I'm trying to do an Encryption and Decryption in Java Android.
Below is my code for C#, I need to convert it to Java Android. Can someone help me how to do it?
I've been doing this for almost 2 days yet can't find any solutions on how to convert it. I'm newbie in Android.
public static string Encrypt(string toEncrypt)
{
byte[] keyArray;
byte[] toEncryptArray = UTF8Encoding.UTF8.GetBytes(toEncrypt);
System.Configuration.AppSettingsReader settingsReader = new AppSettingsReader();
string key = "KEY";
MD5CryptoServiceProvider hashmd5 = new MD5CryptoServiceProvider();
keyArray = hashmd5.ComputeHash(UTF8Encoding.UTF8.GetBytes(key));
hashmd5.Clear();
TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
tdes.Key = keyArray;
tdes.Mode = CipherMode.ECB;
tdes.Padding = PaddingMode.PKCS7;
ICryptoTransform cTransform = tdes.CreateEncryptor();
byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
tdes.Clear();
return Convert.ToBase64String(resultArray, 0, resultArray.Length);
}
public static string Decrypt(string cipherString)
{
try
{
byte[] keyArray;
byte[] toEncryptArray = Convert.FromBase64String(cipherString);
string key = "KEY";
MD5CryptoServiceProvider hashmd5 = new MD5CryptoServiceProvider();
keyArray = hashmd5.ComputeHash(UTF8Encoding.UTF8.GetBytes(key));
hashmd5.Clear();
TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
tdes.Key = keyArray;
tdes.Mode = CipherMode.ECB;
tdes.Padding = PaddingMode.PKCS7;
ICryptoTransform cTransform = tdes.CreateDecryptor();
byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
tdes.Clear();
return UTF8Encoding.UTF8.GetString(resultArray);
}
catch (Exception)
{
return "Invalid";
}
}
Try This,
package mypackage;
import java.security.MessageDigest;
import java.util.Arrays;

import javax.crypto.SecretKey;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

String decodedtext = new Main().decrypt(codedtext);
System.out.println(codedtext); // this is a byte array, you'll just see a reference to an array
System.out.println(decodedtext); // This correctly shows "neeraj"
}
public String encrypt(String message) throws Exception {
final MessageDigest md = MessageDigest.getInstance("md5");
final byte[] digestOfPassword = md.digest("KEY"
.getBytes("utf-8"));
final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
for (int j = 0, k = 16; j < 8;) {
keyBytes[k++] = keyBytes[j++];
}
final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
final Cipher cipher = Cipher.getInstance("DES/ECB/PKCS7Padding");
cipher.init(Cipher.ENCRYPT_MODE, key, iv);
final byte[] plainTextBytes = message.getBytes("utf-8");
final byte[] cipherText = cipher.doFinal(plainTextBytes);
// final String encodedCipherText = new sun.misc.BASE64Encoder()
// .encode(cipherText);
return Base64.encodeBase64String(cipherText);
}
public String decrypt(String input) throws Exception {
byte[] message = Base64.decodeBase64(input);
final MessageDigest md = MessageDigest.getInstance("md5");
final byte[] digestOfPassword = md.digest("KEY"
.getBytes("utf-8"));
final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
for (int j = 0, k = 16; j < 8;) {
keyBytes[k++] = keyBytes[j++];
}
final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
final Cipher decipher = Cipher.getInstance("DES/ECB/PKCS7Padding");
decipher.init(Cipher.DECRYPT_MODE, key, iv);
// final byte[] encData = new
// sun.misc.BASE64Decoder().decodeBuffer(message);
final byte[] plainText = decipher.doFinal(message);
return new String(plainText, "UTF-8");
}
}
Refer to the main function for usage.
I have updated my code. Your C# program gives output as a base64 string. But in java the input of decrypt and output of encrypt is byte array. Convert the byte array to base64 and it will work.
For Base64 operation in java you need the Apache Commons codec.
In java 8 you can use java.util.Base64

I'm trying to Encrypt and decrypt a string in java using the following code:
public byte[] encrypt(String message) throws Exception {
final MessageDigest md = MessageDigest.getInstance("md5");
final byte[] digestOfPassword = md.digest("MYKEY12345"
.getBytes("utf-8"));
final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
for (int j = 0, k = 16; j < 8;) {
keyBytes[k++] = keyBytes[j++];
}
final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
// final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
final Cipher cipher = Cipher.getInstance("DESede/ECB/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, key);
final byte[] plainTextBytes = message.getBytes("utf-8");
final byte[] cipherText = cipher.doFinal(plainTextBytes);
// final String encodedCipherText = new sun.misc.BASE64Encoder()
// .encode(cipherText);
Log.d("base64", Base64.getEncoder().encodeToString(cipherText));
return cipherText;
}
public String decrypt(byte[] message) throws Exception {
final MessageDigest md = MessageDigest.getInstance("md5");
final byte[] digestOfPassword = md.digest("MYKEY12345"
.getBytes("utf-8"));
final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
for (int j = 0, k = 16; j < 8;) {
keyBytes[k++] = keyBytes[j++];
}
final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
// final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
final Cipher decipher = Cipher.getInstance("DESede/ECB/PKCS5Padding");
decipher.init(Cipher.DECRYPT_MODE, key);
// final byte[] encData = new
// sun.misc.BASE64Decoder().decodeBuffer(message);
final byte[] plainText = decipher.doFinal(message);
return new String(plainText, "UTF-8");
}
usage:
byte[] codedtext = new Common().encrypt("HELLOWORLD!"); // Function to get the Encrption
Output:
base64: Ya9zBTukyOmdOh5/5vCaGA== // encrypted string converted to base64
Encrypted : [B#d41c149
ToDecrypt:
String decodedtext = new Common().decrypt(codedtext); // To decrypt String
Output:
Decrypted : HELLOWORLD! // from Encrypted string
Now if i use the same Key and String to get the encryption key online i get different values.
Using this link to verify my encryption/decryption.
I'm just starting in encryption/decryption so any help is appreciated about any thing that i'm doing wrong here.
You need
final byte[] plainText = decipher.doFinal(Base64.getDecoder().decode(message));
We have an application running in .NET for several years. It uses the below c# code for encryption and decryption of password. Now we have another application in Java to consume the same DB for authentication. Tried various ways but could not get an equivalent code in Java for the below encryption and decryption in C#. As there are lot of data encrypted using this logic and stored in DB, will not be able change the C# code. Could someone help with equivalent code in Java? Thanks in Advance.
private string passphrase = "XYZ";
public string EncryptData(string Data)
{
byte[] Results;
var UTF8 = new UTF8Encoding();
var HashProvider = new MD5CryptoServiceProvider();

TDESAlgorithm.Mode = CipherMode.ECB;
TDESAlgorithm.Padding = PaddingMode.PKCS7;
byte[] DataToEncrypt = UTF8.GetBytes(Data);
try
{
ICryptoTransform Encryptor = TDESAlgorithm.CreateEncryptor();
Results = Encryptor.TransformFinalBlock(DataToEncrypt, 0, DataToEncrypt.Length);
}
finally

It looks like the problem is not finding equivalent code, but to port your C# code to Java, but because of the C# references and .net assemblies used, to use equivalent Java libs that support Triple DES. Have you investigated equivalent Java libs for Triple Des? A quick search found this example:

I'm attempting to convert this C# encryption algorithm to Java; however, I keep retrieving slightly different encrypted results (haven't tried decryption yet). It may also be important to point out that I'm not able to change the C# code.
However when I call the encrypt function in C# on the string "test" it will return nmj8MjjO52y928Syqf0J+g== However in Java it'll return C6xyQjJCqVo=
The C#
private static String key = "012345678901234567890123";
public static string encrypt(String stringToEncrypt)
{
TripleDES des = CreateDES(key);
ICryptoTransform ct = des.CreateEncryptor();
byte[] input = Encoding.Unicode.GetBytes(stringToEncrypt);
byte[] output = ct.TransformFinalBlock(input, 0, input.Length);
//return output;
return Convert.ToBase64String(output);
}
public static String decrypt(string encryptedString)
{
byte[] input = Convert.FromBase64String(encryptedString);
TripleDES des = CreateDES(key);
ICryptoTransform ct = des.CreateDecryptor();
byte[] output = ct.TransformFinalBlock(input, 0, input.Length);
return Encoding.Unicode.GetString(output);
}
public static TripleDES CreateDES(string key)
{
MD5 md5 = new MD5CryptoServiceProvider();
TripleDES des = new TripleDESCryptoServiceProvider();
des.Key = md5.ComputeHash(Encoding.Unicode.GetBytes(key));
des.IV = new byte[des.BlockSize / 8];
return des;
}

Does anyone see what I'm overseeing?
You are missing two things. You are using a 16 length key on the c# side since it is not padded like the Java version. By default if the key is 16 bytes in length it will be padded with the first 8 bytes of the key.
To make this match on the Java side you will have to uncomment that line that adds the padding to the key:
for (int j = 0, k = 16; j < 8;) {
keyBytes[k++] = keyBytes[j++];
}
SecretKey secretKey = new SecretKeySpec(keyBytes, 0, 24, "DESede");
Also, on the java side there was a suggestion to make sure to use UTF-LE for the text. Make sure to use it for everything. So the lines:
byte[] digestOfPassword = md.digest(key.getBytes("UTF-16LE"));
byte[] plainTextBytes = clearText.getBytes("UTF-16LE");
In general I would make sure to set the c# params of all the tripledes object, and not depend on defaults.
Here are two versions that match in c# and java
Java
String key = "012345678901234567890123";
String clearText = "test";
MessageDigest md = MessageDigest.getInstance("md5");
byte[] digestOfPassword = md.digest(key.getBytes("UTF-16LE"));
byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
String byteText = Arrays.toString(keyBytes);
for (int j = 0, k = 16; j < 8;) {
keyBytes[k++] = keyBytes[j++];
}
SecretKey secretKey = new SecretKeySpec(keyBytes, 0, 24, "DESede");
IvParameterSpec iv = new IvParameterSpec(new byte[8]);
Cipher cipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, secretKey, iv);
byte[] plainTextBytes = clearText.getBytes("UTF-16LE");
byte[] cipherText = cipher.doFinal(plainTextBytes);
String output = Base64.encode(cipherText);
c#
string clearText = "test";
string key = "012345678901234567890123";
string encryptedText = "";
MD5 md5 = new MD5CryptoServiceProvider();
TripleDES des = new TripleDESCryptoServiceProvider();
des.KeySize = 128;
des.Mode = CipherMode.CBC;
des.Padding = PaddingMode.PKCS7;
byte[] md5Bytes = md5.ComputeHash(Encoding.Unicode.GetBytes(key));
byte[] ivBytes = new byte[8];
des.Key = md5Bytes;
des.IV = ivBytes;
byte[] clearBytes = Encoding.Unicode.GetBytes(clearText);
ICryptoTransform ct = des.CreateEncryptor();
using (MemoryStream ms = new MemoryStream())
{
using (CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(), CryptoStreamMode.Write))
{
cs.Write(clearBytes, 0, clearBytes.Length);
cs.Close();
}
encryptedText = Convert.ToBase64String(ms.ToArray());
}
Edited: Both versions now return the test case result "nmj8MjjO52y928Syqf0J+g=="
return Base64.encodeBase64String(cipherText);
im getting an error in this line.It suggest me to make a class in base64,but is there any standard class for Base64?Im using this to encrypt.

There isn't an official Base64 class in JDK.
I can suggest you to use this: Apache Commons Codec
you can use Base64Encoder and Base64Decoder for you purpose.
Change
Base64.encodeBase64String(cipherText)
to
new BASE64Encoder().encode(cipherText)
and
Base64.decodeBase64(message)
to
new BASE64Decoder().decodeBuffer(message)
I am new to Security in java.
I have two clear double length keys which was used for generating ZPK (under LMK) in Futurex HSM.
Below mentioned pin blocks were encrypted using ZPK.
Is there a way to decrypt the block using clear keys in java.
clear_1 = "801CB5C89DC416C149FB645BB36897AD"
clear_2 = "45B98FC7D33149E0512F0ED9135E5826"
encrypted_pin_block = "6288FA9534BF2AA3"
encrypted_pin_block = "B8D876F238348EB0"
Decrypted value for one of these encrypted blocks is 2222.
