需要加密AES256

Question

如何通過iso10126padding和CBC模式加密AES 256中的NSDATA，需要像android的密碼那樣做。請幫助用AES256加密來做NSData的加密。

轉到這個問題，它會幫助你：AES Encryption for an NSString on the iPhone

或轉到：https://github.com/RNCryptor/RNCryptor

在Objective-C

對象 -

// 
// 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];

您可以設置屬性爲可變形並使用您自己的Transformer類來應用加密/解密。

這是一個指南，可轉換的屬性： enter link description here
