I'm new in node.js and I need to implement digital signatures.The Scenario is that, a user "A" will send some data by signing it with its private key (Stored on local machine) on to the server. 我是node.js的新手，我需要实现数字签名。这种情况是，用户“ A”将通过使用其私钥（存储在本地计算机上）签名到服务器上来发送一些数据。 So any other user "B" can verify it by decrypting the data with public key (Stored in DB on server) of "A". 因此，任何其他用户“ B”都可以通过使用“ A”的公共密钥（存储在服务器上的DB中）解密数据来验证它。 Now following are my questions. 现在是我的问题。 How to generate public private keys? 如何生成公共私钥？ How to store private key on local machine? 如何在本地计算机上存储私钥？ How to sign data using private key and how to verify it using public key? 如何使用私钥签名数据以及如何使用公钥验证数据？
