I'm interested in building a small app for personal use that will encrypt and decrypt information on the client side using JavaScript. The encrypted information will be stored in a database on a s...

Apr 27, 2009 · How can I encrypt data with AES 256-bit encryption in JavaScript?

Jan 17, 2020 · I'm looking to get a SHA256 hash in JavaScript, on Google Chrome 79.0.3945.130 (64-bit). I've been looking around thinking there would be some sort of official library or function, but all I found ...

Sep 3, 2022 · You could use the Crypto API Crypto.subtle which returns a SubtleCrypto object providing access to common cryptographic primitives, like hashing, signing, encryption, or decryption. Then you can use every method in SubtleCryptography such as encrypt and decrypt.

Apr 25, 2011 · I'd recommend using AES encryption in your JavaScript code. See Javascript AES encryption for libraries and links. The trouble you'll have is picking a key that is only available on the client side. Perhaps you can prompt the user? Or hash together some client system information that's not sent to the server.

Dec 23, 2010 · Then on the client-side it will be decrypted through Javascript code. Any thoughts on how to implement this? Do you know of a simple encryption algorithm (doesn't have to be bullet-proof secure) that can be easily translated from C# to Javascript or vice-versa?

The Javascript code is executed in the browser, i.e. on the client side, which means it must be available not-encrypted on the client side. The "best" you can do is probably to minify it, which will make it harder to understand it -- and a bit of obfuscation might do too -- even if someone really motivated will still be able to read it.

I'd like to generate a public/private keypair in javascript, and use the public key to encrypt message and the private key to decrypt the message. I prefer native browser support over external lib...

Jan 16, 2017 · I need to implement AES encryption using JavaScript. Used AES/CBC/NoPadding Mode and created a method to complete 16 lenght blocks. I already solved it using Java. It looks like: public static Str...

I have been instructed to write an application that takes some data then encrypts it with an RSA public key. It needs to be "RSA encryption": Which encryption cipher is RSA meant to use as
