用OC封装系统提供的接口实现RSA加密、解密、签名、验证
CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like HKRSA in your projects. You can install it with the following command:
$ gem install cocoapodsTo integrate HKRSA into your Xcode project using CocoaPods, specify it in your Podfile
7120
:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '7.0'
pod 'HKRSA'Then, run the following command:
$ pod install####USAGE #####加密、解密
HKRSA *rsa = [HKRSA sharedInstance];
[rsa loadPKFromFile:[[NSBundle mainBundle] pathForResource:@"public_key" ofType:@"der"]];
[rsa loadSKFromFile:[[NSBundle mainBundle] pathForResource:@"private_key" ofType:@"p12"] password:@"123456"];
NSString *rawString = @"CFNumberRef keySize = CFNumberCreate(kCFAllocatorDefault, kCFNumberSInt32Type, &iKeySize);";
NSString *encryString = [rsa encryptString:rawString];
NSString *decryptString = [rsa decryptString:encryString];
if (![rawString isEqualToString:decryptString]) {
NSLog(@"加解密 failed");
}#####签名、验证
HKRSA *rsa = [HKRSA sharedInstance];
[rsa loadPKFromFile:[[NSBundle mainBundle] pathForResource:@"public_key" ofType:@"der"]];
[rsa loadSKFromFile:[[NSBundle mainBundle] pathForResource:@"private_key" ofType:@"p12"] password:@"123456"];
NSString *rawString = @"CFNumberRef keySize = CFNumberCreate(kCFAllocatorDefault, kCFNumberSInt32Type, &iKeySize);";
NSString *signedString = [rsa signString:rawString withAbstractType:HKAbstractType_SHA384];
BOOL result = [rsa verifyString:rawString withSignature:signedString withAbstractType:HKAbstractType_SHA384];
if (!result) {
NSLog(@"签名 failed");
