3des

问题 Please, just don't ask me why. I just have this code in .NET that encrypt/decrypt strings of data. I need now to make 'exactly' the same funcionality in java. I have tried several examples for DESede crypt, but none of them gives the same results as this class in .net. I even though on making a .net webserbvice behind ssl to serve this two methods writen in .net but it is just too stupid to do without exhausting all the posibilities. Maybe some of you java people which are more related in the

问题 Am trying to decrypt a key encrypted by Java Triple DES function using PHP mcrypt function but with no luck. Find below the java code import javax.crypto.Cipher; import javax.crypto.spec.IvParameterSpec; import javax.crypto.spec.SecretKeySpec; public class Encrypt3DES { private byte[] key; private byte[] initializationVector; public Encrypt3DES(){ } public String encryptText(String plainText, String key) throws Exception{ //---- Use specified 3DES key and IV from other source --------------

问题 I'm new to encryption. I need to implement asymmetric encryption algorithm, which i think it uses private/public key. I started using a sample of RSACryptoServiceProvider. it was ok with small data to encrypt. But when using it on relatively larger data "2 lines", i get the exception CryptographicException "Bad Length"! //Create a new instance of RSACryptoServiceProvider. using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider()) { //Import the RSA Key information. This only needs

问题 I have a two mails (SMIME encrypted) for a single recipient. One mail is encrypted using 3DES, the other one is encrypted using AES 256. The mails where created using C# EnvelopedCms class. I can successfully decrypt the 3DES message using openssl smime -decrypt -in trippledes.eml -inkey keyfile.pem However, if I try this with the AES encrypted file, OpenSSL outputs some gibberish and Fails with this comment: Error decrypting PKCS#7 structure 4128:error:06065064:digital envelope routines:EVP

问题 I have to decrypt in PHP a string encoded with this C# class (it's here) using System; using System.Security.Cryptography; using System.Text; public static class Encryption { public static string Encrypt(string input, string key) { byte[] inputArray = UTF8Encoding.UTF8.GetBytes(input); TripleDESCryptoServiceProvider tripleDES = new TripleDESCryptoServiceProvider(); tripleDES.Key = UTF8Encoding.UTF8.GetBytes(key); tripleDES.Mode = CipherMode.ECB; tripleDES.Padding = PaddingMode.PKCS7;

问题 I am trying to use the mycrypt php library to decrypt the following: Key: aaaaaaaabbbbbbbbccccccccdddddddd Data: b5057bbc04b842a96144a0f617f2820e Expected Result: Test123123 The data is encrypted with 3DES with the mode ECB. The code I'm currently working with decrypts the hex value to "e2119b734b5050e3" which translates to "â›sKPPã". I have tried using open ssl which is returning "False". The code is as follows: (PHP Version 5.3.3) $key = 'aaaaaaaabbbbbbbbccccccccdddddddd'; $key = pack('H*',

问题 I've been trying for many days to try and solve this issue. A 3rd Party webservice requires me to send encrypted data using 3DES with ECB and PKCS7padding - They're using .NET The encrypt function within railo CFML is limited to DESede without any further options (i.e. defaults are used for cipher mode and padding). Has anyone had this issue in Railo and come up with a solution (java based perhaps)? - I'm seriously pulling my hair out here! Based on Leigh's suggestions below I made some

问题 I'm trying to exchange encrypted data between my ASP.NET application and another developer's CF app using TripleDES. Here's his CF code (fictitious key and IV of course): <cfset variables.theKey = "rpaSPvIvVLlrcmtzPU9/c67Gkj7yL1S5"> <cfset variables.theIV = BinaryDecode("password","Base64")> <cfset variables.theAlgorithm = "DESEDE"> <cfset variables.theEncoding = "Base64"> <cfif IsDefined("form.string") and IsDefined("form.method")> <cfif form.method is "encrypt"> <cfset variables.theString =

问题 We would like to convert our use of mcrypt to openssl. Here is our encryption function: mcrypt_ecb(MCRYPT_3DES,$key,$payload,MCRYPT_ENCRYPT) Here is our decryption function: mcrypt_ecb(MCRYPT_3DES,$key,$payload,MCRYPT_DECRYPT) What are the openssl_* equivalents of the above? Thanks. 回答1: I think you're looking for the EVP_Encrypt... functions with EVP_des_ede3 as the cipher (although you should really be using CBC mode rather than ECB). https://www.openssl.org/docs/crypto/EVP_EncryptInit.html

问题 System.Security.Cryptography.TripleDES allow me use zero padding like this : static TripleDES CreateTripleDES(byte[] key, byte[] iv) { TripleDES des = new TripleDESCryptoServiceProvider(); des.Key = key; des.IV = iv; des.Mode = CipherMode.CBC; des.Padding = PaddingMode.Zeros; return des; } Now change to use OpenSSL CipherContext cc = new CipherContext(Cipher.DES_EDE3_CBC); byte[] des3 = cc.Encrypt(msg2, tripleKey, tripleIv, 0); //public byte[] Encrypt(byte[] input, byte[] key, byte[] iv, int
