我有一个Node.js应用,需要检查外部资源的TLS兼容性。我需要限制Node.js在发出外部TLS请求时将使用的特定密码。我正在寻找实现此目的的示例代码。
更多信息:Apple要求iOS 9 all outbound connections be encrypted,并且允许的密码列表有限。
接受的密码是:
TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
我的目标是构建一项服务,检查以确保外部服务器符合Apple的要求。

您可以使用该密码列表连接到每个资源。如果连接成功,那么您知道其中一个密码正在使用,因此检出。可以通过ciphers
属性设置独有的密码列表。例如:
var ciphers = ['TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384',
'TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256',
'TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384',
'TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA',
'TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256',
'TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA',
'TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384',
'TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256',
'TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384',
'TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256',
'TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA'].join(':');
tls.connect({
host: 'example.com',
port: 443,
ciphers: ciphers
}, function() {
// Success!
}).on('error', function(err) {
// Unsuccessful! You may check `err` to make sure it wasn't an unexpected
// error like ECONNREFUSED
});
您还可以通过设置secureProtocol
属性来限制使用的协议。例如,要使用TLSv1.2:
var ciphers = ['TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384',
'TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256',
'TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384',
'TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA',
'TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256',
'TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA',
'TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384',
'TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256',
'TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384',
'TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256',
'TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA'].join(':');
tls.connect({
host: 'example.com',
port: 443,
ciphers: ciphers,
secureProtocol: 'TLSv1_2_method'
}, function() {
// Success!
}).on('error', function(err) {
// Unsuccessful! You may check `err` to make sure it wasn't an unexpected
// error like ECONNREFUSED
});
