Field Detail

utf8

public static final Charset utf8

Method Detail

hashValues

public static BigInteger hashValues(MessageDigest digest,
                                    String... values)

leadingZerosPad

public static String leadingZerosPad(String value,
                                     int desiredLength)

hashCredentials

public static String hashCredentials(MessageDigest digest,
                                     String salt,
                                     String identity,
                                     String password)

toHexString

public static String toHexString(byte[] bytes)

http://stackoverflow.com/a/9855338 Compute a String in HexDigit from the input. Note that this string may have leading zeros but hex strings created by toString(16) of BigInteger would strip leading zeros.

Parameters:

bytes - Raw byte array

Returns:

Hex encoding of the input
