Dear all:
I have just implemented an RSA signature using openssl. What I observe
is that signing the same data (a SHA-256 hash) multiple times with the
same RSA key always yields the same signature. I thought the data to
be signed would be padded with random bits to avoid this. My search on
the topic has hit a wall with PSS padding (implemented in rsa_pss.c
but undocumented). Is there any way I can pad my own data before
passing it to RSA_sign()?
Thanks for helping
