KeyDerivationFunction Property
The key derivation function.
Syntax
__property TipcECCKeyDerivationFunctions KeyDerivationFunction = {read=FKeyDerivationFunction, write=FSetKeyDerivationFunction, default=0};
enum TipcECCKeyDerivationFunctions {
ekdSHA1=0,
ekdSHA256=1,
ekdSHA384=2,
ekdSHA512=3,
ekdMD2=4,
ekdMD4=5,
ekdMD5=6,
ekdHMACSHA1=7,
ekdHMACSHA256=8,
ekdHMACSHA384=9,
ekdHMACSHA512=10,
ekdHMACMD5=11,
ekdTLS=12
};
Default Value
0
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.
