return DatatypeConverter.printBase64Binary(data.getBytes("UTF-8"));
Stringbase64EncodeBasicCredentials(String username, String password)
Base64-encodes the specified username and password for Basic Authorization for HTTP requests or upstream proxy authorization. 
String credentialsToEncode = username + ':' + password;
byte[] credentialsAsUtf8Bytes = credentialsToEncode.getBytes(StandardCharsets.UTF_8);
return DatatypeConverter.printBase64Binary(credentialsAsUtf8Bytes);
Stringbase64FromBinary(byte[] value)
Convert (encode) the given binary value using Base64. 
return DatatypeConverter.printBase64Binary(value);
Stringbase64FromString(String value)
Convert the given String to UTF-8, encode the result with Base64, and return the encoded value as a string. 
return DatatypeConverter.printBase64Binary(toBytes(value));
byte[]base64ToByte(String data)
From a base 64 representation, returns the corresponding byte[]
