我已经解决了将XML RSA私钥转换为PEM文件的问题,但是我遇到另一个问题,即在导入P12私钥时我得到空数据.以下是我的步骤:

1. 将PEM文件转换为P12文件

   openssl> pkcs12 -export -in rsa.pem -inkey rsa.pem -out rsa.p12 -nocerts

2. 将P12文件读入iOS项目

   NSString *path = [[NSBundle bundleForClass:[self class]]    
                       pathForResource:@"MyPrivateKey" ofType:@"p12"];
   NSData *p12data = [NSData dataWithContentsOfFile:path];
   if (![self getPrivateKeyRef]) 
       RSAPrivateKey = getPrivateKeywithRawKey(p12data);

3. 导入P12私钥

   SecKeyRef getPrivateKeywithRawKey(NSData *pfxkeydata)
   { 
       NSMutableDictionary * options = [[[NSMutableDictionary alloc] init] autorelease];
   
       // Set the public key query dictionary
       //change to your .pfx  password here 
       [options setObject:@"MyPassword" forKey:(id)kSecImportExportPassphrase];
   
       CFArrayRef items = CFArrayCreate(NULL, 0, 0, NULL);
   
       OSStatus securityError = SecPKCS12Import((CFDataRef) pfxkeydata,
                                                (CFDictionaryRef)options, &items);
   
       CFDictionaryRef identityDict = CFArrayGetValueAtIndex(items, …
