class HKDF

Types 1

classHKDF : KDF

HKDF Implementation.

Provides mechanism to derive cryptographic keys from input keying material (IKM) and optional salt and info.

Fields

private HashFactory _hashFactory

Methods

ubyte[] derive(const(ubyte)[] secret, const(ubyte)[] salt, size_t length)Derives a key of the specified length using the standard KDF interface.

ubyte[] derive(const(ubyte)[] secret, const(ubyte)[] salt, size_t length, KDFParams params)Derives a key using the given parameters.

ubyte[] derive(const(ubyte)[] secret, const(ubyte)[] salt, const(ubyte)[] info, size_t length)Derives a key with context information.

ubyte[] extract(const(ubyte)[] salt, const(ubyte)[] ikm)HKDF-Extract Step.

ubyte[] expand(const(ubyte)[] prk, const(ubyte)[] info, size_t length)HKDF-Expand Step.

Constructors

this(HashFactory hashFactory)Constructs a HKDF instance.
