File Encrypt/Decrypt

This tool can be handy to quickly encrypt and decrypt files using OpenSSL.

Options

Name	Description	Default
KEY_FILE	The file name for the enc/dec key	secret.pem
KEY_LEN	Length of the key generated	8192
FILE	The file which will be encrypted	none

Creating Keys

Create a key with default values:

make key 

Create a key with a sepecified length and file name:

make key KEY_FILE=custom.pem KEY_LEN=1024

Encrypting Files

Once you've generated the key, you may encrypt a file. The generated filename will be the same as the input file name with .enc appended to it.

make encrypt FILE=secret.txt

Decrypting Files

To decrypt a file, pass in the filename without the .enc extension.

make decrypt FILE=secret.txt
