We Keep Coding

I am trying to convert Java AES encryption to NodeJs. This is what I have tried so far

Java encryption code.
import java.security.spec.KeySpec;
import java.util.Base64;
import java.util.List;
import java.util.Map;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.PBEKeySpec;
import javax.crypto.spec.SecretKeySpec;
import org.json.simple.JSONObject;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.jarvis.accountopeningv2.model.PartChanRequestDTO;
import com.jarvis.accountopeningv2.model.TemplateDTO;
public class SecurityService {
private static final String ALGORITHM = "AES/CBC/PKCS5PADDING";
public static String encryptpayload(String value, String key) {
String encryptedData = null;
try {
IvParameterSpec iv = new IvParameterSpec(key.substring(0, 16).getBytes("UTF-8"));
SecretKeySpec skeySpec = new SecretKeySpec(key.substring(0, 32).getBytes("UTF-8"), "AES");
Cipher cipher = Cipher.getInstance(ALGORITHM);
cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);
byte[] encrypted = cipher.doFinal(value.getBytes());
encryptedData = Base64.getEncoder().encodeToString(encrypted);
} catch (Exception ex) {
ex.printStackTrace();
encryptedData = null;
}
return encryptedData;
}
}
This is what I have tried.
function SecurityFunc(request) {
const digest = 'SHA256';
var secretkey = 'fgbnhgfcjhgfcvjkhgfcvjkhgfcvbjbnvcjhnbvcfghjnbvc'; // 256 character
var iv = Buffer.from(secretkey.substring(0,16), 'utf-8', 'aes');
const key = crypto.pbkdf2Sync(secretkey, 'boooooo!!', 65536, 32, digest);
const cipher = crypto.createCipheriv('aes-256-cbc', key, iv);
let encrypted = cipher.update(`${request}`, 'ascii', 'base64');
encrypted += cipher.final('base64');
return encrypted;
}
I have searched a lot about this. I got these questions on stack overflow
Difference in key lengths between crypto.pbkdf2 (node.js) and PBEKeySpec, AES/CBC/PKCS5PADDING IV - Decryption in NodeJs (Encrypted in Java) I have tried both of them but none of them resolved my query.
Any help will be highly appreciated.

Are you trying to make the 2 compatible or just port the code from Java to JavaScript?
Update: apparently PKCS#5 will work the same as for PKCS#7 so that isn't your issue.
The key length should be 32-bytes in both cases.
If you don't need backwards compatibility, I'd recommend using AES in GCM mode rather than CBC as it includes tamper protection.

How do I encrypt string in nodejs with public generated by java

I want to encrypt my password in angular side before sending it to Springboot API. My idea is to do:-
Generate public key and private key in java
Do a base64 encoding on both public key and private key
Use encoded public key in node (angular) side, this will be used for encryption
Use encoded private key in springboot rest api, this will be used for decryption
Below is my java code which generates, encrypts and decrypts password

In the Nodejs side I am using the above public to encrypt my text.
index.js
const crypto = require("crypto");
var pubkey = "-----BEGIN PUBLIC KEY-----\nMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDL/rfg+v+2WOpvgow/ezQffPT9mI5hnBNsh1KJMo5sVYv0sSLvTG6IlTXsEfphY0xWDxoDFh89f13lRpYp4zf+ftH3YjvyRLxFIpRZpJCBdzMtdSNPW/TWfUSZqQjQm6joOzUrelQ/CAv8NfTduccHKH3N6m4HxIykrNAoMX2oawIDAQAB\n-----END PUBLIC KEY-----";
var plaintext = "Test"
var buffer = new Buffer.from(plaintext, "utf8");
var enc = crypto.publicEncrypt(pubkey, buffer);
var bs64 = enc.toString('base64');
console.log(enc.toString());
console.log(enc.toString('base64'));
this gives me following output

Now I tried using both the strings in java side for decryption.
When I try decoding the string, it gives me following error
Exception in thread "main" javax.crypto.IllegalBlockSizeException: Data must not be longer than 128 bytes
at com.sun.crypto.provider.RSACipher.doFinal(RSACipher.java:346)

at javax.crypto.Cipher.doFinal(Cipher.java:2168)
at com.mindtree.starr.wsr.RSAKeyPairGenerator.main(RSAKeyPairGenerator.java:90)
And, when I try decoding the base64 string, it gie me following error
Exception in thread "main" javax.crypto.BadPaddingException: Decryption error
at sun.security.rsa.RSAPadding.unpadV15(RSAPadding.java:379)

What am I doing wrong?

The problem was clearly described in the first comment and the solution is in second comment.
Correct transformation string for Cipher instance that worked for me is RSA/ECB/OAEPWithSHA-1AndMGF1Padding
So below instantiation for decryption Cipher works perfectly.
Cipher decryptCipher = Cipher.getInstance("RSA/ECB/OAEPWithSHA-1AndMGF1Padding");

Encryption in Java using "AES/CFB/NoPadding" and decryption in Python using AES.MODE_CFB produce different results

In Java, the code below can encrypt strings of any length and decrypt without any problem.
Java code:
import javax.crypto.BadPaddingException;
import javax.crypto.Cipher;
import javax.crypto.IllegalBlockSizeException;
import javax.crypto.NoSuchPaddingException;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import java.nio.charset.StandardCharsets;
import java.security.InvalidAlgorithmParameterException;
import java.security.InvalidKeyException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
public class AesEncryption {
public static void main(String[] args) throws NoSuchAlgorithmException, IllegalBlockSizeException, InvalidKeyException, BadPaddingException, InvalidAlgorithmParameterException, NoSuchPaddingException {
AesEncryption ae = new AesEncryption();
byte[] secret = ae.encrypt("Hello World!");
for (byte b : secret)
System.out.print(String.format("%d, ", b));
System.out.print("\n");
System.out.print(String.format("%s\n", ae.decrypt(secret)));
}
private final IvParameterSpec iv;
private final SecretKeySpec keySpec;
public AesEncryption() throws NoSuchAlgorithmException {
byte[] key = "thisisasecretkey".getBytes(StandardCharsets.UTF_8);
MessageDigest md = MessageDigest.getInstance("MD5");
md.update(key);
this.iv = new IvParameterSpec(md.digest());
this.keySpec = new SecretKeySpec(key, "AES");
}
public byte[] encrypt(String content) throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidAlgorithmParameterException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException {
Cipher cipher = Cipher.getInstance("AES/CFB/NoPadding");
cipher.init(Cipher.ENCRYPT_MODE, this.keySpec, this.iv);
return cipher.doFinal(content.getBytes());
}
public String decrypt(byte[] secret) throws InvalidAlgorithmParameterException, InvalidKeyException, NoSuchPaddingException, NoSuchAlgorithmException, BadPaddingException, IllegalBlockSizeException {
Cipher cipher = Cipher.getInstance("AES/CFB/NoPadding");
cipher.init(Cipher.DECRYPT_MODE, this.keySpec, this.iv);
return new String(cipher.doFinal(secret));
}
}
Python code:
import array
import hashlib
from Crypto.Cipher import AES
class AesEncryption:
def __init__(self):
key = 'thisisasecretkey'.encode('UTF-8')
md = hashlib.md5()
md.update(key)
iv = md.digest()
self.__cryptor = AES.new(key, AES.MODE_CFB, iv, segment_size=128)
def encrypt(self, content):
return self.__cryptor.encrypt(AesEncryption.r_pad(content.encode('UTF-8')))[:len(content.encode('UTF-8'))]
def decrypt(self, secret):
return self.__cryptor.decrypt(secret)
#staticmethod
def r_pad(payload):
length = 16 - (len(payload) % 16)
return payload + (chr(length) * length).encode('UTF-8')
if __name__ == '__main__':
secretstr = array.array('b', [-108, 20, -91, -103, 13, 59, 94, -51, 17, -104, -30, -83]).tostring()
ae = AesEncryption()
print(ae.decrypt(secretstr).decode('UTF-8'))
However when I pass the secret byte array produced by the Java code to PyCrypto, the decryption fails. The Python code uses AES.MODE_CFB and segment_size = 128 to match the AES mode in Java, but the length of the plain text won't meet the 16-byte-block requirement. Changing the segment_size never produces the same result either. So I figure NoPadding may be the problem. What is the algorithm used by AES/CFB/NoPadding mode in Java? And how is it different from the algorithm used in PyCrypto? Thanks.
Edit:
Thanks to Topaco and Robert. As a stream cipher, CFB mode with segment_size=128 should work correctly. The problem is caused by the bug in an outdated version of PyCrypto. Use latest PyCryptodome instead.

Where is the IV in Triple DES?

I'm encrypt data using triple DES. It works fine, but I have a question.
Where can I see the initialization vector (IV)?
It's 3des encyption with BASE64Decoder.
import java.io.IOException;
import java.io.UnsupportedEncodingException;

this.ecipher = Cipher.getInstance("DESede");
this.dcipher = Cipher.getInstance("DESede");
this.ecipher.init(1, getSecretKey(as_Phrase));
this.dcipher.init(2, getSecretKey(as_Phrase));
}
public String encrypt(String as_valueToEncrypt)
throws BadPaddingException, IllegalBlockSizeException, UnsupportedEncodingException, IOException {
byte[] lbarr_utf8 = as_valueToEncrypt.getBytes("UTF8");
byte[] lbarr_enc = this.ecipher.doFinal(lbarr_utf8);
return new BASE64Encoder().encode(lbarr_enc);
}
public String decrypt(String as_valueToDecrypt)
throws BadPaddingException, IllegalBlockSizeException, UnsupportedEncodingException, IOException {
byte[] lbarr_enc = new BASE64Decoder().decodeBuffer(as_valueToDecrypt);
byte[] lbarr_utf8 = this.dcipher.doFinal(lbarr_enc);
return new String(lbarr_utf8, "UTF8");
}
private SecretKey getSecretKey(String as_Phrase)
throws UnsupportedEncodingException {
return new SecretKeySpec(as_Phrase.getBytes("UTF8"), "DESede");
}
}

You can get the IV from the cipher:
ecipher.getIV();
The problem is that the IV is generated during init. Since you init in the constructor you would run into the problem of using the same IV for every encryption of different ciphertexts. It's always best to generate a new Cipher and init it for every encryption and decryption operation separately.
You use the DESede cipher which is actually DESede/ECB/PKCS5Padding. Note that the mode is ECB which doesn't use an IV. So the above call returns null. Although this is the default mode, it is not recommended. It's safer to use DESede/CBC/PKCS5Padding which actually uses an IV.
So when you decrypt in CBC mode you need to pass that IV in:
dcipher.init(2, new SecretKeySpec(key, "DESede"), new IvParameterSpec(ecipher.getIV()));
To reduce the burden of passing the IV around you could then append the IV to the front of the ciphertext before encoding it and slice it off before decrypting the ciphertext. DES is a 64-bit cipher so your IV will be 8 bytes long.

Cipher has getIV() method, which returns initialization vector.

TripleDes Perl<->Java (CCBill implementation)

I ran into a problem when trying to integrate with a payment processor (CCBill) who is requesting a string to be encrypted to be used as a token, using the TripleDES standard. My application is in Java, and the result I am getting back is not what the payment processor expects.
There is a post here that is addressing Perl<->PHP and Perl<->ColdFusion, but no solutions for Java.
The PERL version of the code looks like this:
#!/usr/bin/perl
# Perl Crypt Calamity (here be...something)
use strict;
use CGI;
use MIME::Base64;
use Crypt::TripleDES;
my $cgi = CGI->new();
my $param = $cgi->Vars();
$param->{key} = "bC5PEcLzvb+jY1FZWuP4pw50";
$param->{string} = "subscriptionId=0214288302000000207";
my $des = Crypt::TripleDES->new();
my $enc = $des->encrypt3($param->{string}, $param->{key});
$enc = encode_base64($enc);
$enc =~ s/\n//gs;
# resulting string (enc): yvT6h6jti9krth/BaA3cO3ABKult8N38fnEb24MS0BwnX+gc1NNgEA==
This is my little Java class trying to do the same as the perl script, but which returns a completely different value:
import java.util.Arrays;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.DESedeKeySpec;
import org.apache.commons.codec.binary.Base64;
public class Encoder {
public String encrypt(String message, String encryptionKey) throws Exception {
// handle the key
SecretKey secretKey = null;
byte[] keyValueAsBytes = Arrays.copyOf(encryptionKey.getBytes("UTF-8"), 24);
DESedeKeySpec keySpec = new DESedeKeySpec(keyValueAsBytes);
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DESede");
secretKey = keyFactory.generateSecret(keySpec);
// cipher
Cipher cipher = Cipher.getInstance("DESede/ECB/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, secretKey);
// encode
byte[] plainText = message.getBytes("UTF-8");
byte[] encryptedText = cipher.doFinal(plainText);
return Base64.encodeBase64String(encryptedText);
}
public static void main(String[] args) throws Exception{
String secretKey = "bC5PEcLzvb+jY1FZWuP4pw50";
String message = "subscriptionId=0214288302000000207";
Encoder enc = new Encoder();
System.out.println(enc.encrypt(message, secretKey));
//returns:hw6JzwdvmjwORzmitXcQ6vsmskK6vtdIObu+KYiGW4D4DRwNGHEX2w==
}
}
Any suggestions and help would be much appreciated.
