Simple symmetric GPG file encryption and decryption.

Project description


Simple symmetric GPG file encryption and decryption


Crypro provides a simple interface to symmetric Gnu Privacy Guard (gpg) encryption and decryption for one or more files on Unix and Linux platforms. It runs on top of gpg and requires a gpg install on your system. Encryption is performed with the AES256 cipher algorithm.

Encryption benchmarks vs. default gpg encryption are available here with additional details for text, pdf, mp3, and png mime types.

Crypro provides a number of options including automated tar archives of multiple files prior to encryption, portable ASCII armored encryption formatting, and SHA256 hash digest generation for your encrypted files.


Detailed documentation is available here.


Encrypt a File

$ Crypro sometext.txt

Encrypt with Portable ASCII Armored Format

$ Crypro --armor sometext.txt

Encrypt Multiple Files with Same Passphrase

$ Crypro sometext.txt anotherimage.jpg

Encrypt Multiple Files with Wildcard Expansion

$ Crypro *.txt

Encrypt and Generate SHA256 Hash Digest of the Encrypted File

$ Crypro --hash sometext.txt

Encrypt All Top Level Files in Multiple Directories with Same Passphrase

$ Crypro imagedir privatedir

Pack Multiple Files in a Tar Archive, Then Encrypt the Archive

$ Crypro --tar privatedir

Decrypt a File

$ deCrypro sometext.txt.crypt

Decrypt All Encrypted Files in Top Level of Directory

$ deCrypro privatedir

Decrypt Text to Standard Output Stream

$ deCrypro --stdout sometext.txt.gpg


1) Install GPG

Mac OSX Users

Mac OSX users can install gpg from source, with Homebrew, or by installing the Mac GPG Tools Suite.

The Homebrew install command is:

brew install gpg

Please refer to the detailed documentation on the Gnu Privacy Guard and Mac GPG Tools suite sites for more information if you choose the source or GPG Tools approaches.

Linux Users

If gpg is not installed on your Linux distro, you can use your package manager to install it or compile and install it from the source.

2) Install Crypro

You can install Crypro with pip:

pip install Crypro

or download the Crypro source, unpack it, navigate to the top level directory, and install with the command:

python install


Crypro Options

--armor | -a

Encrypt in a portable ASCII armored format


Generate SHA256 hash digest of encrypted file(s)


Favor reduced file size over encryption speed


Favor encryption speed over reduced file size


Create tar archives from directories of files, then encrypt

deCrypro Options


Do not automatically unpack tar archives after decryption

--overwrite | -o

Overwrite an existing file with the new decrypted file

--stdout | -s

Push the decrypted data to the standard output stream instead of generating a new file
