Method Detail

encode

public static String encode(byte[] bytes)

Encode an array of binary bytes into a Base32 string. Should not fail (the only possible exception is that the returned string cannot be allocated in memory)

decode

public static byte[] decode(String base32)
                     throws IllegalArgumentException

Decode a Base32 string into an array of binary bytes. May fail if the parameter is a non canonical Base32 string (the only other possible exception is that the returned array cannot be allocated in memory)

Throws:

IllegalArgumentException
