# rdup-crypt(1)

encrypt files received from rdup -c

## NAME

rdup-crypt - encrypt files received from **rdup -c**

## SYNOPSIS

**rdup-crypt** *KEYFILE* \[ *OPTION* \]

## DESCRIPTION

**rdup-crypt**, by default,  encrypts the data it receives from **rdup** with the key contained in *KEYFILE*. The default algorithm used is blowfish

For example,

        rdup -c list ~/Documents \| rdup-crypt KEY \| rdup-snap -c -b /tmp/storage

Note the *-c* option for **rdup-snap**. Also note that you cannot change the output FORMAT of **rdup-crypt**. The FORMAT used is rdup's default.

## OPTIONS

- **-c**

  This option is ignored, **rdup-crypt** always works on the files' content. This "feature" was added because all rdup-util scripts have such an option.

- **-d**

  Decrypt the files.

- **-h**

  Show a short help message.

- **-V**

  Show the version.
