这个答案here给出了一种使用powershell将pfx转换为snk的方法（包裹var heartRateSpec = {
service: '180d',
measurement: '2a37'
};
var app = {
initialize: function() {
this.bindEvents();
},
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
},
onDeviceReady: function() {
app.scan();
},
scan: function() {
app.status("Scanning for Heart Rate Monitor");
var foundHeartRateMonitor = false;
function onScan(peripheral) {
// this is demo code, assume there is only one heart rate monitor
console.log("Found " + JSON.stringify(peripheral));
foundHeartRateMonitor = true;
ble.connect(peripheral.id, app.onConnect, app.onDisconnect);
}
function scanFailure(reason) {
alert("BLE Scan Failed");
}
ble.scan([heartRateSpec.service], 5, onScan, scanFailure);
setTimeout(function() {
if (!foundHeartRateMonitor) {
app.status("Did not find a heart rate monitor.");
}
}, 5000);
},
onConnect: function(peripheral) {
app.status("Connected to " + peripheral.id);
ble.startNotification(peripheral.id, heartRateSpec.service, heartRateSpec.measurement, app.onData, app.onError);
},
onDisconnect: function(reason) {
alert("Disconnectedz " + reason);
beatsPerMinute.innerHTML = "...";
app.status("Disconnected");
},
onData: function(buffer) {
var data = new Uint16Array(buffer);
if (heartRate.hasStarted() == false) {
heartRate.beginReading(Date.now());
} else {
var rrIntervals = data.slice(1);
for (i=0; i<rrIntervals.length; i++) {
rrInterval = rrIntervals[i];
heartRate.addReading(rrInterval);
}
}
},
onError: function(reason) {
alert("There was an error " + reason);
},
status: function(message) {
console.log(message);
statusDiv.innerHTML = message;
}
};
app.initialize();
方法）。
如何执行相反的操作，将System.Security.Cryptography文件转换为.snk？我可以使用.pfx阅读.snk文件，并以某种方式使用Get-Content来获取ImportCspBlob对象，但我不知道：
X509Certificate2以获取该证书对象ImportCspBlob 为了它的价值，我尝试实例化.pfx，然后运行X509Certificate2，但构造函数失败了：
ImportCspBlob编辑：
@TheIncorrigible指出了构造函数问题，现在已经修复了。主要问题仍然存在。
我希望空构造函数能够正常工作。
更新：
我不再需要这个问题。事实证明，{em>不是$cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2();
At line:1 char:83
+ ... ect System.Security.Cryptography.X509Certificates.X509Certificate2();

文件中的公私密钥对，而是一些基本的对称密钥材料，密码加密。不过，我会留下这个问题，以防答案对其他人有用。
