rage 是一個(gè)簡(jiǎn)單、現(xiàn)代、安全的文件加密工具，使用 age 格式。它的特點(diǎn)是小的顯式密鑰，沒(méi)有配置選項(xiàng)，以及UNIX風(fēng)格的可組合性。

Usage:
  rage [--encrypt] -r RECIPIENT [-i IDENTITY] [-a] [-o OUTPUT] [INPUT]
  rage --decrypt [-i IDENTITY] [-o OUTPUT] [INPUT]

Positional arguments:
  INPUT                       Path to a file to read from.

Optional arguments:
  -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 WF        Maximum work factor to allow for passphrase decryption.
  -a, --armor                 Encrypt to a PEM encoded format.
  -r, --recipient RECIPIENT   Encrypt to the specified RECIPIENT. May be repeated.
  -R, --recipients-file PATH  Encrypt to the recipients listed at PATH. May be repeated.
  -i, --identity IDENTITY     Use the identity file at IDENTITY. May be repeated.
  -o, --output OUTPUT         Write the result to the file at path OUTPUT.

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

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).

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