typedef drip_hash_cb_t

Callback function type for producing hashes.

typedef int(* drip_hash_cb_t) (void *context, const uint8_t *input, size_t input_length, uint8_t *buffer, size_t buffer_size, size_t *output_length);

Called by drip_hash() to perform the actual hashing of the payload.

Parameters:

• context Opaque context passed to the callback.
• input Pointer to the payload to hash.
• input_length Length of the payload in bytes.
• buffer Output buffer for the hash.
• buffer_size Size of the hash buffer in bytes.
• output_length Receives resulting hash length written.

Return value:

• 0 on success.
• Non-zero on hashing failure.
