这是一个双因素身份验证库和开源多因素身份验证实现。它提供了一套工具,用于实现需要超出标准凭据的第二层验证的安全工作流。 该项目实现了基于时间的一次性密码(TOTP)和基于 HMAC 的一次性密码(HOTP)。它包括用于根据共享密钥和计数器生成这些代码的实用程序,遵循 RFC 6238 等行业标准。 该库涵盖了加密原语,包括 Base32 密钥编码、动态截断提取和对称密钥存储。这些功能使得能够为两步验证系统创建和验证密码。
Provides a tool for creating HMAC-based one-time passwords for secure user verification.
