Is is 24 for des3. You can use EVP_MAX_KEY_LENGTH for the key and EVP_MAX_IV_LENGTH for the iv. The EVP_BytesToKey() call uses the correct lengths automatically. > Also, how will i eventually add salt to this (specified in the command line > as -salt but with no number present) > You have to mimic the format used by the enc utility, see the docs. You read the salt from the stream on decrypt and use that. If you need to encrypt you generate a random salt with RAND_bytes(). Steve. -- Dr Stephen N. Henson. OpenSSL project core developer.
