Love it! I think I am going to use “post-heffalump crypto” from now on. :D

But keep https://www.cs.auckland.ac.nz/~pgut001/pubs/heffalump_crypto.pdf in mind ;-)

I wrote it with PQC security level in mind which requires AES256 for the session key as well.

That is what I expected. Meanwhile I re-read the code and history and can tell that the comment is not correct. I wrote it with PQC security level in mind which requires AES256 for the session key as well. However, during the migration phase and as long as --require-pqc-encryption is not enable we should allow an AES-128 session key. This is for the rare case that encryption is also done for non pqc keys which don't have the AES-256 capability set.

Here you are:

At gnupg/g10/pubkey-enc.c you will find

I have replaced the expiring test key with a new non-expiring test key.

@ikloecker: Do you still have the private key for tests/json/key-with-revokers.asc somewhere? We need to remove the expiration date due to T7471.

This looks like a bug with gnutls which is the only tool that fails :
