Kdf.Bytes Method

Generate a key-encryption key (KEK) from input keying material (IKM) using a key derivation function (KDF).

Syntax

public static byte[] Bytes(
	int dkLen,
	byte[] ikm,
	Kdf.KdfAlg kdfAlg,
	Kdf.HashAlg hashAlg,
	byte[] sharedInfo,
	string paramString
)

Public Shared Function Bytes ( _
	dkLen As Integer, _
	ikm As Byte(), _
	kdfAlg As Kdf.KdfAlg, _
	hashAlg As Kdf.HashAlg, _
	sharedInfo As Byte(), _
	paramString As String _
) As Byte()

Parameters

dkLen

Required length of output key material in bytes.

ikm

Input key material/shared secret.

kdfAlg

Type: Kdf.KdfAlg
Key derivation function to use.

hashAlg

Type: Kdf.HashAlg
Hash algorithm to use with the key derivation function (default is SHA-1)

sharedInfo

SharedInfo (optional)

paramString

Optional parameters. Set as "" for defaults. Pass attribute-value salt=<hex-digits> to set the optional salt parameter for the HKDF algorithm, e.g. "salt=606162636465666768696a6b6c6d6e6f;"
