[gnutls-devel] GnuTLS | Verification of deterministic RSA-PSS signature fails (#953)

[Development of GNU's TLS library]

Nikos Mavrogiannopoulos commented:


To my understanding the RSA-PSS signature does not contain the salt size thus the salt size needs to be provided somehow. The verification functions will read the parameters from the certificate (see `fixup_spki_params()`) or assume some defaults. That's the case here, the verification function has no way to be told that this is a key with zero salt.
