Gnupg-users Digest, Vol 220, Issue 11

[Ryan McGinnis]

Ah, it's nice to know that as time inexorably marches forward and Usenet becomes AOL becomes TikTok, as keyboards transition to phone screens transition to VR sensors, that some things, some things -- some things never change.

A key generated with gpg2.3 supports this encryption type and encryption in Windows (using the current Gpg4win 4.0.0) defaults to AEAD for a key generated with default settings. Since AEAD/type 20 is not supported yet by version 2.2, decryption on linux distros is not possible using version 2.2.X from their repositories.
