Hi so lets assume that client-side has a key that is not transfered via the same channel as the encrypted data.
What I am trying to accomplish is to decrypt the result of Stanford Javascript Crypto Library (sjcl) in ruby. or for a generalisation in any other language that has a crypto library that has support for AES.
Here is what I am doing in javascript:
sjcl.encrypt('stack-password', 'overflow-secret')
And this is what I get in return:
{"iv": "Tbn0mZxQcroWnq4g/Pm+Gg","v": 1,"iter": 1000,"ks": 128,"ts": 64,"mode": "ccm","adata": "","cipher": "aes","salt": "pMQh7m9Scds","ct": "H6JRpgSdEzKUw2qEO1+HwIzAdxGTgh0"}
So what I'm actually asking is, which of these parameters I need(assuming the server already has the "stack-password" key) in order to decrypt the secret server-side, and which library should I use?May be having AES decryption library is not enough?
