That's not a niche implementation.
Thunderbird 78's default OpenPGP implementation is rnp. According to the interoperability test suite, rnp is able to use the "Alice" key from the "OpenPGP Example Keys and Certificates" I-D. https://tests.sequoia-pgp.org/#Encrypt-Decrypt_roundtrip_with_key__Alice_ https://tools.ietf.org/html/draft-bre-openpgp-samples-00#section-2 The "Alice" certificate uses: Primary key algorithm: Ed25519 Subkey algorithm: Curve25519 Neal _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
