blowfish

I am struggling due to my incomplete knowledge of Java to convert this encryption code to Python code. The two should have the exact same results. Help would be greatly appreciated. Java Function import javax.crypto.Cipher; import javax.crypto.spec.SecretKeySpec; import java.security.Key; class Main { public static void main (String[] args) throws java.lang.Exception { String s = "testings"; Cipher cipher = Cipher.getInstance("Blowfish/ECB/PKCS5Padding"); Key key = new SecretKeySpec("6#26FRL$ZWD".getBytes(), "Blowfish"); cipher.init(1, key); byte[] enc_bytes = cipher.doFinal(s.getBytes());

Here is some example code with altered key values and payload: $key = '/4rTInjwg/H/nA=='; $key = base64_decode($key); $data = 'val=100|val=200|val=300|val=400|val=500|val=600|val=700|val=800|val=900|'; $data.= 'val2=100|val2=200|val2=300|val2=400|val2=500|val2=600|val2=700|val2=800|val2=900|'; $data.= 'val3=100|val3=200|val3=300|val3=400|val3=500|val3=600|val3=700|val3=800|val3=900|'; $data.= 'val4=100|val4=200|val4=300|val4=400|val4=500|val4=600|val4=700|val4=800|val4=900|'; $result = base64_encode(mcrypt_ecb(MCRYPT_BLOWFISH,$key, $data, MCRYPT_ENCRYPT)); This encrypts and decrypts fine in

Hullo, I am encrypting and decrypting in Java with Blowfish. The encryption works fine, but the decryption fails. Here is my Java code for decrypting : String encryptedString = … ; String decryptedString = null; SecretKeySpec key = new SecretKeySpec(myKey.getBytes(), "Blowfish"); Cipher cipher; try { cipher = Cipher.getInstance("Blowfish"); cipher.init(Cipher.DECRYPT_MODE, key); byte[] decrypted = cipher.doFinal(encryptedString.getBytes()); decryptedString = new String(decrypted, Charset.forName("UTF-8")); } [ catch Exceptions … ] I get an exception : Exception. javax.crypto

I am able to encrypt data however when decrypting it i am getting the following error: Error HTTP Status 500 - Request processing failed; nested exception is javax.crypto.IllegalBlockSizeException: Input length must be multiple of 8 when decrypting with padded cipher org.springframework.web.util.NestedServletException: Request processing failed; nested exception is javax.crypto.IllegalBlockSizeException: Input length must be multiple of 8 when decrypting with padded cipher org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:894) org.springframework.web.servlet

I want to encrypt a binary file. My goal is that to prevent anyone to read the file who doesn't have the password. Which is the better solution, AES or Blowfish with the same key length? We can assume that the attacker has great resources (softwares, knowledge, money) for cracking the file. Probably AES. Blowfish was the direct predecessor to Twofish. Twofish was Bruce Schneier's entry into the competition that produced AES. It was judged as inferior to an entry named Rijndael, which was what became AES. Interesting aside: at one point in the competition, all the entrants were asked to give

I am running Crypto++ doing speed tests on encryption algorithms. I am trying to time how long it takes to encrypt, then decrypt the data(eventually with more file sizes and different algorithms). I am running into a problem where I cannot loop over the code. In the following code, I am using Blowfish, but when I get to the encryption part, it gives me the error: HashVerificationFilter: message hash or MAC not valid What can I do to fix this? Do I need to put it in a function? If so, how would I do that? /** * g++ encryption_tests.cpp -o encryption_tests -lcryptopp -lpthread -L. */ #include
