Method

Stringsha256(String input)
Calculated the SHA-256 hash of the given input string. 
try {
    MessageDigest md = MessageDigest.getInstance("SHA-256");
    byte[] hashedBytes = md.digest(input.getBytes());
    StringBuilder output = new StringBuilder(hashedBytes.length);
    for (int i = 0; i < hashedBytes.length; i++) {
        String hex = Integer.toHexString(0xFF & hashedBytes[i]);
        if (hex.length() == 1)
            hex = "0" + hex;
...
