Hi Team,

We have setup the entire GnuPG software along with the keys in our Linux
server. We are able to encrypt our message and send it to our vendor. even our
vendor is able to decrypt it at their end. But we are not able to decrypt the
message sent by the vendor to us.

We tried decrypting the error from OS level . this is the error we got -

root@ldxsap23: ~/.gnupg

gpg -v -v --decrypt /basis/home/sh34191/PYRESULT_KS_20160728192815.csv.pgp

gpg: armor: BEGIN PGP MESSAGE
