This library is designed to be a small, flexible and convenient wrapper for a variety of crypto algorithms. So it can be used in a small microcontroller as well as in a high load server application. Also, it provides several custom hybrid algorithms that combine different crypto algorithms to solve common complex cryptographic problems in an easy way. This eliminates the requirement for developers to have strong cryptographic skills.

The library is available for different platforms and contains wrappers for other languages.

The Virgil Security Crypto C library is decomposed into small libraries with specific purposes. A developer can freely choose a subset of libraries.

This library contains basic cryptographic algorithms and can be used as building blocks for complex solutions.

The cryptographic background for the Password-Hardened Encryption (PHE) protocol that provides developers the technology to protect user passwords from offline attacks and render stolen passwords useless even if your database has been compromised. The service implementation can be found here.

The cryptographic background for the Pythia PRF Service.
