Anyone can help reviewing this?
There is a bug in RSASSA-PSS signature verification when the key size is
multiples of 8 plus 1 bit. The verification on the encoded message is
off by one and verification failed unexpectedly. I added a check and
adjusted the starting index for the verification. I added 1025 and 2049
to existing PSS tests to verify this fix.
Hm, is there really use of 1025/2049 bits RSA key in practice. But it's
a nice catch!
