matrioska 0.0.1

Command line tool and Python library for data encryption

matrioska

Command line tool and Python library for data symmetric encryption

Features

• Generate a random (base64 encoded) 32 bytes passphrase (for AES256)
• Key provided via environment variable name (to avoid command line exposure)
• Encrypts from stdin or filename into stdout/filename
• Decrypts from stdin or filename into stdout/filename

The encryption is performed using AES-256 in EAX mode via the PyCryptodome library.

Install

pip install matrioska

Usage

# Generate a random encryption key and story in an environment variable
export KEY=$(matrioska --gen-key)

# Encrypt stdin
echo "This is a very secret sentence" | matrioska -k KEY > /tmp/secret

# Decrypt stdin
cat /tmp/secret | matrioska -k KEY -d

# Encrypt file omitting both source and destioname filenames from command line
matrioska -k KEY < /etc/passwd > /tmp/secret_file

# Decrypt file omitting both source and destioname filenames from command line
matrioska -k KEY -d < /tmp/secret_file > /tmp/secret
