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.

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
