Method Detail

getFingerPrint

public static String getFingerPrint(Factory<? extends Digest> f,
                                    String s)
                             throws Exception

Parameters:

f - The Factory to create the Digest to use

s - The String to digest - ignored if null/empty, otherwise its UTF-8 representation is used as input for the fingerprint

Returns:

The fingerprint - null if null/empty input

Throws:

Exception - If failed to calculate the digest
