如何从Objective C中的文件创建私钥? [英] How to create private key from file in Objective C?

问题描述

我已经创建了一个这样的公钥:

I have created a public key like this:

 NSString *pkFilePath = [[NSBundle mainBundle] pathForResource:@"public_key" ofType:@"der"];
NSData *myCertData = [NSData dataWithContentsOfFile:pkFilePath];


SecCertificateRef cert = SecCertificateCreateWithData (kCFAllocatorDefault, (CFDataRef)myCertData);
CFArrayRef certs = CFArrayCreate(kCFAllocatorDefault, (const void **) &cert, 1, NULL);

SecTrustRef trust;
SecPolicyRef myPolicy   = SecPolicyCreateBasicX509();
SecTrustCreateWithCertificates(certs, myPolicy, &trust);
SecTrustResultType trustResult;
SecTrustEvaluate(trust, &trustResult);
SecKeyRef pub_key_leaf = SecTrustCopyPublicKey(trust);
NSLog(@"%@",pub_key_leaf);

但是如何从文件创建私钥?

But how to create private key from file?

这是一些创建私钥的相关代码，但我不知道如何使用我的私钥文件从中创建私钥.

Here is some related code to create a private key but I am not getting how to create private key from this using my privatekey file.

推荐答案

我遇到了同样的问题，原来你需要使用 p12 文件来导入私钥.

I had the same problem, it turns out you need to use a p12 file to import the private key.
