Method

StringencodeBase64(String input)
Creates a base 64 encoded string from the given input string. 
return DatatypeConverter.printBase64Binary(input.getBytes(StandardCharsets.UTF_8));
StringencodeBase64(String stringValue)
encode Base 
byte[] bytesValue = stringValue.getBytes("UTF-8");
String encodedValue = DatatypeConverter.printBase64Binary(bytesValue);
return encodedValue;
StringencodeBase64Binary(byte[] data)
encode Base Binary 
return DatatypeConverter.printBase64Binary(data);
StringfromBase64(String base64)
from Base 
byte[] encodedHelloBytes = DatatypeConverter.parseBase64Binary(base64);
return new String(encodedHelloBytes, StandardCharsets.UTF_8);
byte[]fromBase64(String hex)
Converts a string of hexadecimal characters into a byte array. 
return DatatypeConverter.parseBase64Binary(hex);
StringgetBase64(byte[] bytes)
get Base 
String h = DatatypeConverter.printBase64Binary(bytes);
h = h.replaceFirst("=*$", "");
h = h.replace('+', '-');
h = h.replace('/', '_');
return h;
StringgetHashBase64(String origStr, String digestAlgorithm)
get Hash Base 
MessageDigest sha = MessageDigest.getInstance(digestAlgorithm);
byte[] resultDigest = sha.digest(origStr.getBytes());
return DatatypeConverter.printBase64Binary(resultDigest);
byte[]readBase64Bytes(String str)
read Base Bytes 
return DatatypeConverter.parseBase64Binary(str);
StringreadFileToBase64(String filePath)
Lee todos los bytes de un archivo en particular y lo convierte a un string en Base64 
Path path = FileSystems.getDefault().getPath(filePath);
byte[] bytesFromFile = Files.readAllBytes(path);
return byteToBase64(bytesFromFile);
Stringsha256SaltBase64(String password, String salt)
sha256 encryption with salt. 
try {
    MessageDigest digest = MessageDigest.getInstance("SHA-256");
    digest.reset();
    byte[] binaryData = digest.digest((salt + password).getBytes("UTF-8"));
    return DatatypeConverter.printBase64Binary(binaryData);
} catch (UnsupportedEncodingException | NoSuchAlgorithmException e) {
    throw new Exception("Error al encriptar el password.", e);
