如何在 Objective-C 中硬编码 .cer 证书？
How to hardcode .cer certificate in Objective-C?
我一直在尝试使用为所需功能构建本机代码的插件为混合应用程序实施 SSL Pinning。
在生成的本机项目中，Objective-C 代码包含以下函数，用于从 www/certificates 位置读取证书文件 (X.509 DER .cer)。
// AFSecurityPolicy.m
+ (NSSet *)certificatesInBundle:(NSBundle *)bundle {
NSArray *paths = [bundle pathsForResourcesOfType:@"cer" inDirectory:@"www/certificates"];
NSMutableSet *certificates = [NSMutableSet setWithCapacity:[paths count]];
for (NSString *path in paths) {
NSData *certificateData = [NSData dataWithContentsOfFile:path];
[certificates addObject:certificateData];
}
return [NSSet setWithSet:certificates];
}
但是由于插件中的一个已知错误，该位置不会自动创建（理想情况下应该自动创建）。作为解决方法，我想将 .cer 证书内容硬编码到上述函数中。
我该怎么做？
（以上代码的修改版本会很有帮助）
示例证书可以在 Github 上找到 here。

您可以使用字符串来存储证书的 base64 表示形式（也称为 PEM 格式）并将其转换为 NSData:

NSData *data = [NSData dataFromBase64String:originalString];
由于上面的证书是public并且是X.509 DER .cer格式，执行以下操作将其存储为NSData.
NSURL *url = [NSURL URLWithString:@"https://github.com/ashenwgt/ionic-capacitor-ssl-pinning/blob/master/certificates/reqres-cert.cer?raw=true"];
NSData *data = [NSData dataWithContentsOfURL:url];
要将其转换为有效字符串，您可以记录 NSData 的值并复制如下输出。
NSLog(@"[LOG] CERT data from URL: %@", data);
现在您可以将证书分配为字符串，最终代码将只有以下两行（我仅使用上述步骤将证书作为有效字符串获取到硬编码）。

NSData *data = [certString dataUsingEncoding:NSUTF8StringEncoding];
我一直在尝试使用为所需功能构建本机代码的插件为混合应用程序实施 SSL Pinning。
在生成的本机项目中，Objective-C 代码包含以下函数，用于从 www/certificates 位置读取证书文件 (X.509 DER .cer)。
// AFSecurityPolicy.m
+ (NSSet *)certificatesInBundle:(NSBundle *)bundle {
NSArray *paths = [bundle pathsForResourcesOfType:@"cer" inDirectory:@"www/certificates"];
NSMutableSet *certificates = [NSMutableSet setWithCapacity:[paths count]];
for (NSString *path in paths) {
NSData *certificateData = [NSData dataWithContentsOfFile:path];
[certificates addObject:certificateData];
}
return [NSSet setWithSet:certificates];
}
但是由于插件中的一个已知错误，该位置不会自动创建（理想情况下应该自动创建）。作为解决方法，我想将 .cer 证书内容硬编码到上述函数中。
我该怎么做？
（以上代码的修改版本会很有帮助）
示例证书可以在 Github 上找到 here。

您可以使用字符串来存储证书的 base64 表示形式（也称为 PEM 格式）并将其转换为 NSData:

NSData *data = [NSData dataFromBase64String:originalString];
由于上面的证书是public并且是X.509 DER .cer格式，执行以下操作将其存储为NSData.
NSURL *url = [NSURL URLWithString:@"https://github.com/ashenwgt/ionic-capacitor-ssl-pinning/blob/master/certificates/reqres-cert.cer?raw=true"];
NSData *data = [NSData dataWithContentsOfURL:url];
要将其转换为有效字符串，您可以记录 NSData 的值并复制如下输出。
NSLog(@"[LOG] CERT data from URL: %@", data);
现在您可以将证书分配为字符串，最终代码将只有以下两行（我仅使用上述步骤将证书作为有效字符串获取到硬编码）。
