Seperate Session Key and Encrypted Data

[Koszta Dániel]

You can use the --show-session-key and --override-session-key option for
gpg.

$ gpg --encrypt <<< "Test Message" > msg
$ gpg --decrypt --show-session-key msg
$ gpg --decrypt --override-session-key 'the_session_key_gpg_gave_you'

Note that you do not need your private key for the last operation.

However, I'm not sure of the security implications of this. From the gpg
manual:
