Open Source Python File Systems

FSFS is a secure distributed file system in user space built over FUSE and OpenSSL. It stores AND transfers data between clients and server in secure form, leaving most of the cryptography to the clients, thus relieving the server of the additional work.

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.

PyGFS is a reliable and secure distributed file system that runs completely in userspace. It supports x509 certificate authentication, authorization and encryption mechanisms to provide secure access over insecure networks.

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.

EaseFilter File System Filter Driver Framework is a set of file system filter driver software development kit which includes file monitor filter driver, file access control filter driver, transparent file encryption filter driver, process filter driver and registry filter driver. The File Security Solution with the EaseFilter Comprehensive File Security SDK encompasses file security, digital rights management, encryption, file monitoring, file auditing, file tracking, data loss prevention, process monitoring and protection, and system configuration protection. EaseFilter file system filter driver is a kernel-mode component that runs as part of the Windows executive above the file system. The EaseFilter file system filter driver can intercept requests targeted at a file system or another file system filter driver. By intercepting the request before it reaches its intended target, the filter driver can extend or replace functionality provided by the original target of the request.
