Method Detail

getHashAlgName

public static java.lang.String getHashAlgName(long hashMechanism)

asUnsignedByteArray

public static byte[] asUnsignedByteArray(java.math.BigInteger bn)

toFullHex

public static java.lang.String toFullHex(long value)

Converts a long value to a hexadecimal String of length 16. Includes leading zeros if necessary.

Parameters:

value - The long value to be converted.

Returns:

The hexadecimal string representation of the long value.

toHex

public static java.lang.String toHex(byte[] value)

Converts a byte array to a hexadecimal String. Each byte is presented by its two digit hex-code; 0x0A -> "0a", 0x00 -> "00". No leading "0x" is included in the result.

Parameters:

value - the byte array to be converted

Returns:

the hexadecimal string representation of the byte array

toHex

public static java.lang.String toHex(byte[] value,
                                     int ofs,
                                     int len)

decodeHex

public static byte[] decodeHex(java.lang.String encoded)
