Method Detail

encode

public byte[] encode(byte[] rawBytes,
                     int maxLengthToEncode)

Encode a byte array using bcrypt's slightly-modified base64 encoding scheme. Note that this is *not* compatible with the standard MIME-base64 encoding.

Specified by:

encode in interface Radix64Encoder

Parameters:

rawBytes - the byte array to encode

maxLengthToEncode - the number of bytes to encode

Returns:

radix64-encoded string

Throws:

IllegalArgumentException - if the length is invalid

decode

public byte[] decode(byte[] utf8EncodedBytes)

Decode a string encoded using bcrypt's base64 scheme to a byte array. Note that this is *not* compatible with the standard MIME-base64 encoding.

Specified by:

decode in interface Radix64Encoder

Parameters:

utf8EncodedBytes - the string to decode

Returns:

an array containing the decoded bytes

Throws:

IllegalArgumentException - if maxolen is invalid
