What is age? It might mean Actually Good Encryption. It's a tool that makes encryption easy, by not having any configuration options.
Use your package manager to install age.
| OS | Command |
|---|---|
| Windows | choco install age.portable |
| Mac | brew install age |
| Ubuntu | apt install age |
Or use the web version (work in progress).
To encrypt to someone's public key:
age --encrypt --recipient age1publickey --output encrypted-file.txt.age input-file.txt
You can provide many recipients by repeating --recipient public-key for each one.
If you want to make your own key, so that you can be a recipient, then you use age-keygen.
age-keygen --output secret-key.txt
Now your secret key is in secret-key.txt (never share it), and the public key (share that one) is printed to the screen, and is also in secret-key.txt, so you don't lose it.
A public key is in lowercase, and a secret key is in caps. Never share the yelling one!
To decrypt a message sent to you:
age --decrypt --identity path/to/secret-key.txt encrypted-file.txt.age
