Interface Radix64Encoder

All Known Implementing Classes:

Radix64Encoder.Default

public interface Radix64Encoder

Encoder for the custom Base64 variant of BCrypt (called Radix64 here). It has the same rules as Base64 but uses a different mapping table than the various RFCs

According to Wikipedia:

Unix stores password hashes computed with crypt in the /etc/passwd file using radix-64 encoding called B64. It uses a mostly-alphanumeric set of characters, plus . and /. Its 64-character set is "./0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz". Padding is not used.

Modifier and Type	Interface and Description
static class	Radix64Encoder.Default This class implements an encoder for encoding byte data using the Base64 encoding scheme as used in OpenBSD which is not compatible with the RFC Base64 schemas.

Method Summary

Modifier and Type	Method and Description
byte[]	decode(byte[] utf8EncodedRadix64String) From a UTF-8 encoded string representing radix64 encoded data as byte array, decodes the raw bytes from it.
byte[]	encode(byte[] rawBytes) Encode given raw byte array to a Radix64 style, UTF-8 encoded byte array.

Method Detail

encode

byte[] encode(byte[] rawBytes)

Encode given raw byte array to a Radix64 style, UTF-8 encoded byte array.

Parameters:

rawBytes - to encode

Returns:

UTF-8 encoded string representing radix64 encoded data

decode

byte[] decode(byte[] utf8EncodedRadix64String)

From a UTF-8 encoded string representing radix64 encoded data as byte array, decodes the raw bytes from it.

Parameters:

utf8EncodedRadix64String - from a string get it with "m0CrhHm10qJ3lXRY.5zDGO".getBytes(StandardCharsets.UTF8)

Returns:

the raw bytes encoded by this utf-8 radix4 string
