Timelock encryption
Encrypt Hello dee! string to 30 seconds in the future, using quicknet publickey. If you wait 30 seconds before decrypting, the message is decrypted using the new quicknet signature.
echo 'Hello dee!' | dee crypt -u quicknet -r 30s > data.dee
dee crypt --decrypt data.dee
Hello dee!

dee does not come with a default remote beacon. You should decide whichever suit your needs.
More beacons origin are available on drand website.
Security Considerations
This software has not been audited. Please use at your sole discretion. With this in mind, dee security relies on the following:
- tlock: Practical Timelock Encryption from Threshold BLS by Nicolas Gailly, Kelsey Melissaris, and Yolan Romailler, and its implementation in thibmeu/tlock-rs,
- Identity-Based Encryption by Dan Boneh, and Matthew Franklin, and its implementation in thibmeu/tlock-rs,
- The League of Entropy to remain honest,
- age encryption protocol, and its implementation in str4d/rage,
FAQ
Default configuration path
dee configuration file is available at the following
| OS | Path |
|---|---|
| Linux | /home/alice/.config/dee/default.toml |
| Windows | C:\Users\Alice\AppData\Roaming\dee\config\default.toml |
| macOS | /Users/Alice/Library/Application Support/rs.dee/default.toml |
Other implementations
drand API specification is at drand.love/docs/specification. drand is based on Scalable Bias-Resistant Distributed Randomness by Ewa Syta, Philipp Jovanovic, Eleftherios Kokoris Kogias, Nicolas Gailly, Linus Gasser, Ismail Khoffi, Michael J. Fischer, and Bryan Ford. The reference interroperable Go implementation is available at drand/drand.
timelock encryption was published in tlock: Practical Timelock Encryption from Threshold BLS by Nicolas Gailly, Kelsey Melissaris, and Yolan Romailler. The reference interroperable Go implementation is available at drand/tlock.
Rust libraries
dee focuses on building a cli. It relies on Rust libraries to use drand or perform timelock encryption.
If you're looking to implement your own Rust application on top of drand and/or timelock encryption, you can use the following:
- drand_core: drand client,
- tlock: raw tlock implementation, allowing messages up to 16 bytes,
- tlock_age: hybrid encryption, age phassphrase is encrypted using tlock,
