blowfish

问题 I can't seem to find a source for the differences. I've found this difference in this online decryption tool http://www.tools4noobs.com/online_tools/decrypt/ I have some encrypted Blowfish data that I'm trying to decrypt through Python's PyCrypto module. The problem, however, is that the data seems to be encrypted with "blowfish-compat", as that's what it takes to decrypt it through the online tool; I can't decrypt it through PyCrypto's module, and I'm gathering that it uses strictly Blowfish

问题 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

问题 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

问题 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. 回答1: 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

问题 I need to read a file as binary data, then be able encrypt and decrypt it. I am testing speeds of different algorithms in Crypto++. Up until now, I have been using getline to read text files. int main( int argc, char* argv[] ) { string plaintext, ciphertext, encoded, recovered, sample_files_path, data_file, line_contents, file_size; ifstream initial_file_contents ( "1MB.txt"); if (initial_file_contents.is_open()) { plaintext = ""; while ( getline( initial_file_contents, line_contents ) ) {

问题 I have a Coldfusion page that includes a section of code that encrypts a variable like this: <cfset data64 = toBase64(key)> <cfset encryptedID = encrypt(getUser.ID, data64, "BLOWFISH", "Base64")> We're moving the site to a .NET-based CMS, and I need to convert this page to C#, but I'm running into trouble. I've successfully converted the first line to this: byte[] keyBytes = System.Text.Encoding.UTF8.GetBytes(key); string keyBase64 = System.Convert.ToBase64String(keyBytes); I've also added

问题 What is the difference between PASSWORD_DEFAULT and PASSWORD_BCRYPT? Do they both use Blowfish encryption algorithm? What is cost in an algorithm? How to set up password_hash in PHP produce a 255-hash length instead of 60? 回答1: Currently PASSWORD_BCRYPT is the only algorithm supported (using CRYPT_BLWFISH), therefore there is currently no difference between PASSWORD_DEFAULT and PASSWORD_BCRYPT . The purpose of PASSWORD_DEFAULT is to allow for the inclusion of additional algorithms in the

问题 A legacy application (ColdFusion) is using Blowfish/CBC/PKCS5Padding encryption. How can we encrypt and decrypt this data using the BouncyCastle lib? For other fields, encrypted in ColdFusion using this: encrypt( data, key, 'BLOWFISH', 'HEX') We use this code BlowfishEngine engine = new BlowfishEngine(); PaddedBufferedBlockCipher cipher = new PaddedBufferedBlockCipher(engine); cipher.Init(false, new KeyParameter(Convert.FromBase64String(keyString))); byte[] out1 = Hex.Decode(name); byte[]
