Class Base32String

java.lang.Object

org.forgerock.android.auth.util.Base32String

public class Base32String
extends java.lang.Object

Encodes arbitrary byte arrays as case-insensitive base-32 strings.

The implementation is slightly different than in RFC 4648. During encoding, padding is not added, and during decoding the last incomplete chunk is not taken into account. The result is that multiple strings decode to the same byte array, for example, string of sixteen 7s ("7...7") and seventeen 7s both decode to the same byte array.
