Method

Stringdigest(String provider, File file, int radix)
Digest a file with a specified provider. 
String result;
BufferedInputStream bis = null;
try {
    MessageDigest messageDigest = MessageDigest.getInstance(provider);
    bis = new BufferedInputStream(new FileInputStream(file));
    byte[] buffer = new byte[8192];
    int n;
    while ((n = bis.read(buffer)) != -1)
...
Stringdigest(String raw, String algorithm)
digest 
if (raw == null || "".equals(raw))
    return "";
MessageDigest md;
try {
    md = MessageDigest.getInstance(algorithm);
} catch (NoSuchAlgorithmException e) {
    throw new RuntimeException(e);
md.update(raw.getBytes());
StringBuilder sb = new StringBuilder();
for (byte b : md.digest()) {
    String hex = String.format("%02x", b);
    sb.append(hex);
return sb.toString();
Stringdigest(String s, String algorithm)
Computes digest of given input String. 
int i;
MessageDigest md = MessageDigest.getInstance(algorithm);
byte[] hash = md.digest(s.getBytes());
StringBuilder sb = new StringBuilder(2 * hash.length);
for (i = 0; i < hash.length; i++) {
    int b = hash[i] & 0xff;
    if (b < 16) {
        sb.append('0');
...
byte[]digest(String source)
digest 
MessageDigest md = MessageDigest.getInstance("SHA1");
md.update(source.getBytes());
return md.digest();
Stringdigest(String source, byte[] salt)
digest 
try {
    return new String(encode(digest(source.getBytes(DEFAULT_ENCODING), salt)));
} catch (UnsupportedEncodingException ex) {
    throw new RuntimeException("PasswordCrypter's error has occured!", ex);
} catch (RuntimeException ex) {

Stringdigest(String source, String algorythm)
digest 
if (source == null || source.length() == 0) {
    return source;
try {

Stringdigest(String strSource)
digest 
StringBuffer digest = new StringBuffer();

try {
    algorithm = MessageDigest.getInstance("MD5");
} catch (NoSuchAlgorithmException exc) {
    throw new RuntimeException(exc);

...
Stringdigest(String text, String algorithm)
Create the hash/digest code for a given text. 
if (text == null) {
    throw new IllegalArgumentException(new NullPointerException());
