ios – RNCryptor不使用JSON字符串

注意：我正在使用Matt gallagher的NSData Base64类别找到here(在页面底部)

-(Nsstring*)encryptString:(Nsstring*)plaintext withKey:(Nsstring*)key error:(NSError**)error{
    NSData *data = [plaintext dataUsingEncoding:NSUTF8StringEncoding];
    NSData *encryptionKey = [NSData dataFromBase64String:key];
    NSData *IV = [NSData dataFromBase64String:ENCRYPTION_IV];

    RNCryptorEngine *engine = [[RNCryptorEngine alloc] initWithOperation:kCCEncrypt settings:kRNCryptorAES256Settings key:encryptionKey IV:IV error:error];
    [engine addData:data error:error];
    NSData *encryptedData = [engine finishWithError:error];

    Nsstring *based64Encrypted = [encryptedData base64EncodedString];
    NSLog(@"Encrytped: %@",based64Encrypted);
    return based64Encrypted;
}
-(Nsstring*) decryptString:(Nsstring*)cipherText withKey:(Nsstring*)key error:(NSError**)error;{
    NSData *data = [NSData dataFromBase64String:cipherText];
    NSData *encryptionKey = [NSData dataFromBase64String:key];
    NSData *IV = [NSData dataFromBase64String:ENCRYPTION_IV];

    RNCryptorEngine *engine = [[RNCryptorEngine alloc] initWithOperation:kCCDecrypt settings:kRNCryptorAES256Settings key:encryptionKey IV:IV error:error];
    [engine addData:data error:error];
    NSData *decryptedData = [engine finishWithError:error];
    Nsstring *decryptedString = [[Nsstring alloc] initWithData:decryptedData encoding:NSUTF8StringEncoding];
    NSLog(@"Decrypted: %@",decryptedString);
    return decryptedString;
}

当我使用像hello world这样的字符串时,它可以正常工作.当我使用像{“username”：“开发人员”,“密码”：“abcdefG * 12”这样的字符串时,我想它与编码有关,但我真的知道要使用什么.

当我加密该字符串时,我得到一个base64字符串,当我尝试解密时,我得到一个空字符串.

UPDATE

由于：在json字符串中,它看起来像是失败了.
更奇怪的是,它只是失败,字符串是json格式,我认为是：因为我先尝试过,但经过进一步的调查,如果我破坏了任何JSON要求,它的停止工作.它适用于RNEncryptor但是我不确定我做错了什么.无论哪种方式,我认为我们可能会重新设计当前的流量

更新2

这是我调用这些方法的地方：

NSDictionary *credentials = @{@"username":@"developer",@"password":@"abcdefG*12"};
Nsstring *jsonString = [ credentials JSONStringWithOptions:JKSerializeOptionNone error:&error];
NSLog(@"json string: %@",jsonString); //OUTPUTS: {"username":"developer","password":"abcdefG*12"}
CCGEncryption *encryptionObject = [[CCGEncryption alloc] init]; //THIS IS THE OBJECT WHERE THE encrypt/decrypt methods are

Nsstring *encrypted = [encryptionObject encryptString:jsonString withKey:ENCRYPTION_KEY error:&error];
if(error){
    NSLog(@"Error:%@",error); //NO ERROR
}
Nsstring *decrypted = [encryptionObject decryptString:encrypted withKey:ENCRYPTION_KEY error:&error];
if(error){
    NSLog(@"Error:%@",error);  //NO ERROR
}
NSLog(@"decrypted: %@",decrypted); //OUTPUT: decrypted:
