Usage

Encrypt File

# Encrypt File
## This will generate encrypted file in the same directory of origin file.
## The encrypted file's format is `Lit`.
## So `abc.zip` will be `abc.zip.Lit` after encryption.
litaes e file_to_encrypt password
litaes encrypt file_to_encrypt password
litaes e file_to_encrypt -p [password]
litaes encrypt file_to_encrypt -p [password]
litaes e file_to_encrypt --password [password]
litaes encrypt file_to_encrypt --password [password]
### The command could be `e` or `encrypt`, they are same.
### `-p` is an alias of `--password`, and
### `-p` is optional for providing password.
### But if you want input your password, keep `-p` empty.

Decrypt File

[!CAUTION] This tool can only decrypt files encrypted by this tool.

# Decrypt File
## This will generate decrypted file in the same directory of origin file.
## The decrypted file's format is `Til`.
## For example, `abc.zip.Lit` will be decrypted to `abc.zip.Til`.
## Why not just `abc.zip`? Because you may perform decryption in the same directory.
litaes d file_to_decrypt password
litaes decrypt file_to_decrypt password
litaes d file_to_decrypt -p [password]
litaes decrypt file_to_decrypt -p [password]
litaes d file_to_decrypt --password [password]
litaes decrypt file_to_decrypt --password [password]
### Just like in `Encrypt File`,
### The command could be `e` or `encrypt`, they are same.
### `-p` is an alias of `--password`, and
### `-p` is optional for providing password.
### But if you want input your password, keep `-p` empty.

Additional

About Password

If you want to supply your password from environment variables.

There is a way to do that. LITAES_PASSWORD, keep it uppercase.

# example in powershell
$env:LITAES_PASSWORD='password'

And the priority is

command plain password > -p, --password > LITAES_PASSWORD
