Method

StringencodeWebSafe(byte[] source, boolean doPadding)
Encodes a byte array into web safe Base64 notation. 
return encode(source, 0, source.length, WEBSAFE_ALPHABET, doPadding);
StringencodeWebSafe(byte[] source, boolean doPadding)
Encodes a byte array into web safe Base64 notation. 
return encode(source, 0, source.length, WEBSAFE_ALPHABET, doPadding);
byte[]encode3to4(byte[] b4, byte[] threeBytes, int numSigBytes, int options)
Encodes up to the first three bytes of array threeBytes and returns a four-byte array in Base64 notation. 
encode3to4(threeBytes, 0, numSigBytes, b4, 0, options);
return b4;
byte[]encode3to4(byte[] source, int srcOffset, int numSigBytes, byte[] destination, int destOffset, int options)

Encodes up to three bytes of the array source and writes the resulting four Base64 bytes to destination. 

byte[] ALPHABET = getAlphabet(options);
int inBuff = (numSigBytes > 0 ? ((source[srcOffset] << 24) >>> 8)
        : 0)
