Hmm, this is an issue. I know this is at odds with what you (and lots of similar designs) are trying to do, but thought it useful to point out, I'd be tempted to use a more conventional protocol for authentication, probably also separating out passwords used for authentication and encryption. Encryption all the way and everywhere. Sure, there is a lot of stuff going on out of the scope of this code and I really appreciate the feedback. We do not. For our activation process we need to be able to send encrypted credentials to server. However, the endpoint has not been verified. 3. At some point in your mobile life, you're going to need to send an encrypted message. Can you escape a grapple during a time stop (without teleporting or similar effects)? Zero correlation of all functions of random variables implying independence. Most email server software allows enforcing encryption for server-to-server communication, meaning Server A will not deliver emails to Server B if Server B doesn’t support encryption. What authority does the Vice President have to mobilize the National Guard? For example, you can encrypt and decrypt files that contain sensitive employee data or confidential documents. Origin of “Good books are the warehouses of ideas”, attributed to H. G. Wells on commemorative £2 coin? Code Review Stack Exchange is a question and answer site for peer programmer code reviews. Server will, in turn, use the same passcode to decrypt the data received from the client. MathJax reference. Every email, between Secure Swiss Data users, is sent encrypted from the user’s device to our server, stored on the server encrypted, and then the email is transmitted encrypted to the end Secure Swiss Data user. On client side, to generate secret key at runtime, encrypt sensitive string using secret key, and encrypt secret key using public key, this class will help you: 3.

"Are you going to search through all password hashes to get to the right one?" I Can only import certificate, if ssl is enabled to sending syslog. Create another Argon2 hash and use it as a key to AES-encrypt the JSON payload (AES-256/CBC/Pkcs). Server-side encryption is data encryption at rest—that is, Amazon S3 encrypts your data as it uploads it and decrypts it for you when you access it. I don't have any experience in cryptography and I've written some crypto code that seem to be working, but I'm not sure if it safe and if the tools and methods I used are right. Server would only know the derived password and not the original one (entered and known by the user). If that's true, you don't need a random IV, because the key would be unique. Instead, you can split the key into two using a KBKDF function such as HKDF (or a poor mans KDF such as using HMAC with the secret as key and an info string as message to distinguish two or more keys). what's the use case for this? Sending Encrypted data between two apps (php, nodejs) with json web tokens. Daniel is a librarian who ran into a vortex of IT world, where he is levitating and learning constantly. Attach IV and random salt to encrypted payload. I'd probably just use the hash of the email as the salt, using password as well doesn't seem to help much. The idea of separating auth and encryption looks interesting. I have also implemented sending small strings of data encrypted with RSA and HTTP. Same password + deterministic salt should give the same hash on any device so server would log it in just fine. As illustrated in the schematic below, the client driver encrypts the data on the client side using the keys only the client knows before sending encrypted data to the database. CBC with PKCS#7 padding is absolutely terrible as it allows for padding oracle attacks. About Daniel Tikvicki. Are you going to search through all password hashes to get to the right one?
