compute_secret_kdf Property
The key derivation function.
Syntax
def get_compute_secret_kdf() -> int: ... def set_compute_secret_kdf(value: int) -> None: ...
compute_secret_kdf = property(get_compute_secret_kdf, set_compute_secret_kdf)
Default Value
1
Remarks
This property specifies the key derivation function (KDF) and algorithm to use when calling compute_secret.
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:
- ConcatAlgorithmId (required)
- ConcatPartyUInfo (required)
- ConcatPartyVInfo (required)
- ConcatSuppPubInfo
- ConcatSuppPrivInfo
- ConcatHashAlgorithm
