【问题描述】：
我正在尝试在 OS X 和 iOS（8.1 版本）上使用openssl 之间的 SSL TCP 连接。 Exception Domains 有 192.168.0.104。
Swift iOS 代码：
class SSLSocketLite {
// The input stream.
private var inStream: NSInputStream?
// The output stream.
private var outStream: NSOutputStream?
// The host to connect to.
private var host: String
// The port to connect on.
private var port: Int
init(inHost:String, inPort:Int) {
host = inHost
port = inPort
NSStream.getStreamsToHostWithName(host, port: port, inputStream: &inStream, outputStream: &outStream)
}
func Open() {
inStream?.open()
outStream?.open()
inStream?.setProperty(NSStreamSocketSecurityLevelTLSv1, forKey: NSStreamSocketSecurityLevelKey)
outStream?.setProperty(NSStreamSocketSecurityLevelTLSv1, forKey: NSStreamSocketSecurityLevelKey)
inStream?.scheduleInRunLoop(.mainRunLoop(), forMode: NSDefaultRunLoopMode)
outStream?.scheduleInRunLoop(.mainRunLoop(), forMode: NSDefaultRunLoopMode)
}
func Read() -> String! {
var buffer = Array<UInt8>(count:1024, repeatedValue: 0)
if inStream!.hasBytesAvailable {
inStream!.read(&buffer, maxLength: 1024)
let responseString = NSString(bytes: buffer, length: buffer.count, encoding: NSUTF8StringEncoding) as! String
return responseString
}
return nil
}
func Write(msg:String) {
let data:NSData = msg.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!
outStream!.write(UnsafePointer(data.bytes), maxLength: data.length)
}
func Close() {
inStream?.close()
outStream?.close()
}
}
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let sslsock = SSLSocketLite(inHost: "192.168.0.104", inPort: 1678)
sslsock.Open()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
在 OS X 端，我使用以下方法创建了证书和密钥：
openssl req -x509 -newkey rsa:1024 -keyout key.key -out key.crt -days 365 -nodes
并使用以下方式启动 TCP SSL 服务器：
openssl s_server -key key.key -cert key.crt -accept 1678
在那之后，我在 iOS 端得到了CFNetwork SSLHandshake failed (-9807)，在 OS X 端得到了bad gethostbyaddr。我该如何解决这个问题？
UPD：
1.touch openssl-ca.cnf
2.复制粘贴到openssl-ca.cnf中。改变了一行：
commonName_default = localhost
3.openssl req -x509 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM
4.touch openssl-server.cnf
5.复制粘贴到openssl-server.cnf中。两行更改：
commonName_default = localhost
DNS.1 = localhost
6.openssl req -config openssl-server.cnf -newkey rsa:2048 -sha256 -nodes -out servercert.csr -outform PEM
7.openssl-ca.cnf新增2+1部分：
[ CA_default ]
...
base_dir = .
certificate = $base_dir/cacert.pem # The CA certifcate
private_key = $base_dir/cakey.pem # The CA private key
new_certs_dir = $base_dir # Location for new certs after signing
database = $base_dir/index.txt # Database index file
serial = $base_dir/serial.txt # The current serial number
unique_subject = no # Set to 'no' to allow creation of
# several certificates with same subject.

8.touch index.txt
9.echo '01' > serial.txt
10.openssl ca -config openssl-ca.cnf -policy signing_policy -extensions signing_req -out servercert.pem -infiles servercert.csr
11.openssl x509 -in servercert.pem -inform PEM -out servercert.der -outform DER
12.iOS项目中添加servercert.der
13.let sslsock = SSLSocketLite(inHost: "localhost", inPort: 1678)
14.异常域 -> +localhost
15.openssl s_server -key serverkey.pem -cert servercert.pem -accept 1678

【问题讨论】：
-
openssl req -x509 ...- 创建证书时使用的主机名是什么？ Objective C 代码中使用的host, port是什么？另请参阅How do you sign Certificate Signing Request with your Certification Authority 和How to create a self-signed certificate with openssl?，它提供了大量有关 X.509 服务器证书的背景信息，以及各种规则的来源。 -
@jww 谢谢。我按照How do you sign Certificate Signing Request with your Certification Authority 中所说的做了一切，之后我转换了证书：
openssl x509 -in servercert.pem -inform PEM -out servercert.der -outform DER，在 iOS 应用程序中添加了 servercert.der 并启动了sudo openssl s_server -key serverkey.pem -cert servercert.pem -accept 1678。但是在 iOS 端得到了SSLHandshake failed (-9807)，在 OS X 服务器端没有。我做错了什么？ -
如果 X.509 和证书和主机名都正常，那么接下来转到这个：
sudo openssl s_server ...- 您使用的是 Apple 的 OpenSSL 0.9.8 吗？如果是这样，您可能必须使用 OpenSSL 1.0.1 或更高版本。 OpenSSL 1.0.2 将是一个不错的选择。 -
如果您使用的是 OpenSSL 1.0.1 或更高版本，请注意 Apple 的
SecureTransport/ECDHE-ECDSA错误。它在许多 iOS 和 OS X 主机上未打补丁。另请参阅 OpenSSL wiki 上的SSL_OP_SAFARI_ECDHE_ECDSA BUG。 -
@jww
openssl version输出：OpenSSL 0.9.8zg 14 July 2015。我使用自制软件安装了 openssl，所以我需要安装其他供应商的版本吗？您确定我之前评论中的所有命令都有效吗？在服务器端使用pem版本的servercert 和在客户端使用der可以吗？
