encryption

问题 I need to verify the signed data. I dont know how to use the public key. public bool VerifyData(string data, string signature) { //decode signature from base 64 byte[] signatureByte = System.Convert.FromBase64String(signature); //hash data to sha256 string hashedData = ConvertToSHA256(data); byte[] hashedDataByte = System.Convert.FromBase64String(hashedData); //verify with RSA PSS string absPath = System.Web.Hosting.HostingEnvironment.MapPath("~/App_Data/TP/public"); string publicKeyString =

问题 In my Andorid app, am using few keys and tokens for authentication and initialisations. I need to store these static keys somewhere in app securely. At the same time, I need to access it in code as well. I am aware of SharedPreference and Gradle variables, which right now I use. I have tried Cryptography as well, but then I will have to store the secretKey also for decryption. So, am searching for any workaround or proper solution. Any help will be highly appreciated. 回答1: YOUR PROBLEM Where

问题 I'm facing a issue now which need you guys help. I use c# to do some encryption. Then need to use node.js to decry-pt it. But I just found that I can't do it correctly base on my c# encryption algorithm. If you guys have any solution, please help me. Here is my c# encryption code: public static string Encrypt(string text, String password, string salt, string hashAlgorithm, int passwordIterations, string initialVector, int keySize) { if (string.IsNullOrEmpty(text)) return ""; var

问题 I'm fairly new to coding, this is one of my first bigger Python projects that I'm working on and I have a problem with Adyen payment submission. I'm trying to make a payment on a website that uses an Adyen payment gateway. Adyen encrypts your payment data client side and only accepts encrypted requests otherwise they'll throw back a 400 bad request and the payment will not go through. I'm stuck when it comes to ideas, I analyzed the traffic in Charles when I'm making a payment manually -

问题 Help me to make encryption AES/CBC/PKCS7Padding ? Below is my code to decrypt AES/CBC/PKCS7 . It's working but when I encrypt some string and decrypt from my self it's error. Below i adding code to encrypt and decrypt AES/CBC/PKCS7Padding. - (NSData *)AES256Encrypt:(id)key { NSString *iv = @"FEDCBA9876543210"; NSData *keyPtr = [key copy]; size_t dataLength = [self length]; NSData *ivPtr = [iv dataUsingEncoding:NSUTF8StringEncoding]; //NSData *encrypted = [self subdataWithRange:NSMakeRange(0,

问题 I am using AndroidKeystore to generate RSA Keypair and doing encryption and decryption using this keypair My keypair generation code looks like this var keypairGen:KeyPairGenerator = KeyPairGenerator.getInstance(KeyProperties.KEY_ALGORITHM_RSA, "AndroidKeyStore") var keyPairGeneratorSpec: KeyGenParameterSpec = KeyGenParameterSpec .Builder(this.Key_Name, KeyProperties.PURPOSE_ENCRYPT or KeyProperties.PURPOSE_DECRYPT) .setDigests(KeyProperties.DIGEST_SHA256, KeyProperties.DIGEST_SHA512)

问题 I'm planning to encrypt the connection strings of a web configuration file belonging to an application which will be run in a server farm. I am aware of the aspnet_regiis command line tool to encrypt the sections using it. But I have some doubts, which I expect you guys can solve. My question is that if I encrypt the connectionstrings and the web.config file is stolen by some hacker, will he be able to decrypt it using the same command line with -pe switch? The same is shown below. My Servers
