hat.sh - Encrypt and Decrypt files securely in your browser.

•    Javascript

---

Hat.sh is a web app that provides secure file encryption in the browser. It's fast, secure and runs locally, the app never uploads the files to the server. It uses modern secure cryptographic algorithms with chunked AEAD stream encryption/decryption. The libsodium library is used for all cryptographic algorithms.

libsodium-xchacha20-siv - Deterministic/nonce-reuse resistant authenticated encryption scheme using XChaCha20, implemented on libsodium

•    C

---

Deterministic/nonce-reuse resistant authenticated encryption scheme using XChaCha20, implemented on libsodium. Encrypt a message m of length mlen bytes using a key k, an optional nonce nonce (which can left to NULL), optionally authenticating additional data ad (if not NULL) of length adlen bytes in addition to the message itself. The IV acting as a MAC is stored into mac.

A MessageType for a custom channel may be created via function MessageTypeChannel(channelID uint32). channelID is a custom number to identify which flow is it (to connect a sender with appropriate receiver on the remote side). In the examples above it was used 0 as the channelID value, but it could be any value in the range: 0 <= x <= 2**31. Also there's a special MessageType MessageTypeReadWrite is used for default Read()/Write(). But you may redirect this flow to a custom handler.
