ComputeSecretKDF Property

The key derivation function.

Syntax

public var computeSecretKDF: EccComputeSecretKDFs {
  get {...}
  set {...}
}

public enum EccComputeSecretKDFs: Int32 {
  case ekdSHA1 = 0
  case ekdSHA256 = 1
  case ekdSHA384 = 2
  case ekdSHA512 = 3
  case ekdMD2 = 4
  case ekdMD4 = 5
  case ekdMD5 = 6
  case ekdHMACSHA1 = 7
  case ekdHMACSHA256 = 8
  case ekdHMACSHA384 = 9
  case ekdHMACSHA512 = 10
  case ekdHMACMD5 = 11
  case ekdTLS = 12
  case ekdConcat = 13
}

Default Value

Remarks

This property specifies the key derivation function (KDF) and algorithm to use when calling ComputeSecret.

Possible values are:


0 (ekdSHA1)	SHA-1
1 (ekdSHA256 - default)	SHA-256
2 (ekdSHA384)	SHA-384
3 (ekdSHA512)	SHA-512
4 (ekdMD2)	MD2
5 (ekdMD4)	MD4
6 (ekdMD5)	MD5
7 (ekdHMACSHA1)	HMAC-SHA1
8 (ekdHMACSHA256)	HMAC-SHA256
9 (ekdHMACSHA384)	HMAC-SHA384
10 (ekdHMACSHA512)	HMAC-SHA512
11 (ekdHMACMD5)	HMAC-MD5
12 (ekdTLS)	TLS
13 (ekdConcat)	Concat

HMAC Notes

If an HMAC algorithm is selected HMACKey may optionally be set to specify the key.

TLS Notes

When set to TLS, TLSSeed and TLSLabel are required. In addition PrependSecret and AppendSecret are not applicable.

Concat Notes

If Concat is selected the following configuration settings are applicable:
