需要做加密AES256

Question

如何通过 iso10126padding 和 CBC 模式在 AES 256 中加密 NSDATA，需要像 android.Please 这样的密码来帮助使用 AES256 加密对 NSData 进行加密。

Answer 1

转到这个问题它会对你有所帮助：AES Encryption for an NSString on the iPhone

或转到：https://github.com/RNCryptor/RNCryptor

在Objective-C

Obj-C

//
// Encryption
//
NSString *password = @"Secret password";
RNEncryptor *encryptor = [[RNEncryptor alloc] initWithPassword:password];
NSMutableData *ciphertext = [NSMutableData new];

// ... Each time data comes in, update the encryptor and accumulate some ciphertext ...
[ciphertext appendData:[encryptor updateWithData:data]];

// ... When data is done, finish up ...
[ciphertext appendData:[encryptor finalData]];


//
// Decryption
//
RNDecryptor *decryptor = [[RNDecryptor alloc] initWithPassword:password];
NSMutableData *plaintext = [NSMutableData new];

// ... Each time data comes in, update the decryptor and accumulate some plaintext ...
NSError *error = nil;
NSData *partialPlaintext = [decryptor updateWithData:data error:&error];
if (error != nil) {
    NSLog(@"FAILED DECRYPT: %@", error);
    return;
}
[plaintext appendData:partialPlaintext];

// ... When data is done, finish up ...
NSError *error = nil;
NSData *partialPlaintext = [decryptor finalDataAndReturnError:&error];
if (error != nil) {
    NSLog(@"FAILED DECRYPT: %@", error);
    return;
}

[ciphertext appendData:partialPlaintext];

Answer 2

您可以将属性设置为 Transformable 并使用您自己的 Transformer class 来应用 encryption/decryption。
