我是Objective-c和iOS编程的新手。
我需要使用REST API,其中请求需要使用x509 PEM证书文件和证书密码进行相互SSL身份验证。
我的问题是我真的不知道如何在目标C中做到这一点,在C#中它会像以下一样简单:
X509Certificate2 myCertificate = new x509Certificate2(certificatePath, certificatePassword);
myRequest.ClientCertificate.Add(myCertificate);
其中"myRequest"
只表示http请求的变量。
我一直在很多论坛和帖子中寻找一段时间,包括一些旧的stackoverflow问题。 人们给出的主要提示是“使用OpenSSL”,但我已经在很少的地方读过(我认为即使在stackoverflow问题中),Apple已经弃用了OpenSSL。
问题:如何使用密码加载.pem x509证书,以使用Objective-C语言将POST请求发送到外部REST API服务?
谢谢。
答案 0 :(得分:0)
我自己的解决方案:
使用OpenSSL命令转换.pem文件介绍pkcs12证书:
openssl pkcs12 -export -in "certificateFile" -inkey "KeyFile" -out "certificate.p12"
然后设置本教程中的一些代码:https://vanjakom.wordpress.com/tag/nsurlconnection/
基本上:
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
NSLog(@"Authentication challenge");
// load cert
NSString *path = [[NSBundle mainBundle] pathForResource:@"userA" ofType:@"p12"];
NSData *p12data = [NSData dataWithContentsOfFile:path];
CFDataRef inP12data = (__bridge CFDataRef)p12data;
SecIdentityRef myIdentity;
SecTrustRef myTrust;
OSStatus status = extractIdentityAndTrust(inP12data, &myIdentity, &myTrust);
SecCertificateRef myCertificate;
SecIdentityCopyCertificate(myIdentity, &myCertificate);
const void *certs[] = { myCertificate };
CFArrayRef certsArray = CFArrayCreate(NULL, certs, 1, NULL);
NSURLCredential *credential = [NSURLCredential credentialWithIdentity:myIdentity certificates:(__bridge NSArray*)certsArray persistence:NSURLCredentialPersistencePermanent];
[[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
}
和
OSStatus extractIdentityAndTrust(CFDataRef inP12data, SecIdentityRef *identity, SecTrustRef *trust)
{
OSStatus securityError = errSecSuccess;
CFStringRef password = CFSTR("userA");
const void *keys[] = { kSecImportExportPassphrase };
const void *values[] = { password };
CFDictionaryRef options = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);
CFArrayRef items = CFArrayCreate(NULL, 0, 0, NULL);
securityError = SecPKCS12Import(inP12data, options, &items);
if (securityError == 0) {
CFDictionaryRef myIdentityAndTrust = CFArrayGetValueAtIndex(items, 0);
const void *tempIdentity = NULL;
tempIdentity = CFDictionaryGetValue(myIdentityAndTrust, kSecImportItemIdentity);
*identity = (SecIdentityRef)tempIdentity;
const void *tempTrust = NULL;
tempTrust = CFDictionaryGetValue(myIdentityAndTrust, kSecImportItemTrust);
*trust = (SecTrustRef)tempTrust;
}
if (options) {
CFRelease(options);
}
return securityError;
}
