Hello out there, I am writing a Linux tool for user authentification that uses RSA encryption. I have some usernames and hexadecimal key values (2048 bit modulus, in this application, the public exponent is fixed for all keys) stored in a file. When reading out the modulus value, I am using the BN_hex2bn() function which gives me a (whee!) 2045 bit modulus 'cause the upper three bits are set to zero. I don't know if this is really the problem, but when trying to do a RSA_public_encrypt(), I get the following error: "error:0306E06C:bignum routines:BN_mod_inverse:no inverse" and RSA_public_encrypt() fails. I have seen some PEM_xxx functions around, but I haven't found any documentation for them, yet. I would like to keep overhead small, so I am looking for an easy way to read in RSA public keys (later, I will have to read RSA private keys which I will get as hex strings representing the private key values). So, how do I do it correctly? Thanks for any answers, Stephan A.
