tripledes

问题 I mostly work with PHP, but I'm sending data to an api that's using C# for encryption, so I'm trying to encrypt a password in PHP, using the same method used in the following C# code: System.Security.Cryptography.TripleDESCryptoServiceProvider DES = new System.Security.Cryptography.TripleDESCryptoServiceProvider(); System.Security.Cryptography.MD5CryptoServiceProvider hashMD5 = new System.Security.Cryptography.MD5CryptoServiceProvider(); DES.Key = hashMD5.ComputeHash(System.Text.ASCIIEncoding

问题 I have a set of encrypted documents encoded with TripleDES coming from a remote system. I need to decode the data in C# and I have no control over the key or encoding algorithm. All I have is the key and the mode (CBC) and the data located in a file. The TripleDESCryptoServiceProvider is easy enough to use, but I can't figure out how to use the Decryptor without an Initialization Vector. We have a have 24 byte (192bit) key to decrypt with, but nothing else. string key =

问题 I am trying to recreate some openssl php code in the command-line. I have been able to get the following php code to work: $key = 'aaaaaaaabbbbbbbbccccccccdddddddd'; $key = pack('H*',$key); $data = 'b5057bbc04b842a96144a0f617f2820e'; $data = pack('H*',$data); $result = openssl_decrypt($data,'des-ede', $key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING); The Command I'm Working on (Ubuntu) openssl des-ede -in encrypted-data.txt -out decrypted-data.txt -d -K aaaaaaaabbbbbbbbccccccccdddddddd -nopad

问题 I have to encrypt a hex string with two keys. My code for this looks like that: public byte[] TripleDes(byte[] inputBuffer, byte[] key) { byte[] result; using (TripleDESCryptoServiceProvider des = new TripleDESCryptoServiceProvider()) using (MemoryStream stream = new MemoryStream()) using (CryptoStream cryptoStream = new CryptoStream(stream, des.CreateEncryptor(), CryptoStreamMode.Write)) { des.Key = key; // des.KeySize = 128; <- wrong, overrides the values of the key des.Mode = CipherMode

问题 I am porting some C# code to C++, and trying to encrypt a textfile with Triple DES encryption. But I am confused; some encryption APIs only require one key for Triple DES (C# for example: How to implement Triple DES in C# (complete example) ), while others require 2 or 3 keys (in several C++ implementations I've found). Why is that? 回答1: The TDEA keying is maybe better understood here considering the key length over just a simple key. Depending on the keying option used, it can be a single

问题 In order to write an simple nodejs app talking to an server written in java I have to implement the following functionality for nodejs. public class Crypto { Cipher decipher; byte[] salt = { (byte) 0x01, (byte) 0x02, (byte) 0x03, (byte) 0x04, (byte) 0x0A, (byte) 0x0B, (byte) 0x0C, (byte) 0x0D }; int iterationCount = 10; public Crypto(String pass) { try { KeySpec keySpec = new PBEKeySpec(pass.toCharArray(), salt, iterationCount); SecretKey key = SecretKeyFactory.getInstance(

问题 i had to receive some data encrypted with 3DES with shared keys. I'm using php7 and openssl_decrypt function, but I'm not able to recreate the result of the example of the documentation sent to me. The OpenSSL command that create the data sent to me is the following: openssl enc -des-ede3-cbc -base64 -K 17839778773fadde0066e4578710928988398877bb123789 -iv 00000000 -in D:/in.txt Example: string_encoded: 123456 data_to_decrypt: Ja79hWTRfBE= I tried to decode "Ja79hWTRfBE=" with an online tool

问题 I’m working on a mvc application over .Net, to secure my sensitive information such as info in web.config I’ve got two functions that encrypts and decrypts information using Triple DES, however I’m new to this and succeeded to reach till here by the help of a friend and asking few question over here. The point where I’m currently stuck is how can I add TDES IV (Initialization Vector) at the end of the encrypted string and how also retrieve it again while decrypting? I mean how would you

问题 I'm doing tripleDES encryption and decryption. Getting this error: UnsafePointer<UInt8>' is not convertible to 'UnsafePointer<_> The code where I'm getting the error is: let keyString = "25d1d4cb0a08403e2acbcbe0" let keyData = keyString.data(using: .utf8)! let message = pass let data = message.data(using: .utf8)! let cryptData = NSMutableData(length: Int(data.count) + kCCBlockSize3DES)! let keyLength = size_t(kCCKeySize3DES) let operation: CCOperation = UInt32(kCCEncrypt) let algoritm:
