Encrypted messages without history - for when you want to send an api key or password or the like and don't want it sitting in the recipients WhatsApp/Signal history, for example, or going over non-encrypted channels like email or Slack. And you don't want to set up a complicated encryption messaging thing. There are similar services already: e.g. onetimesecret, burnernote - but I wanted something that did encryption client side. I also wanted to set up channels, to send multiple messages between 2 devices without doing "trust on first use" for each new message.

The encryption takes place in the browser - if you're a developer: you can even use browser devtools debugging/network sections to confirm the private key never leaves your device.

I plan to work on the ux, and also further strengthen the encryption (e.g. does the signal protocol work for this...? will implement something that should provide some form of forward secrecy in any case), and make a Flutter-based client so it's super convenient to use on all platforms (maybe also enable things like nfc-based key change...).

Would be very interested to hear from anyone who would like to help! :)



sounds a lot like privatebin.info . it also does the encryption client side. my workplace even selfhost it for our internal usage


Thanks for this! Taking a look. Hope to see self-hosted Oncer.io in the wild one day too :)


This reminds me of Firefox Send.


I did appreciate Firefox send - quite interested to hear how it might be brought back as part of Thunderbird! https://www.youtube.com/watch?v=zt_2xiNjQBo
