File encrypter
C program (and tiny lib/wrapper) for encrypting/decrypting files using aes256.
The src/encrypt.c file is made so you can use it in other
programs, simply copy src/encrypt.*, src/misc.*, src/lib/ to your project.
Feel free to PR.
Compiling
Simply run:
$ git clone https://github.com/r4v10l1/file-encrypter
$ cd file-encrypter
$ make
...
$ ./file-encrypter.out -h
...Installing
For adding the program to the path and installing the manpage, run:
$ sudo make install
...
$ man file-encrypter # Or file-encrypter -h
...Usage
SYNOPSIS
./file-encrypter.out [-h] [-p password] -e|-d input output
OPTIONS
-h Show this help.
-p password
Use password when encrypting or decrypting the file, instead of
asking for one
-e input output
Encrypts data from input and writes to output. They can be file
names or in the case of '-' it will read/write from stdin and
stdout. Keep in mind that if you don't use -p, it will try to
read the password from stdin as well.
-d input output
Decrypts data from input and writes to output. Just like with
-e, they can be file names or in the case of '-' it will
read/write from stdin and stdout.
EXAMPLES
file-encrypter -e input.txt output.txt
Will encrypt the contents of input.txt and write them to out-
put.txt.
file-encrypter -p "t3st!" -d input.txt output.txt
Will decrypt the contents of input.txt using "t3st!" as password
and write them to output.txt.
cat some-stuff.txt | file-encrypter -p "my-p4ss" -e - output.txt
Will encrypt the contents of stdin (in this case what he got
from the cat(1) pipe) using "my-p4ss" as password and write them
to output.txt.
