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 Am trying to send data to an external api that expects encrypted data using 3DES encryption but am having issues understanding how to pass my api key as the key field to erlangs des_ede3 cipher. According to erlangs cipher docs des_ede3 expects 3 keys that are all 8 bytes in length. How can i pass my 24 byte api key as the key to elixir/erlang :cryptoblock_encrypt/4 function *** how can i pass key to block_encrypt/4 *** key = "123456789012345678901234" data = "hello world! The world is yours"

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 have the following code for encrypting the request i am sending to my server. The decoding on the server is done by .NET and on the iPhone, I am using the security framework with the following code. - (NSString*) doCipher:(NSString*)plainText:(CCOperation)encryptOrDecrypt { const void *vplainText; size_t plainTextBufferSize; if (encryptOrDecrypt == kCCDecrypt) { NSData *EncryptData = [[NSData alloc] initWithBase64EncodedString:plainText]; plainTextBufferSize = [EncryptData length];

问题 For `BDK = "0123456789ABCDEFFEDCBA9876543210"` `KSN = "FFFF9876543210E00008"` The ciphertext generated was below "C25C1D1197D31CAA87285D59A892047426D9182EC11353C051ADD6D0F072A6CB3436560B3071FC1FD11D9F7E74886742D9BEE0CFD1EA1064C213BB55278B2F12"` which I found here. I know this cipher-text is based on BDK and KSN but how this 128 length cipher text was generated? What are steps involved in it or algorithm used for this? Could someone explain in simple steps. I found it hard to understand the

问题 We are having difficulty decrypting a string in ColdFusion that was previously encrypted with 3DES and C#. Here is the code we used to encrypt the string initially: public static string EncryptTripleDES(string plaintext, string key) { TripleDESCryptoServiceProvider DES = new TripleDESCryptoServiceProvider(); MD5CryptoServiceProvider hashMD5 = new MD5CryptoServiceProvider(); DES.Key = hashMD5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(key)); DES.Mode = CipherMode.ECB; ICryptoTransform DESEncrypt

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 10 months ago . I need a way to encrypt and decrypt with 3des. I'm currently using php 7.1 I found this question, but mcrypt is deprecated as of php 7.1 and I can't find any other resource for this. 回答1: Continue to the Comments section of the function's manual and you'll see the following: If
