+
+age is a simple, modern and secure file encryption tool, format, and Go library.
+
+It features small explicit keys, no config options, and UNIX-style composability.
+
+```
+$ age-keygen -o key.txt
+Public key: age1ql3z7hjy54pw3hyww5ayyfg7zqgvc7w3j2elw8zmrj2kg5sfn9aqmcac8p
+$ tar cvz ~/data | age -r age1ql3z7hjy54pw3hyww5ayyfg7zqgvc7w3j2elw8zmrj2kg5sfn9aqmcac8p > data.tar.gz.age
+$ age --decrypt -i key.txt data.tar.gz.age > data.tar.gz
+```
+
+📜 The format specification is at [age-encryption.org/v1](https://age-encryption.org/v1). age was designed by [@Benjojo12](https://twitter.com/Benjojo12) and [@FiloSottile](https://twitter.com/FiloSottile).

+
+🦀 An alternative interoperable Rust implementation is available at [github.com/str4d/rage](https://github.com/str4d/rage).
+
+🔑 Hardware PIV tokens such as YubiKeys are supported through the [age-plugin-yubikey](https://github.com/str4d/age-plugin-yubikey) plugin.
+
+💬 The author pronounces it `[aɡe̞]`, like the Italian [“aghe”](https://translate.google.com/?sl=it&text=aghe).

+
+## Usage
+
+For the full documentation, read [the age(1) man page](https://filippo.io/age/age.1).
+
+```
+Usage:
+    age [--encrypt] (-r RECIPIENT | -R PATH)... [--armor] [-o OUTPUT] [INPUT]
+    age [--encrypt] --passphrase [--armor] [-o OUTPUT] [INPUT]
+    age --decrypt [-i PATH]... [-o OUTPUT] [INPUT]
+
+Options:
+    -e, --encrypt               Encrypt the input to the output. Default if omitted.
+    -d, --decrypt               Decrypt the input to the output.
+    -o, --output OUTPUT         Write the result to the file at path OUTPUT.
+    -a, --armor                 Encrypt to a PEM encoded format.
+    -p, --passphrase            Encrypt with a passphrase.
+    -r, --recipient RECIPIENT   Encrypt to the specified RECIPIENT. Can be repeated.
+    -R, --recipients-file PATH  Encrypt to recipients listed at PATH. Can be repeated.
+    -i, --identity PATH         Use the identity file at PATH. Can be repeated.
+
+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 generated by age-keygen ("age1...")
+or an SSH public key ("ssh-ed25519 AAAA...", "ssh-rsa AAAA...").
+
+Recipient files contain one or more recipients, one per line. Empty lines
+and lines starting with "#" are ignored as comments. "-" may be used to
+read recipients from standard input.
+
+Identity files contain one or more secret keys ("AGE-SECRET-KEY-1..."),
+one per line, or an SSH key. Empty lines and lines starting with "#" are
+ignored as comments. Passphrase encrypted age files can be used as
+identity files. Multiple key files can be provided, and any unused ones
+will be ignored. "-" may be used to read identities from standard input.
+
+When --encrypt is specified explicitly, -i can also be used to encrypt to an
+identity file symmetrically, instead or in addition to normal recipients.
+```
+
+### Multiple recipients
+
+Files can be encrypted to multiple recipients by repeating `-r/--recipient`. Every recipient will be able to decrypt the file.
+
+```
+$ age -o example.jpg.age -r age1ql3z7hjy54pw3hyww5ayyfg7zqgvc7w3j2elw8zmrj2kg5sfn9aqmcac8p \
+    -r age1lggyhqrw2nlhcxprm67z43rta597azn8gknawjehu9d9dl0jq3yqqvfafg example.jpg
+```
+
+#### Recipient files
+
+Multiple recipients can also be listed one per line in one or more files passed with the `-R/--recipients-file` flag.
+
+```

+$ age -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 age will automatically generate a secure passphrase. Passphrase protected files are automatically detected at decrypt time.
+
+```
+$ age -p secrets.txt > secrets.txt.age
+Enter passphrase (leave empty to autogenerate a secure one):
+Using the autogenerated passphrase "release-response-step-brand-wrap-ankle-pair-unusual-sword-train".
+$ age -d secrets.txt.age > secrets.txt
+Enter passphrase:
+```
+
+### Passphrase-protected key files
+
+If an identity file passed to `-i` is a passphrase encrypted age file, it will be automatically decrypted.
+
+```
+$ age-keygen | age -p > key.age
+Public key: age1yhm4gctwfmrpz87tdslm550wrx6m79y9f2hdzt0lndjnehwj0ukqrjpyx5
+Enter passphrase (leave empty to autogenerate a secure one):
+Using the autogenerated passphrase "hip-roast-boring-snake-mention-east-wasp-honey-input-actress".
+$ age -r age1yhm4gctwfmrpz87tdslm550wrx6m79y9f2hdzt0lndjnehwj0ukqrjpyx5 secrets.txt > secrets.txt.age
+$ age -d -i key.age secrets.txt.age > secrets.txt
+Enter passphrase for identity file "key.age":
+```
+
+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, age 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.)
+
+```
+$ age -R ~/.ssh/id_ed25519.pub example.jpg > example.jpg.age
+$ age -d -i ~/.ssh/id_ed25519 example.jpg.age > example.jpg
+```
+
+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.
+
+#### Encrypting to a GitHub user
+
+Combining SSH key support and `-R`, you can easily encrypt a file to the SSH keys listed on a GitHub profile.
+
+```
+$ curl https://github.com/benjojo.keys | age -R - example.jpg > example.jpg.age
+```
+
+Keep in mind that people might not protect SSH keys long-term, since they are revokable when used only for authentication, and that SSH keys held on YubiKeys can't be used to decrypt files.

+// Package age implements file encryption according to the age-encryption.org/v1
+// specification.
+//
+// For most use cases, use the Encrypt and Decrypt functions with
+// X25519Recipient and X25519Identity. If passphrase encryption is required, use
+// ScryptRecipient and ScryptIdentity. For compatibility with existing SSH keys
+// use the filippo.io/age/agessh package.
+//
+// age encrypted files are binary and not malleable. For encoding them as text,
+// use the filippo.io/age/armor package.
+//
+// Key management
+//
+// age does not have a global keyring. Instead, since age keys are small,
+// textual, and cheap, you are encouraged to generate dedicated keys for each
+// task and application.
+//
+// Recipient public keys can be passed around as command line flags and in
+// config files, while secret keys should be stored in dedicated files, through
+// secret management systems, or as environment variables.
+//
+// There is no default path for age keys. Instead, they should be stored at
+// application-specific paths. The CLI supports files where private keys are
+// listed one per line, ignoring empty lines and lines starting with "#". These
+// files can be parsed with ParseIdentities.
+//
+// When integrating age into a new system, it's recommended that you only
+// support X25519 keys, and not SSH keys. The latter are supported for manual
+// encryption operations. If you need to tie into existing key management
+// infrastructure, you might want to consider implementing your own Recipient
+// and Identity.
+//
+// Backwards compatibility
+//
+// Files encrypted with a stable version (not alpha, beta, or release candidate)
+// of age, or with any v1.0.0 beta or release candidate, will decrypt with any
+// later versions of the v1 API. This might change in v2, in which case v1 will
+// be maintained with security fixes for compatibility with older files.
+//
+// If decrypting an older file poses a security risk, doing so might require an
+// explicit opt-in in the API.

-Package secretbox encrypts and authenticates small messages.
-
-Secretbox uses XSalsa20 and Poly1305 to encrypt and authenticate messages with
-secret-key cryptography. The length of messages is not hidden.
-
-It is the caller's responsibility to ensure the uniqueness of nonces—for
-example, by using nonce 1 for the first message, nonce 2 for the second
-message, etc. Nonces are long enough that randomly generated nonces have
-negligible risk of collision.
-
-Messages should be small because:
-
-1. The whole message needs to be held in memory to be processed.
-
-2. Using large messages pressures implementations on small machines to decrypt
-and process plaintext before authenticating it. This is very dangerous, and
-this API does not allow it, but a protocol that uses excessive message sizes
-might present some implementations with no other choice.
-
-3. Fixed overheads will be sufficiently amortised by messages as small as 8KB.
-
-4. Performance may be improved by working with messages that fit into data caches.
-
-Thus large amounts of data should be chunked so that each message is small.
-(Each message still needs a unique nonce.) If in doubt, 16KB is a reasonable
-chunk size.
