Ok, long story short: I think I understand that sha256 produces 32 byte hashes (32 characters in length). I think I also understand that the hash length is...
... I'd guess that it's the second strlen(). Since hash_buffer might have NULL bytes in it, strlen will take the null terminator, and think the string ends...

Hello everyone, First of all, I am using a modified version of libtomcrypt 0.92. That said, I am having a problem using libtomcrypt to generate RSA keys that...
Hi ! ;) I'm new from today in the group!! I took a look at the doc of LibTomCrypt and I haven't seen a function which generate a (RSA) Key Pair (public and...
Ahh sorry I forgot to point that out. The public key is stored in key.e and the private is in key.d. If you want to encrypt something, just call rsa_exptmod...
Oh yeah, I thought about mentioning that too. Encrypt: rsa_pad(); rsa_exptmod(PK_PUBLIC); Decrypt: rsa_exptmod(PK_PRIVATE); rsa_depad(); And happy birthday...

Hi, rsa_make_key uses rand_prime which creates an (n*8+1) bit number (requiring n+1 bytes to represent it), guaranteeing that the number is a suitable modulus...
