L.S.
I'm having a problem using DSA_verify. The actual call in my C program
(including some context), the results on stdout and lookup of the
meaning of openssl error codes are given below. I still cannot conclude
from the "meaning" of the error messages what I've done wrong. My
initial guess was that some input (hash, sig, ..) has a bad size, but I
can't think of which input that could be.
Can any body please help me to find what's wrong
...
==> result = DSA_verify(NID_sha1, hash, 20, \
sig, 20, dsa);
sure that your signature is 20 bytes long, as it is a structure
containing two 160 bit numbers it seems a little bit short to me :)
