Question

在我的申请中,我使用了加密和加密。

Before entering the string in to local database, I am encrypting that and after fetching the data from database I am decrypting it and using in my application. It is working fine. I have used encryption/decryption from link below

www.un.org/spanish/ecosoc 在加密时:

    NSString *myKey=@"any string more than 8 char";

    NSData *data ; 
    NSData *encryptedData; 
    NSString *encryptPassword,*encryptPasscode;

    // 1) Encrypt

    data = [password dataUsingEncoding: NSASCIIStringEncoding];
    encryptedData = [data AESEncryptWithPassphrase:myKey];

    // 2) Encode Base 64

    [Base64 initialize];
    encryptPassword = [Base64 encode:encryptedData];

www.un.org/spanish/ecosoc 加密时:

    NSData *decryptedData;
    NSData  *b64DecData;

    field1 = (char *) sqlite3_column_text(selectPasscodeStatement, 0);
    NSString *fieldStr1 = [[NSString alloc] initWithUTF8String: field1];

     // 3) Decode Base 64

      b64DecData = [Base64 decode:fieldStr1];

     // 4) Decrypt

       decryptedData = [b64DecData AESDecryptWithPassphrase:myKey];

       retrivedPasscode = [[NSString alloc] initWithData:decryptedData encoding:NSASCIIStringEncoding];

但是,我已静态地接受了同样的项目。我在另一个项目中利用这一静态图书馆。当我管理该项目时,在加密时,它给我留下了以下错误:

[NSConcrete MutableData] 缩略语

Answer 1

You need to make change in the Build Settings of the project which will link the static library with the main project. Follow these steps:

(1) 铺设地板。

2)Search for “其他联系旗帜”。

3)Add -all_loadcode to it。

4)Build and run the project.

它对我来说是很出色的。

Answer 2

1. 进口类别负责人档案:

#import "NSData-AES.h"

我认为有<代码>。 AESDecodeWithPassphrase methods下定义。如果没有这种说法,则不知道这种方法。

仅澄清一下——在你想要利用这一类别所增加的能力的每一个档案中,你必须输入该类别负责人的档案。
