Example: Crypt2.DecryptStringENC method

Demonstrates how to call the DecryptStringENC method. Objective-C

#import <CkoCrypt2.h>
#import <NSString.h>

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoCrypt2 *crypt = [[CkoCrypt2 alloc] init];

crypt.CryptAlgorithm = @"aes";
crypt.CipherMode = @"cbc";
crypt.KeyLength = [NSNumber numberWithInt:128];
[crypt SetEncodedKey: @"000102030405060708090A0B0C0D0E0F" encoding: @"hex"];
[crypt SetEncodedIV: @"000102030405060708090A0B0C0D0E0F" encoding: @"hex"];
crypt.EncodingMode = @"base64";

// Return the base64 encoded encrypted bytes
NSString *encodedEncrypted = [crypt EncryptStringENC: @"Hello World!"];
NSLog(@"%@%@",@"Encrypted: ",encodedEncrypted);

// Output:
// Encrypted: qiq+IFhcjTkEIkZyf31V/g==

// Decrypt
NSString *originalText = [crypt DecryptStringENC: encodedEncrypted];

NSLog(@"%@%@",@"Decrypted: ",originalText);

// Output:
// Decrypted: Hello World!
