问题 I wanted to verify JWT signature with RS512 algorithm using public key. I fond the exact solution given in the below link and it is working perfectly. Verifying JWT signed with the RS256 algorithm using public key in C# But I want to use System.IdentityModel.Tokens.Jwt with my application. Can anyone change below working example by implementing System.IdentityModel.Tokens.Jwt ? static void Main(string[] args) { var token = "eyJhbGciOiJSUzUxMiIsImtpZCI6ImsxMDY5NDgxOTAifQ

问题 I have an ABAP class which encodes a string as qr code and sends this code as email. At a later point, the code will be decoded by a SAPUI5 app based on JavaScript. I don't want that everyone can decode the string behind that qr code with some basic barcode scanner app. That's why I'm looking for some ideas for encrypting the string in ABAP and decrypting it with JavaScript. Maybe also with a simple algorithm? It's just that the string should not give usable information to someone who decodes

问题 I am working on code that was originally written by a vendor that has gone out of business. It is a classic ASP site and a lot of the server side code looks like the following. I'm wondering if there is a way to decrypt/unscramble it. <%#@~^EgAAAA==@#@&P~,PxN,k6@#@&1AIAAA==^#~@%> 回答1: Do your files begin with <%@ LANGUAGE = VBScript.Encode %> I've inherited files like that before and I decoded them with this http://virtualconspiracy.com/content/scrdec/usage 回答2: UUDECODE & UUENCODE are you

问题 The java code is Cipher c = Cipher.getInstance("AES/CBC/PKCS5Padding"); byte[] ivBytes = new byte[c.getBlockSize()]; String IV = CryptoUtils.hexEncode(ivBytes); It's giving random 16 bytes response like 563ffcecaa43753bd09613095ad24a12. How to write corresponding code into objective c? I have some bunch of objective c code - - (NSData *)createCipher:(NSString*)data WithKey:(NSString*)key { NSData* result = nil; // setup key unsigned char cKey[kCCKeySizeAES256]; // room for terminator (unused)

问题 For security, I encrypted some data, such as username, passwords, and emails in the browser by jsencrypt which is a A Javascript library to perform OpenSSL RSA Encryption, Decryption. And then I decrypt the cipher data using RSACryptoServiceProvider by C#. The public key, and private key are generated by c#： <RSAKeyValue><Modulus>wDIL9/5eXYZB1J6yOQSJTvczV6dv7/mF3X9p+86kWCArYQmNih/Y+ktOboAjo2UyC8np5Y81yF8G/qAdSrreIwdTtZyAFlgpij2Oovmqpg4/mzL7VS6Sj/4y34+GKRczTjDjxuqTmD4F
