How do I configure "no padding"? Thank you. you should use the EVP interface instead of the low-level functions ret = EVP_DecryptInit_ex(&ctx, EVP_des_ecb(), NULL, myKey, NULL); assert(ret == 1); ret = EVP_CIPHER_CTX_set_padding(&ctx, 0); assert(ret == 1); and then EVP_Decrypt_Update(), EVP_DecryptFinal(). Similar for encryption. Hope this helps, Martin ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
