Possible with clients that support easy(ish) passing of key-data handling to pinentry. Also, I should have added -a flag to the command so that output is ASCII, e.g. `gpg -o encrypted -ac cleartext` -- Regards, A Current version is 8.0.18 | 'Using TBUDL' information: http://www.silverstones.com/thebat/TBUDLInfo.html
Re[2]: encrypting messages
Hello Christopher, Thank you for the well-constructed and informative message, I just wanted to add one small point to the below: >> What I would like to be able to do is send password-protected >> messages that can only be opened by the receiving party who has the >> password. Is that what this process does? > Neither S/MIME encryption nor Open PGP encryption password protect a > message. (Encryption doesn't require password protection, and > password protection doesn't imply encryption.) > S/MIME and Open PGP use asymmetric cryptography (public & private > keys). There is no "shared secret" or password between the two of you. > A shared password would be a use of symmetric cryptography. I'm not > aware of an email encryption standard that uses symmetric cryptography. It is *technically* possible to use GPG in symmetric mode for messaging purposes. ``` $ echo "Hello World" > cleartext $ gpg -o encrypted -c cleartext ``` ...Then one needs to wrap the routine above into something palatable for e-mail usage. I could imagine doing it with (neo)mutt et al., but not with TheBat. -- Regards, A Current version is 8.0.18 | 'Using TBUDL' information: http://www.silverstones.com/thebat/TBUDLInfo.html
