问题 I'm decrypting legacy data created by a Ruby on Rails application using the symmetric-encryption gem in Rust. See my earlier question How do I decrypt data encrypted by Ruby's `symmetric-encryption` gem in another language?. I've already implemented this in Node where the crypto library seems to know how to strip out gibberish in an encrypted string that Rust's openssl crate isn't stripping out (at least, the way I'm using it). I have already stripped out the PKCS7 padding and a header, yet

问题 I need to encrypt part of our web.config for our ASP.Net 4.0 project, but we are required to use AES and the default appears to be Triple DES. How can I tell it to use AES encryption instead? In the command prompt I do the following commands: aspnet_regiis -pc "NetFrameworkConfigurationKey" -exp aspnet_regiis -pe "connectionStrings" -app "/<myapp>" I figure I set the encryption method to AES by selecting the appropriate CSP (-csp) but I haven't been able to find or figure out the name of the

Hello Everyone I am trying to build a code to do demonstrate doing AES encryption in assembly. the latest Intel manual has AESENC xmm1,xmm2/m128 —Perform One Round of an AES Encryption Flow round key from the

问题 I am writing android app that makes AES encryption/decryption of files. I want to be able to detect if incorrect password is specified and thus not matching key is derived for decryption. I am using AES/CBC/PKCS7Padding with 256 bit key. If I do cipher.doFinal() I can try/catch the BadPaddingException and it tells me that something is wrong and probably key was incorrect. But if I use CipherInputStream to read encrypted file, I get no feedback on correctness of padding. So if I deliberately

问题 Problem Scenario: I am creating an encrypted file using OpenSSL AES-256-CBC mode in Ubuntu. openssl aes-256-cbc -a -in avengers.txt -out avengers.enc test test File Content: avengersAssemble avengers.enc file content: U2FsdGVkX194TyUFrb4gOn86XYaKjKP98YdOlQDJz+t/76mvVmNKl+NyKKUnYwYH To Decrypt: openssl aes-256-cbc -a -d -in avengers.enc Now I want to decrypt this encrypted file avengers.enc using java code i.e., I just store this file content and password (in this case test) to decrypt it. My

问题 I wanna encrypt my files on PC(Windows 7, 64bit) and decrypt 'em on Android. I use this algo to encrypt files. http://gladman.plushost.co.uk/oldsite/AES/aes-byte-29-08-08.zip I encrypt my files on PC, push them to SDcard. Unfortunately when I try to decrypt them on Android, the result is different, files are completely unreadable...! What's wrong with my code? jbyteArray Java_com_example_hellojni_HelloJni_decrypt(JNIEnv* env, jobject thiz, jstring fileName) { ...... /* read the file into the

问题 In an application in node.js, I am using crypto module for symmetric encryption/decryption. I am using AES-256-CTR. I originally assumed the crypto.createCipher will be "just working" and "handwaved" the details. Now I am reading in the documentation: Note: createCipher derives keys with the OpenSSL function EVP_BytesToKey with the digest algorithm set to MD5, one iteration, and no salt. The lack of salt allows dictionary attacks as the same password always creates the same key. The low

问题 I have a cipher text I encoded with the AesManaged .Net classes. plaintext: "string" password: "password" this is the c# code I use to encrypt: private AesManaged AESCipher; private String Password; public AES(String Password) { this.AESCipher = new AesManaged(); this.AESCipher.Mode = CipherMode.CBC; this.AESCipher.Padding = PaddingMode.PKCS7; this.AESCipher.IV = HexStringToByteArray("000102030405060708090A0B0C0D0E0F"); this.AESCipher.KeySize = 256; this.AESCipher.BlockSize = 128; this

问题 We have an application that uses Bouncy Castle to encrypt data using PBEWITHSHA256AND128BITAES-CBC-BC algorithm. It works fine on Ubuntu running OpenJDK 1.7 . But when when we move it to RedHat 6.4 also running OpenJDK 1.7 , we get the following exception: java.security.NoSuchAlgorithmException Any thoughts on what could be causing this. How can we add PBEWITHSHA256AND128BITAES-CBC-BC algorithm to RedHat 6.4 ? p.s. the application is running in JBoss . private String cryptoAlgorithm =

I have a program that encrypts and decrypts using the AES algorithm, but I have to specify the name of the encrypted file, and also specify the format of the original file as part of the name of the encrypted file. I will like to know how how to implement the following features into my code: I want the name of the encrypted file to be in cipherText I want the
