在信任评估的同时不断获得kSecTrustResultRecoverableTrustFailure - iphone

Question

我想与我的服务器安全地沟通,这就是我在做什么......

NSURLProtectionSpace *protectionSpace = [challenge protectionSpace];
SecTrustRef trust = [protectionSpace serverTrust];
NSURLCredential *credential = [NSURLCredential credentialForTrust:trust];

    SecPolicyRef myPolicy = SecPolicyCreateBasicX509();

NSArray * certs = [[NSArray alloc] initWithObjects:(id)certificate,nil]; //certificate is my server's cert.
credential = [NSURLCredential credentialForTrust:trust];

    SecTrustSetAnchorCertificates(trust,
                                  (CFArrayRef) [NSArray arrayWithObject:(id) certificate ]);    

OSStatus status = SecTrustCreateWithCertificates(certs, myPolicy, &trust);

SecTrustResultType trustResult = 0;

if (status == noErr) {
    status = SecTrustEvaluate(trust, &trustResult);
}

    NSLog(@"Trust I get: %d", trustResult);
[certs release];

if (trustResult == kSecTrustResultRecoverableTrustFailure) {
    NSLog(@"Recoverable Failure");
    CFAbsoluteTime trustTime,currentTime,timeIncrement,newTime;
    CFDateRef newDate;

    trustTime = SecTrustGetVerifyTime(trust);             
    timeIncrement = 31536000;                               
    currentTime = CFAbsoluteTimeGetCurrent();              
    newTime = currentTime - timeIncrement;                  
    if (trustTime - newTime){                               
        newDate = CFDateCreate(NULL, newTime);              
        SecTrustSetVerifyDate(trust, newDate);            
        status = SecTrustEvaluate(trust, &trustResult);   
    }
    NSLog(@"Trust again:%d", trustResult);// AGAIN kSecTrustResultRecoverableTrustFailure(5) over here

}

任何人都知道它为什么会发生......似乎它不是关于证书的到期(实际上也不是这样)但可能是原因.

谢谢

Answer 1

SecTrustResultRecoverableTrustFailure 如果发生

• 证书是md5哈希(IOS5)
• 服务器不提供根证书和中间证书
• 设置SecTrustSetAnchorCertificatesOnly(trust,YES),锚证书仅在内置锚证书中
• 证书已过期
• ？

我通过配置webserver来发送整个证书链而不是仅发送服务器证书来解决我的问题.

通过配置我的apache mod_ssl:https: //httpd.apache.org/docs/2.2/mod/mod_ssl.html#sslcertificatechainfile
