# Caesar
_Caesar_ is a desktop app that uses the [age file encryption format](https://github.com/FiloSottile/age) to encrypt/decrypt files.
Download the latest version from the [releases page](https://github.com/fibo/Caesar/releases).
_Caesar_ app __never connects to the Internet__ by design. Automatic updates are not implemented.
It has no dependency other than [typage](https://github.com/FiloSottile/typage)
which is an official TypeScript implementation of _age file encryption format_.
If your OS or architecture is not included in the _releases page_ it is easy to build _Caesar_, basically by running `npm run make`: see instructions in the [CONTRIBUTING.md](./.github/CONTRIBUTING.md) file.
[Gaius Iulius Caesar](https://en.wikipedia.org/wiki/Julius_Caesar) in 58 B.C. used one of the oldest encryption techniques of which we have records: the Caesar cipher.
The _Caesar_ app name should be pronounced as `[ˈkɐ̯ɛ̯.säːr]` with a hard "K" sound at the beginning and the "ae" diphthong pronounced like the English word "eye", as in Classical Latin _restituta_ pronunciation.
## Installation
On Mac you need to download latest _dmg_ file from [releases](https://github.com/fibo/Caesar/releases/), click it and move it to _Applications_. Then open a terminal and launch
```shell
xattr -c /Applications/Caesar.app
```
otherwise you will get a warning like
> App is damaged ... move it to bin
