Method

StringdigestHmacToBase64(String algorithm, String msg, byte[] privateKey)
Firma un mensaje y devuelve la firma en formato string base 64 
Mac mac = Mac.getInstance(algorithm);
SecretKeySpec key = new SecretKeySpec(privateKey, algorithm);
mac.init(key);
byte[] macBytes = mac.doFinal(msg.getBytes("UTF-8"));

byte[]digestStream(MessageDigest digest, InputStream is)
digest Stream 
byte[] buf = new byte[4096];
int nRead;
while ((nRead = is.read(buf)) != -1) {

voiddigestString(MessageDigest md, String s)
Utility method to digest String s. 
int len = s.length();
byte[] b = new byte[len];
for (int i = 0; i < len; i++) {
    char c = s.charAt(i);
    if (c < 127) {

StringdigestString(String input)
Creates an MD5 hash of the input string. 
String digested = "";

StringdigestString(String pass, String algorithm)
digest String 
MessageDigest md;
ByteArrayOutputStream bos;
md = MessageDigest.getInstance(algorithm);
byte[] digest = md.digest(pass.getBytes());
return new String(digest);
StringdigestString(String pass, String algorithm)
Calculate digest of given String using given algorithm. 
MessageDigest md;
