C#版开源免费的Bouncy Castle密码库

前言

今天大姚给大家分享一款C#版开源、免费的Bouncy Castle密码库：BouncyCastle。

项目介绍

BouncyCastle是一款C#版开源、免费的Bouncy Castle密码库，开发人员可以通过该项目在他们的 C# 应用程序中使用 Bouncy Castle 提供的各种密码学功能，从而加强数据的安全性和保护隐私信息。

Bouncy Castle密码学库介绍

Bouncy Castle是一个流行的密码学库，提供了广泛的密码算法和协议的实现。它由澳大利亚注册的慈善组织“Bouncy Castle军团”开发，旨在提供可靠而安全的加密解决方案。
