Completes the hash computation by performing final operations such as padding.

Usage

From source file:Main.java

public static String hashImgUrl(String imgUrl) throws NoSuchAlgorithmException {
    String imgKey = null;//from  www.ja v  a2 s  . co  m
    MessageDigest m = MessageDigest.getInstance("MD5");
    m.reset();
    m.update(imgUrl.getBytes());
    byte[] digest = m.digest();
    BigInteger bigInt = new BigInteger(1, digest);
    imgKey = bigInt.toString(16);
    while (imgKey.length() < 32)
        imgKey = "0" + imgKey;
    return imgKey;
}
