Hello, I believe using the ECB mode for encryption does not make use of an IV but EVP_EncryptUpdate takes an IV as a parameter. Is passing NULL to it the correct thing to do? i.e.
EVP_EncryptUpdate(&ctx, ciphertext, &ctlen, plaintext, ptlen) Thanks.... ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
