软件介绍
Forge 是一个 TLS 协议的本地实现，一个实用的加密程序以及一组利用多网络资源开发 Web 应用的工具。
Transports
TLS：提供本地 JavaScript 客户端和服务器端 TLS 实现。
例如：
// create TLS client
var client = forge.tls.createConnection({
server: false,
caStore: /* Array of PEM-formatted certs or a CA store object */,
sessionCache: {},
// supported cipher suites in order of preference
cipherSuites: [
forge.tls.CipherSuites.TLS_RSA_WITH_AES_128_CBC_SHA,
forge.tls.CipherSuites.TLS_RSA_WITH_AES_256_CBC_SHA],
virtualHost: 'example.com',
verify: function(connection, verified, depth, certs) {
if(depth === 0) {
var cn = certs[0].subject.getField('CN').value;
if(cn !== 'example.com') {
verified = {
alert: forge.tls.Alert.Description.bad_certificate,
message: 'Certificate common name does not match hostname.'
};
}
}
return verified;
},
connected: function(connection) {
console.log('connected');
// send message to server
connection.prepare(forge.util.encodeUtf8('Hi server!'));
/* NOTE: experimental, start heartbeat retransmission timer
myHeartbeatTimer = setInterval(function() {
connection.prepareHeartbeatRequest(forge.util.createBuffer('1234'));
}, 5*60*1000);*/
},
/* provide a client-side cert if you want
getCertificate: function(connection, hint) {
return myClientCertificate;
},
/* the private key for the client-side cert if provided */
getPrivateKey: function(connection, cert) {
return myClientPrivateKey;
},
tlsDataReady: function(connection) {
// TLS data (encrypted) is ready to be sent to the server
sendToServerSomehow(connection.tlsData.getBytes());
// if you were communicating with the server below, you'd do:
// server.process(connection.tlsData.getBytes());
},
dataReady: function(connection) {
// clear data from the server is ready
console.log('the server sent: ' +
forge.util.decodeUtf8(connection.data.getBytes()));
