Method

StringbyteArrayToBase64(byte[] a)
Translates the specified byte array into a Base64 string as per Preferences.put(byte[]). 
return byteArrayToBase64(a, false);
StringbytesToBase64(byte[] bytes)
bytes To Base 
char base64[] = new char[bytes.length];
for (int i = 0; i < bytes.length; i++) {
    base64[i] = sBitChars[bytes[i]];
return new String(base64);
StringbytesToBase64(byte[] bytes, int length)
Converts a maximum of three bytes to 4 Base64 characters 
String result = "";
if (length == 3) {
    result += bitsToBase64((byte) ((bytes[0] & 0xFC) >> 2));
    result += bitsToBase64((byte) ((bytes[0] & 0x03) << 4 | (bytes[1] & 0xF0) >> 4));
    result += bitsToBase64((byte) ((bytes[1] & 0x0F) << 2 | (bytes[2] & 0xC0) >> 6));
    result += bitsToBase64((byte) (bytes[2] & 0x3F));
if (length == 2) {
...
StringbyteToBase64(byte[] data)
From a byte[] returns a base 64 representation 
return Base64.getEncoder().encodeToString(data);
