg: NOTE: secret key 15FB61A4 expired at 10/14/08 10:57:14

It is likely that the document was encrypted with wrong (old) public key. If the public key file provided to you by your client contains several public keys, the document is encrypted with all of them.

Please download BizCrypto tools and check the actual contents of the client's public key file using the following command:
C:\> OpenPGPKeyTool.exe -display -pubfile public-key-file-name.pkr

Please set UseOldPackets property to true and UseNewFeatures to false and ask your client to decrypt the file created under these conditions.
