Here is what I am trying to do: I get a file, split that in chunks by reading as arraybuffer then, I parse the arraybuffer as string and passing it to cryptoJS for hash computation using following code: cryptosha256 = CryptoJS.algo.SHA256.create(); cryptosha256.update(text); hash = cryptosha256.finalize(); It all works well for a text file. I get problems when using the code for hashing a non-text files (image/.wmv

My issue: In order to encrypt my message in such a way that the client can decrypt it with crypt-js (using a user entered password), I need to know the exact steps that crypto-js expects while encrypting a message. What I need to know: I have the following encryption code which does the encryption

My knowledge of encryption isn't brilliant but the thing I am noticing is the
