Method Detail

encode

public static String encode(byte[] d,
                            int len)
                     throws IllegalArgumentException

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

Parameters:

d - the byte array to encode

len - the number of bytes to encode

Returns:

base64-encoded string

Throws:

IllegalArgumentException - if the length is invalid

decode

public static byte[] decode(String s,
                            int maxolen)
                     throws IllegalArgumentException

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.

Parameters:

s - the string to decode

maxolen - the maximum number of bytes to decode

Returns:

an array containing the decoded bytes

Throws:

IllegalArgumentException - if maxolen is invalid
