# rage: Rust implementation of age



rage is a simple, modern, and secure file encryption tool, using the *age*

format. It features small explicit keys, no config options, and UNIX-style

composability.



The format specification is at [age-encryption.org/v1](https://age-encryption.org/v1).

age was designed by [@Benjojo](https://benjojo.co.uk/) and

[@FiloSottile](https://bsky.app/profile/did:plc:x2nsupeeo52oznrmplwapppl).



The reference interoperable Go implementation is available at

[filippo.io/age](https://filippo.io/age).



Hardware PIV tokens such as YubiKeys are supported through the

[age-plugin-yubikey](https://github.com/str4d/age-plugin-yubikey) plugin.



For more plugins, implementations, tools, and integrations, check out the

[awesome age](https://github.com/FiloSottile/awesome-age) list.

On Windows, Linux, and macOS, you can use the

[pre-built binaries](https://github.com/str4d/rage/releases).



> Help from new packagers is very welcome. Please use the package name `rage`;

> the fallback package name `rage-encryption` should be used only when there are

> *unavoidable* name conflicts in package systems that use global namespaces. Do

> not rename any binaries; instead use your package system's conflicting package

> mechanism to prevent installation of both packages at once.



## Usage



```

Usage: rage [--encrypt] (-r RECIPIENT | -R PATH)... [-i IDENTITY] [-a] [-o OUTPUT] [INPUT]

       rage [--encrypt] --passphrase [-a] [-o OUTPUT] [INPUT]

       rage --decrypt [-i IDENTITY] [-o OUTPUT] [INPUT]



Arguments:

  [INPUT]  Path to a file to read from.



Options:

  -h, --help                    Print this help message and exit.

  -V, --version                 Print version info and exit.

  -e, --encrypt                 Encrypt the input (the default).

  -d, --decrypt                 Decrypt the input.

  -p, --passphrase              Encrypt with a passphrase instead of recipients.

      --max-work-factor     Maximum work factor to allow for passphrase decryption.

  -a, --armor                   Encrypt to a PEM encoded format.

  -r, --recipient    Encrypt to the specified RECIPIENT. May be repeated.

  -R, --recipients-file   Encrypt to the recipients listed at PATH. May be repeated.

  -i, --identity      Use the identity file at IDENTITY. May be repeated.

  -j               Use age-plugin-PLUGIN-NAME in its default mode as an identity.

  -o, --output          Write the result to the file at path OUTPUT.



INPUT defaults to standard input, and OUTPUT defaults to standard output.

If OUTPUT exists, it will be overwritten.



RECIPIENT can be:

- An age public key, as generated by rage-keygen ("age1...").

- An SSH public key ("ssh-ed25519 AAAA...", "ssh-rsa AAAA...").



PATH is a path to a file containing age recipients, one per line

(ignoring "#" prefixed comments and empty lines). "-" may be used to

read recipients from standard input.



IDENTITY is a path to a file with age identities, one per line

(ignoring "#" prefixed comments and empty lines), or to an SSH key file.

Passphrase-encrypted age identity files can be used as identity files.

Multiple identities may be provided, and any unused ones will be ignored.

"-" may be used to read identities from standard input.

```



### Multiple recipients



Files can be encrypted to multiple recipients by repeating `-r/--recipient`.

Every recipient will be able to decrypt the file.



```bash

$ rage -o example.png.age -r age1uvscypafkkxt6u2gkguxet62cenfmnpc0smzzlyun0lzszfatawq4kvf2u \

    -r age1ex4ty8ppg02555at009uwu5vlk5686k3f23e7mac9z093uvzfp8sxr5jum example.png

```



#### Recipient files



Multiple recipients can also be listed one per line in one or more files passed

with the `-R/--recipients-file` flag.



```

$ cat recipients.txt

# Alice

age1ql3z7hjy54pw3hyww5ayyfg7zqgvc7w3j2elw8zmrj2kg5sfn9aqmcac8p

# Bob

age1lggyhqrw2nlhcxprm67z43rta597azn8gknawjehu9d9dl0jq3yqqvfafg

$ rage -R recipients.txt example.jpg > example.jpg.age

```



If the argument to `-R` (or `-i`) is `-`, the file is read from standard input.



### Passphrases



Files can be encrypted with a passphrase by using `-p/--passphrase`. By default

rage will automatically generate a secure passphrase.



```bash

$ rage -p -o example.png.age example.png

Type passphrase (leave empty to autogenerate a secure one): [hidden]

Using an autogenerated passphrase:

    kiwi-general-undo-bubble-dwarf-dizzy-fame-side-sunset-sibling

$ rage -d example.png.age >example.png

Type passphrase: [hidden]

```



If a binary named `pinentry` is available in `$PATH`, it will be used to ask the

user for a passphrase. The `PINENTRY_PROGRAM` environment variable can be used

to set the binary name or path to use. If a `pinentry` binary is not available,

or `PINENTRY_PROGRAM` is set to the empty string, `rage` will fall back to the

CLI instead.



### Passphrase-protected identity files



If an identity file passed to `-i/--identity` is a passphrase-encrypted age

file, it will be automatically decrypted.



```

$ rage -p -o key.age <(rage-keygen)

Public key: age1pymw5hyr39qyuc950tget63aq8vfd52dclj8x7xhm08g6ad86dkserumnz

Type passphrase (leave empty to autogenerate a secure one): [hidden]

Using an autogenerated passphrase:

    flash-bean-celery-network-curious-flower-salt-amateur-fence-giant

$ rage -r age1pymw5hyr39qyuc950tget63aq8vfd52dclj8x7xhm08g6ad86dkserumnz secrets.txt > secrets.txt.age

$ rage -d -i key.age secrets.txt.age > secrets.txt

Type passphrase: [hidden]

```



Passphrase-protected identity files are not necessary for most use cases, where

access to the encrypted identity file implies access to the whole system.

However, they can be useful if the identity file is stored remotely.



### SSH keys



As a convenience feature, rage also supports encrypting to `ssh-rsa` and

`ssh-ed25519` SSH public keys, and decrypting with the respective private key

file. (`ssh-agent` is not supported.)



```

$ rage -R ~/.ssh/id_ed25519.pub example.png > example.png.age

$ rage -d -i ~/.ssh/id_ed25519 example.png.age > example.png

```



Note that SSH key support employs more complex cryptography, and embeds a public

key tag in the encrypted file, making it possible to track files that are

encrypted to a specific public key.



### Feature flags



When building with Cargo, you can configure rage using `--no-default-features`

and `--features comma,separated,flags` to enable or disable the following

feature flags:



- `mount` enables the `rage-mount` tool, which can mount age-encrypted TAR or

  ZIP archives as read-only. It is currently only usable on Unix systems, as it

  relies on `libfuse`.



- `ssh` (enabled by default) enables support for reusing existing SSH key files

  for age encryption.



- `unstable` enables in-development functionality. Anything behind this feature

  flag has no stability or interoperability guarantees.



## Rust Library



Applications wishing to use rage as a library should use the [`age`](https://crates.io/crates/age)

crate, which rage is built on top of.
