Hi all,
I have not seen it yet, so I thought it might be useful for some of you. doa allows you to create deterministic .onion addresses for your Tor Hidden Service. This might be useful if you travel a lot and like to use your Tor Hidden Service for daily communications, without saving your keys on your device, in case border control would search your device.
It uses a password and salt, so that Alice and Bob can share the password with friends and can generate the salt with nora on their own. This procedure allow to change the .onion addresses on a daily base, with out sharing the information in advance, of the current .onion URL.
Hope you like the idea!
