Method Detail

decode

public static byte[] decode(String strEncoded)

Convert a String of BASE64 digits into a byte array, ignoring the equals (=) pad characters at the end. This is not URL safe

Parameters:

strEncoded -

Returns:

array of Base 256 bytes

decode

public static byte[] decode(String strEncoded,
                            boolean bURLSafe)

Convert a String of BASE64 digits into a byte array, ignoring the equals (=) pad characters at the end. This can be made URL safe by passing in true

Parameters:

strEncoded -

bURLSafe - whether (true) or not (false) the encoding is URL safe meaning it uses "-" and "_" in lieu of "+" and "/"

Returns:

array of Base 256 bytes

encode

public static String encode(byte[] bArray)

Transform a byte array into a string of the BASE64 characters. Each grouping of 3 bytes is transformed into 4 BASE64 bytes which use 6 bits rather than 8 bits. Pad with equals (=) when input length does not divide by 3 evenly. The resulting String is not URL safe.

Parameters:

bArray - Base 256 array of bytes to be encoded

Returns:

String of Base 64 bytes containing the encoding of the input array

encode

public static String encode(byte[] bArray,
                            boolean bURLSafe)

Transform a byte array into a string of the BASE64 characters. Each grouping of 3 bytes is transformed into 4 BASE64 bytes which use 6 bits rather than 8 bits. Pad with equals (=) when intput length does not divide by 3 evenly.

Parameters:

bArray - Base 256 array of bytes to be encoded

bURLSafe - whether (true) or not (false) the encoding is URL safe meaning it uses "-" and "_" in lieu of "+" and "/"

Returns:

String of Base 64 bytes containing the encoding of the input array

main

public static void main(String[] args)
