Windows Forms application that provides symmetric and asymmetric encryption. Besides encryption, it provides text decryption depending on the encryption algorithm (AES or RSA). For the sake of creating digital signatures, text hash value is calculated with SHA-256 hashing algorithm, and encrypted with RSA asymmetric algorithm. The last option pr…

Hedged signatures for (some) protection against fault attacks.

This project aims to create a secure communication system between the university entity and its students and professors. The system operates on a client-server architecture, prioritizing information security through various encryption technologies.

Toy Digital Signatures implemented using Public Key Crypto for signing and verification, SHA1 for hashing.

The Web 7.0 Portable Trust Library (PTL) is used to support all of the trust operations required to develop Web 7.0 Trusted Personal Agents (and supporting components) across multiple operating system environments. The PTL supports the Web 7.0 goal of "making decentralized systems easy-to-understand and easier for you to implement".
