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

Usage

From source file:customerproject.customerutilities.Utilities.java

public static String SHA256(String email, String password)
        throws NoSuchAlgorithmException, UnsupportedEncodingException {

    String text = email + "." + password;

    byte[] sha256hash = new byte[32];
    md.update(text.getBytes("iso-8859-1"), 0, text.length());
    sha256hash = md.digest();

    //return Base64.encodeBase64String(sha256hash);
    return Base64.encodeBase64URLSafeString(sha256hash);
    //String hex = convertToHex(sha256hash);
