Expand description

\brief This function checks the tag for AEAD ciphers. Currently supported with GCM and ChaCha20+Poly1305. This must be called after mbedtls_cipher_finish().

\param ctx The generic cipher context. This must be initialized. \param tag The buffer holding the tag. This must be a readable buffer of at least \p tag_len Bytes. \param tag_len The length of the tag to check.
