Method Detail

decodeBase64Local

public static byte[] decodeBase64Local(byte[] base64Values)
                                throws IllegalArgumentException

Convert a array of base64 encoded byte in a array of bytes, returning the bytes original values. RFC 2045. Base64 only uses 6 bits, so fits each set of 4 base64 in 3 bytes Base64 | c1 | c2 | c3 | c4 | |7 6 5 4 3 2 1 0:7 6 5 4 3 2 1 0:7 6 5 4 3 2 1 0| Byte | b1 | b2 | b3 |

Parameters:

base64Values - is an array of base64 encoded values

Returns:

an array of bytes with the original values

Throws:

IllegalArgumentException - if the provided base64 values are null, or do not fits the required length

encodeBase64Local

public static byte[] encodeBase64Local(byte[] dataValues)
                                throws IllegalArgumentException

Convert a array of bytes in a array of MIME Base64 values. RFC 2045.

Parameters:

dataValues - is an array of bytes with the original values

Returns:

an array of base64 encoded values

Throws:

IllegalArgumentException - if the provided base64 values are null, or do not fits the required length

encodeBase64StringLocal

public static String encodeBase64StringLocal(byte[] dataValues)
                                      throws IllegalArgumentException

Convert a array of bytes in a array of MIME Base64 values. RFC 2045.

Parameters:

dataValues - is an array of bytes with the original values

Returns:

a string with the base64 encoded values

Throws:

IllegalArgumentException - if the provided base64 values are null, or do not fits the required length
