encryption

问题 I have searched lot before posting this question. Earlier the code was working in non android 4.2/2.1 devices. Then i googled and introduced the below lines of code. That solved it partially,ie it's now working on 4.2 devices but not on Froyo. if (android.os.Build.VERSION.SDK_INT >= JELLY_BEAN_4_2) { sr = SecureRandom.getInstance("SHA1PRNG", "Crypto"); } else { sr = SecureRandom.getInstance("SHA1PRNG"); } The below given is the class I use for encryption public class Encryption { private

问题 I've been looking at articles online about solutions to encrypting id's in a url. I've tried the basic encode decode but the problem i'm having when decoding it on the next page where I do a select where id = decoded id. It won't grab the proper user still from the table. My link: My link: <a href="sendContract.inc.php?id=<?php echo encrypt($customer_id) ?>"> View Contract </a> sendContract.inc.php page: $customer_id = $_GET['id']; $decryped_id = base64_decode($customer_id); $sql = "SELECT *

问题 I'm working on implementing a public key encryption from PyCryptodome on Python 3.6. When I try to create a symmetric encryption key and encrypt/decrypt variables, it all works fine. But the minute I introduce RSA (and PKCS1_OAEP), it all goes down the tubes - the session_key encrypts fine but when I try and decrypt it, I get the following error: Traceback (most recent call last): File "enctest.py", line 109, in <module> deckey = decrypt_val(enckey) File "enctest.py", line 77, in decrypt_val

问题 I want to generate a 256bit password for my AES encryption. When I check the password after the encryption it is different from my initial password. What am I doing wrong? Or is there some security mechanism I am not aware of? My code: password=Generate_key(); var encrypted = CryptoJS.AES.encrypt("Message", password); //Those two should be the same document.write(password+"<br>"); document.write(encrypted.key); function Generate_key() { var key = ""; var hex = "0123456789abcdef"; for (i = 0;

问题 Is there any way (in built or add-on) to encrypt individual files in a repository, accessible by limited people. Files when checked in by those folks will auto encrypt and decrypt when checked out. They will stay encrypted if tried to be accessed by other people. 回答1: I know my answer is late but there is plenty of alternatives for storing secrets in git repos: Git-crypt BlackBox SOPS Transcrypt Most of them use GNU Privacy Guard (GPG), symmetric key encryption, and/or cloud key services

问题 I'm trying to simply encrypt a message using a given key and iV. I've tried several libraries to achieve this but Expo isn't compatible with any of them. I couldn't find any encryption libraries for Expo ( That support AES ). I guess my question is : How do I encrypt data in React Native running Expo Ps : I am not interested in expo-crypto 回答1: Another possibility (what I did) is to use the CryptoES library. https://www.npmjs.com/package/crypto-es After long search I found it, it is a

问题 I have a df with 300 columns but there is one column ID that I want to encrypt and allow anyone else with a key to decrypt if I give them the df as a csv. Is this possible? I know how to hash a column, but as far as I have read I can not unhash it or give someone a key to unhash it. Thank you in advance. edit: df id 1 2 3 @Wen is this a good example: (1:2), (2:3),(3:4) new df id 2 3 4 回答1: I'd recommend the python itsdangerous library. Here is a quick example: from itsdangerous import
