Method

Stringencode(byte[] source, int off, int len, byte[] alphabet, boolean doPadding)
Encodes a byte array into Base64 notation. 
byte[] outBuff = encode(source, off, len, alphabet,
        Integer.MAX_VALUE);
int outLen = outBuff.length;
while (doPadding == false && outLen > 0) {
    if (outBuff[outLen - 1] != '=') {
        break;
    outLen -= 1;
...
byte[]encode(byte[] source, int off, int len, byte[] alphabet, int maxLineLength)
Encodes a byte array into Base64 notation. 
int lenDiv3 = (len + 2) / 3; 
int len43 = lenDiv3 * 4;
byte[] outBuff = new byte[len43 
        + (len43 / maxLineLength)]; 
int d = 0;
