KeyDerivationFunction Property

The key derivation function.

Syntax

int GetKeyDerivationFunction();

int SetKeyDerivationFunction(int iKeyDerivationFunction);

Possible Values

  EKD_SHA1(0), 
  EKD_SHA256(1), 
  EKD_SHA384(2), 
  EKD_SHA512(3), 
  EKD_MD2(4), 
  EKD_MD4(5), 
  EKD_MD5(6), 
  EKD_HMACSHA1(7), 
  EKD_HMACSHA256(8), 
  EKD_HMACSHA384(9), 
  EKD_HMACSHA512(10), 
  EKD_HMACMD5(11), 
  EKD_TLS(12)

Default Value

Remarks

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

Possible values are:


0 (ekdSHA1 - default)	SHA-1
1 (ekdSHA256)	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

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

Note: When set to TLS, TLSSeed and TLSLabel are required.
