Hi, My use of the Crypto++ library has gone very well, but I have a small question...
If I use RSAES_OAEP_Encryptor & RSAES_OAEP_Decryptor everything is fine. (I'm using a 2048-bit key from PEM files generated by OpenSSL). My question is this: Will the length of ciphertext produced by encryptor.Encrypt(...) always equal decryptor.FixedCiphertextLength() or can be be less than that? I only ask as this is in a library used by a number of applications and I need to sanity check parameters..... BTW. Is there any faster was to encrypt/decrypt using RSA which maintains at least the same level of security provided by OAEP? With a 2048 bit key, on an example test box I'm finding it takes about 80uS to encode a short string and 4.3mS (53 times longer) to decrypt. I know that RSA decryption is slow, but.... the system is running XP Pro SP3/Xeon E5520 and was compiled with VS2008 with /MD rather than /MT. I can't use a short key...
