Public Methods

Method	Description
From ( string ContentType, byte Data, int Bits ) : byte[]	Compute UDF from binary data and content type with specified precision.
FromEscrowed ( byte Data, int Bits ) : byte[]	Calculate a UDF fingerprint from a secret key used to escrow a private key in the mesh.
FromKeyInfo ( byte Data ) : byte[]	Calculate a UDF fingerprint from a PKIX KeyInfo blob with specified precision.
FromKeyInfo ( byte Data, int Bits ) : byte[]	Calculate a UDF fingerprint from a PKIX KeyInfo blob with specified precision.
Random ( ) : string	Return a random sequence as a UDF
Random ( int Bits ) : string	Return a random sequence as a UDF
SHA1 ( byte Data ) : byte[]	Calculate a SHA-1 fingerprint
SHA256 ( byte Data ) : byte[]	Calculate a SHA-1 fingerprint
ToString ( byte Data ) : string	Convert a binary UDF to a string.
ToString ( string ContentType, byte Data, int Bits ) : string	Calculate a UDF fingerprint from an OpenPGP key with specified precision.
Validate ( string Test, string Value ) : void	Check that a UDF fingerprint satisfies a test value. At present the test must be exact. It is possible that this can be relaxed so that a longer fingerprint will satisfy a shorter one.

Method Details

From() public static method
