HMAC implementation (RFC 2104).

class HMAC

Types 1

classHMAC : MAC

HMAC implementation (RFC 2104).

Fields

private Hash _hash

private ubyte[] _kIpad

private ubyte[] _kOpad

Methods

void initialize(const(ubyte)[] key)Initializes (or re-initializes) the HMAC with the given secret key.

MAC update(const(ubyte)[] input)Updates the HMAC with the given input data. Params: input = The data to update with. Returns: The MAC instance itself for method chaining.

ubyte[] finish()Finalizes the HMAC computation and returns the tag. Resets the HMAC to its initial state (ready for a new message with the same key). Returns: The authentication tag.

void reset()Resets the HMAC to its initial state.

size_t size() @property constReturns: The size of the MAC tag in bytes.

Constructors

this(Hash hash, const(ubyte)[] key)Constructs a new HMAC instance. Params: hash = The hash algorithm to use. This instance will be used exclusively by HMAC. key = The secret key.
