What cipher mode (CBC, CFB, CTR, ...) and depending on that what kind of
padding to you use. How do you call gcry_cipher_open?

Sure it can't know that and will happlity decrypt this.
gcry_cipher_decrypt can's distinguish between cleartext and ciphertext.
The upper layer (i.e. the protocol) must define how this can be done.

gcry_cipher_decrypt can't return an error except for cases where you you
pass an invalid data length (e.g. not a multiple of the blocklength).
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
