Open Source Python Encryption Software

'Portfolio Secure' is an desktop application developed using python 3.6.8 and other add-on libaries. Can secure files or folders by encrypting into a unreadable file (.enc) . Portfilio secure has two parts: 1) Folder Guardian - converts folders into unreadable file (.enc) 2) File Guardian - converts files into unreable file (.enc) Compatible only for windows OS.

A hook script usable with TortoiseSVN (and possible other subversion clients/GUIs) providing transparent repository encryption (encryption/decryption at the client side).

The EaseFilter Filter Driver SDK is a collection of tools, libraries, and sample code designed to facilitate the creation of Windows file system filter drivers. These drivers operate at a low level, intercepting file I/O requests before they reach the underlying file system or other filter drivers. The EaseFilter SDK provides a powerful interface for developing Windows filter drivers in C++, C#, or other programming languages that support native DLL calls. This guide helps developers understand how to use the SDK effectively to monitor, filter, or control file system activities in real time.

Transparent file encryption performs real-time I/O encryption and decryption of the files in any block data with 16 bytes. The encryption uses a 256 bits symmetric key to encrypt or decrypt the data with AES encryption algorithm. Auto file encryption protects data "at rest", meaning the transparent data and files encryption. It provides the ability to comply with policies which can be applied by users, processes and file type. This allows only authorized users and processes to access the encrypted files, unauthorized users and processes can’t access the encrypted files. The Auto FileCrypt Tool was developed with EaseFilter Encryption Filter Driver(EEFD) SDK, a file level encryption filter driver. Run the auto file encryption service with administrator permission, add the managed folders as encryption folder, when the files were added to the managed folder, the files will be encrypted automatically, when files were read, the data will be decrypted in memory automatically.

EaseFilter DRM Secure File Sharing example was implemented with the Transparent File Encryption and Control Filter Driver SDK. The shared file was encrypted with a unique 256-bits key, store the file access policies in a central server, share the encrypted files with fully control. You can grant, revoke or expire the file access at any time, even after the file has been shared. Digital Rights Management (DRM) enforces how files can be viewed, copied, printed, shared, or modified. Instead of granting blanket access, DRM attaches enforceable usage policies to content. With EaseFilter DRM, you can: Restrict access to authorized users, devices, and applications only. Block forwarding, uploading to unauthorized cloud services, or syncing to personal drives. Apply time-based access (expiration dates) and geo/device restrictions. Maintain tamper-evident audit trails for compliance and forensics.

This command line tool can be used to encrypt and decrypt files and directories using the AWS Encryption SDK. If you have not already installed cryptography, you might need to install additional prerequisites as detailed in the cryptography installation guide for your operating system. Installation using a python virtual environment is recommended to avoid conflicts between system packages and user-installed packages. For the most part, the behavior of aws-encryption-cli in handling files is based on that of GNU CLIs such as cp. A qualifier to this is that when encrypting a file, if a directory is provided as the destination, rather than creating the source filename in the destination directory, a suffix is appended to the destination filename. By default the suffix is .encrypted when encrypting and .decrypted when decrypting, but a custom suffix can be provided by the caller if desired.

The name leet stands for "Linux exquisite encryption tool", it will be a software application for on-the-fly encryption, similar in its functionality to TrueCrypt. The goal of leet however is to be simpler and as user friendly as possible, making encryption and securing of information accessible to anybody, even those who don't necessarily have any prior knowledge of data securing, algorithms and encryption. However it's not targeted at this group of users only, part of the ambition of this project is to reach companies, institutions, governments (etc...) as well.
