gnutls_cipher_hd_t handle is a gnutls_cipher_hd_t type const void * ctext the data to decrypt size_t ctext_len the length of data to decrypt void * ptext the decrypted data size_t ptext_len the available length for decrypted data

This function will decrypt the given data using the algorithm specified by the context. For block ciphers the ctext_len must be a multiple of the block size. For the supported ciphers the plaintext data length will equal the ciphertext size. Note that in AEAD ciphers, this will not check the tag. You will need to compare the tag sent with the value returned from gnutls_cipher_tag().
