Open Source Java Encryption Software

This is a non-causal non-linear encryption system that cannot be cracked by the von-neuman architectures available today

CryptoServer is the daemon for handling Sign-Verify, Encryption-Dencryption, Envelop-Openenvelop based on OpenSSL including the SEED symmetric algorithm (Korean Standard Symmetric Algorithm). It's interface is just tcp/ip socket and very easy to handle

A cross platform implementation of ECDSA (elliptic curve digital signature algorithm) interface to the aSuretee Token.

The EaseFilter File Control SDK is a powerful development toolkit for creating robust, kernel-level file security and data protection solutions on the Windows platform. It includes a high-performance file system filter driver that intercepts and manages all file I/O operations in real time, giving developers deep, granular control far beyond what is possible with standard Windows APIs or Access Control Lists (ACLs). The EaseFilter Control Filter Driver provides a powerful method for intercepting file I/O operations at both the pre-operation and post-operation stages. This dual-layered interception enables comprehensive monitoring and enforcement of file access policies.

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.

A command-line to help encipher and decipher your password based on a simple algorithm. Java version provides GUI.

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.
