Re: [openpgp] [RFC4880bis PATCH] WIP: bind wire format representations to specific pubkey algorithms

2021-06-05 11:03:41
* Daniel Kahn Gillmor:

The OpenPGP standard is in a bit of a mess when it comes to wire
formats for public key algorithms.

There are not infrequent reports of interoperability problems (most
recently https://dev.gnupg.org/T5464), and difficulties for
implementers in understanding what is expected.

I think this issue also affects RSA data because the way OpenPGP
specifies the operations, they are octet strings of a specific length,
not integers, and may including leading zero bytes.
