    jCasbin

    jCasbin

    An authorization library that supports access control models

    An authorization library that supports access control models like ACL, RBAC, ABAC for Golang, Java, C/C++, Node.js, Javascript, PHP, Laravel, Python, .NET (C#), Delphi, Rust, Ruby, Swift (Objective-C), Lua (OpenResty), Dart (Flutter) and Elixir. In Casbin, an access control model is abstracted into a CONF file based on the PERM metamodel (Policy, Effect, Request, Matchers). So switching or upgrading the authorization mechanism for a project is just as simple as modifying a configuration. Besides memory and file, Casbin policy can be stored into lots of places. Currently, dozens of databases are supported, from MySQL, Postgres, Oracle to MongoDB, Redis, Cassandra, AWS S3. jCasbin is a powerful and efficient open-source access control library for Java projects. It provides support for enforcing authorization based on various access control models.

    File-Security-SDK

    EaseFilter Comprehensive File Security SDK

    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.

    Format-Preserving Encryption

    Format-Preserving Encryption Library for Java

    This package implements the FF1, FF3, and FFX algorithms and the A2 and A10 parameter sets for format-preserving encryption. The FF1 and FF3 methods for format-preserving encryption are implementations of NIST Special Publication 800-38G, Recommendation for Block Cipher Modes of Operation: Methods for Format-Preserving Encryption. The FFX algorithm and A2 and A10 parameter sets are implementations of "The FFX Mode of Operation for Format-Preserving Encryption," by Mihir Bellare, Phillip Rogaway, and Terence Spies. For more information see the README.txt and package-info.java files in the source.

    Hystrix

    Hystrix

    Latency and Fault Tolerance for Distributed Systems

    Defend your app with Hystrix, a latency and fault tolerance library developed by the Netflix API team. It works by isolating points of access to remote systems, services and 3rd party libraries, thereby stopping cascading failure and providing fallback options, and making complex distributed systems more resilient in cases where failure is inevitable. In a distributed environment, failure is simply inevitable for some service dependencies. With Hystrix you can control the interactions between these distributed services and protect your host application. Hystrix also allows you to fail fast and rapidly recover, fallback and gracefully degrade when possible, and monitor and control operations near real-time.

    OnAccessFileEncryption

    OnAccessFileEncryption

    EaseFilter OnAcess File Encryption SDK

    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 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. The EaseFilter file system filter driver can log, observe, modify, or even prevent the I/O operations for one or more file systems or file system volumes.

    SecureShareExample

    SecureShareExample

    EaseFilter File Secure Sharing Example

    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.
