Hi,
I am using PGP 10.3.2 command line on Windows-2008 and my client is using PGP 10.3.2 command line on Linux.
We shared public keys and at both sides key imported and signed with our private keys.
I am able to decrypt the file sent by my client and don't see any issues. But when my client tries to decrypt the file sent by me, he is able to decrypt but see a message 3079:signing key invalid. I initially suspected that this could be due to my client did not sign my public key and/or not trusted in his key-ring after import. But this was not the case. My client imported my public key, signed and trusted using his private key but still encounters same message while decrypt.
Note: My client is using a trial version but I am using licensed version. ( I believe, this shouldn't be an issue)
I don't any issues with another client who is using PGP 10.3.2 command line on Windows-2008 but why the 3079 message prompts on Linux version of PGP.
