rage 是一个简单、现代、安全的文件加密工具，使用 age 格式。它的特点是小的显式密钥，没有配置选项，以及UNIX风格的可组合性。
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.
