I modified the code with using strlen(Plaintext) which is 16-byte long, but
still not understand if need to call EVP_EncryptFinal_ex() after called
EVP_EncryptUpdate().
If I call like this, I get 32-byte return(The first 16 byte string equal to
Ciphertext in the test case)
ret = EVP_EncryptUpdate(&ctx, out, outl, in, inl);
if(!ret) abort();
len += *outl;
ret = EVP_EncryptFinal_ex(&ctx, out+len, outl);
if(!ret) abort();
len += *outl;
Or if I call like this, the result is error (return 16 byte, but not equal to
Ciphertext in the test case)
ret = EVP_EncryptUpdate(&ctx, out, outl, in, inl);
if(!ret) abort();
ret = EVP_EncryptFinal_ex(&ctx, out, outl);
if(!ret) abort();
len += *outl;

This is a 17-byte string.
> out = EncryptTest((unsigned char*)Plaintext,
> sizeof(Plaintext), key,iv, &outl);
sizeof(Plaintext) == 17
