GPG Decrypt errors

hello experts,

new to PGP and GPG, i have cleint that we PGP encrypt and add a signature and we are still getting an "invalid signature " while decrypting
 the finger print ID matches and sent the file Ascii Armor on/off
signed and unsigned still no progress
question can this be decrypted without the signature added? i was told yes and weather we add or don't add the signature should not make a difference the file still should decrypt
please help

thanks for the response!
Key XXXXXXXXX was in the clients log trying to decrypt a file i encrypted using thier public key
i verified that Key XXXXXXX  matched the finger print when i received the clients public key with PGP desktop
i can try redo of the key exchange unfortunately done it twice thinking that was the problem

question even if the file is encrypted and not signed it still should decrypt for the client correct?


Do you see other party's public key in both ends?
You need to make it "Ultimately trusted" or "trusted" depending on environment, or just sign it using your private key.
I suggest you install gpgme on windows and import gpg stuff from AIX - maybe visual appearance resembles PGP and you can fix all in instant...


i think i found out the issues
we have two boxes for PGP a  test and prod box someone signed using the test box and sent our prod pub key....D'oh!

i'll let you know what we found out

Your help has saved me hundreds of hours of internet surfing.

Only one private key is able to decrypt encrypted file.

we have the clients public key and were sucessful in encrypting and decrypting, main problem was the signature from my end,
seams like some sort of compatiblity issues with AIX and our z /OS and GPG and our Megacrypt PGP respectively
thanks gheist for your insight
i'm still testing and working with our PGP vendor so i'll keep you up to date.
