iOS RSA的加密和签名

    HBRSAHandler* handler = [HBRSAHandler new];
    
    //加密
    NSString *PublicFilePath = [[NSBundle mainBundle] pathForResource:@"serverPubKey.pem" ofType:nil];
    [handler importKeyWithType:KeyTypePublic andPath:PublicFilePath];//加载公钥
    NSString *test = @"需要加密的数据";
    test = [handler encryptWithPublicKey:test];
    NSLog(@"加密结果 =%@",test);
    
    //签名
    NSString *privateKeyFilePath = [[NSBundle mainBundle] pathForResource:@"clientPriKey.pem" ofType:nil];
    [handler importKeyWithType:KeyTypePrivate andPath:privateKeyFilePath];//加载私钥
    NSString *xml = @"this is test message!";
    xml = [handler signString:xml];
    NSLog(@"签名结果：%@",xml);
