Is there a GPG encryption mode that does not requires to have a specific public key stored and requires only one passphrase to be decrypted?
It would make the decryption possible on any machine if the passphrase is known.
I don't want to use
openssl since I cannot do in place encryption easily.
cat file | gpg -e > file
is encrypting the file.
cat file | openssl enc -des3 > file
produces an empty file.
