Unless a sender is forcing that algo.
Correct. And if a sender forced that algo, they would be doing so in violation of OpenPGP. GnuPG will decrypt the message anyway, but it will print a warning that the sender violated your preferences (this warning is actually required by the OpenPGP spec). > Is there anything the disable-cipher-algo option is actually useful > for? Not in general use. It's handy for testing and debugging.
