Simple symmetric GPG file encryption and decryption.
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.
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
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.
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 setup.py install
--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
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
--help | -h
