Hides secrets inside text by compressing and encrypting the secret before cloaking it with special unicode invisible characters. It can be used to safely watermark strings, invisible scripts on webpages, texts on social media, or for any other covert communication. Completely invisible!
Inspired by the original javascript stegcloak.
This is incompatible with the original js stegcloak. But it can compile to wasm with the
wasm
feature.
Also available on the web @ https://molotovcherry.github.io/stegcloak/
- Allows you to invisibly hide your secret inside regular text
- Protect your secret with password and HMAC integrity
- Encrypts your secret with AES-256-CTR
- Uses 6 invisible unicode characters that work in many places such as Gmail, WhatsApp, Telegram, Facebook, and more!
- Uses compression to minimize size of payload.
- Wasm compatible
- Fastπ¦!
- Can hide the entire wikipedia source in ~201468 characters taking ~3.5ms in plaintext mode and ~7ms in encrypt mode
- Can reveal the entire wikipedia source in ~1.3ms in plaintext mode and ~5ms in encrypted mode
wasm
- If you need wasm support, this feature's for you!
stegcloak-wasm
- This is a pure binding crate to use this purely from javascript. If you want to use stegcloak
in your wasm app, use the normal stegcloak
crate with the wasm
feature
This is currently under dev. Algorithm may be changed at any time, and previously encoded messages may no longer be compatible with the new version.
Every effort has been made to be cryptographically secure, however, this should not be relied on for any sensitive or secure communications! Author absolves self from all possible issues that could arise from usage of this software.
StegCloak doesn't solve the Alice-Bob-Warden problem, it's powerful only when people are not looking for it and it helps you achieve that really well, given its invisible properties around the web! It could be safely used for watermarking in forums, invisible tweets, social media etc. Please don't use it when you know there's someone who is actively sniffing your data - looking at the unicode characters through a data analysis tool. In that case, even though the secret encoded cannot be deciphered, the fact lies that the Warden (middle-man) knows some secret communication took place, because he would have noticed an unusual amount of special invisible characters.
