Để mã hóa password trong Java, chúng ta có thể sử dụng class bên dưới:
package helper;
import java.math.*;
import java.security.*;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
public class PasswordEncryption {
public static String MD5(String input) {
try {
MessageDigest md = MessageDigest.getInstance("MD5");
byte[ messageDigest = md.digest(input.getBytes());
BigInteger number = new BigInteger(1, messageDigest);
String hashtext = number.toString(16);
while (hashtext.length() < 32) {
hashtext = "0" + hashtext;
}
return hashtext;
} catch (NoSuchAlgorithmException e) {
throw new RuntimeException(e);
}
}
public static String SHA1(String input) throws NoSuchAlgorithmException {
MessageDigest mDigest = MessageDigest.getInstance("SHA1");
byte[ result = mDigest.digest(input.getBytes());
StringBuffer sb = new StringBuffer();
for (int i = 0; i < result.length; i++) {
sb.append(Integer.toString((result [i & 0xff) + 0x100, 16).substring(1));
}
return sb.toString();
}
}
