    A Node.js implementation toolkit, aim to secure the communication channel based on Hash(sha256), Digital Signature(ecdsa with curve secp256r1 or prime256v1) and Encryption(aes with CTR mode).

    install

    npm i secure_channel
    

    create signed data, and verify

    var sc = require('secure_channel')
    
    var senderKeyPair = sc.generateECKeyPair()
    
    var data = "hello world"
    
    var signedData = sc.calSignedData(senderKeyPair.PrivateKey, data)
    
    // if signedData has been changed or no from the right sender, the following verification will fail
    
    var result = sc.verifySignedData(senderKeyPair.PublicKey, signedData)
    

    create signed encrypted data, and verify

    var sc = require('secure_channel')
    
    var senderKeyPair = sc.generateECKeyPair()
    var receiverKeyPair = sc.generateECKeyPair()
    
    var data = "hello world"
    
    var encSignedData = sc.calEncSignedData(senderKeyPair.PrivateKey, receiverKeyPair.PublicKey, data)
    
    // the encSignedData is encrypted, can not learn anything about the data
    // and if encSignedData has been changed or no from the right sender, the following verification will fail
    
    var result = sc.verifyEncSignedData(receiverKeyPair.PrivateKey, senderKeyPair.PublicKey, encSignedData)
