Hello,

You may for example use:
EVP_EncryptInit_ex(&ctx, EVP_aes_256_cbc(), NULL, key, iv);
printf("\ncipher parameters:\n");
printf(" block size: %d\n", EVP_CIPHER_CTX_block_size(&ctx));
printf(" key length: %d\n", EVP_CIPHER_CTX_key_length(&ctx));
printf(" iv length: %d\n", EVP_CIPHER_CTX_iv_length(&ctx));
Best regards,
