Method Detail

encode

public static java.lang.String encode(java.lang.String s)

base-64 encode a string

Parameters:

s - The ascii string to encode

encode

public static java.lang.String encode(byte[] src)

base-64 encode a byte array

Parameters:

src - The byte array to encode

encode

public static java.lang.String encode(byte[] src,
                                      int start,
                                      int length)

base-64 encode a byte array

Parameters:

src - The byte array to encode

start - The starting index

len - The number of bytes

decode

public static byte[] decode(java.lang.String s)

A Base64 decoder. This implementation is slow, and doesn't handle wrapped lines. The output is undefined if there are errors in the input.

Parameters:

s - a Base64 encoded string
