Hello. How can i use this with swift?

Is it generated by:

let o = Obfuscator.newWithSaltUnsafe()
o.hexByObfuscatingString("superNEEDEDstring")

? or how?

Hi there!

I'm currently trying to use Obfuscator-iOS in my app project. However, when building on the iPhone 5 simulator, I'm getting the following linker error:

Hi,

While creating a Obfuscator object I came across an issue where not all my classes are obfuscating the key successfully. For example if I use any of the below set of classes as a salt I always get error Could not obfuscate - Use different salt

Obfuscator *o = [Obfuscator newWithSalt:[NSString class], [NSObject class], [NSString class], nil];
or
//Application is a class define in my project
Obfuscator *o = [Obfuscator newWithSalt:[Application class], [NSString class], nil];
or 
//Rename class from Application to Applicatio
Obfuscator *o = [Obfuscator newWithSalt:[Applicatio class], [NSString class], nil];
or
//Rename class from Application to Applicatin
Obfuscator *o = [Obfuscator newWithSalt: [Applicatin class], [NSObject class], nil];
or
//Protection is a class in my application
Obfuscator *o = [Obfuscator newWithSalt: [Protection class], [NSString class], nil];
or
//Protection is a class in my application
Obfuscator *o = [Obfuscator newWithSalt: [Protection class], [NSObject class], nil];

Whereas below set of classes are acceptable

// Using NSString and NSObject as salt
Obfuscator *o = [Obfuscator newWithSalt:[NSString class], [NSObject class], nil];
or
Obfuscator *o = [Obfuscator newWithSalt:[NSString class], [NSString class], [NSString class], nil];
or
//Rename class from Application to Applicatin
Obfuscator *o = [Obfuscator newWithSalt:[Applicatin class], [NSString class], nil];

I am not sure if any of the character in class name is causing this issue. If there is any limitation in using the specific characters in class name for salt than let me know.

I found a problem with WeChat-related appkey, hexByObfuscatingString methods, such as "wxaa45ad08facad578", "wxaa45ad08uhtad578", I don't know if there is a way to solve it @pjebs

This fixes the issue building with CocoaPods in issue #2.

The #include <CommonCrypto/CommonCrypto.h> line needed to be moved from the header file to the implementation file to remove the build error.

I've tested this in my application and it works as expected.

when trying to obfuscate a web address with a hyphen in it, it returns

2016-06-15 13:27:36.955 Impl.[47263:1595477] Could not obfuscate: http://xxx-xx.xxxxxxxx.xxx/ - Use different salt

any ideas how i can get around this ?

works fine with all my other variables which dont have special characters.

I added Obfuscator-iOS to my project via CocoaPods and followed the directions to obfuscate strings. I'm trying to use hexByObfuscatingString: to obfuscate a secret key for GitHub's API, but I keep getting an error that it could not obfuscate my secret key string.

I walked through the code and I think that the problem is at line number 164 in Obfuscator.m. In the reveal: method, there's this line of code:

*dataPtr = *dataPtr ^ *keyPtr;

The problem that I am seeing is that both *dataPtr and *keyPtr point to the character '8' at one index. Therefore, '8' XOR '8' is going to be byte 0. Because the code is operating on C strings, this '0' byte is prematurely terminating the obfuscated string and the obfuscated version appears to be truncated.

Getting errors: (1) Expected ';' after method prototype (2) Expected identifier

at two method declarations in Obfuscator.h file

• (instancetype)newWithSalt:(Class)class, ... NS_REQUIRES_NIL_TERMINATION; and
• (void)storeKey:(NSString *)key forSalt:(Class)class, ... NS_REQUIRES_NIL_TERMINATION;

Renaming class to some other name fixed the errors.

Hello,

Thanks for this project - looks like it's exactly what I need. I added the Obfustcator.h and Obfuscator.m files to my project manually (i.e., not using Cocoapods).

I'm able to run the example code you had in the README file, and it successfully generates a hex value. When I try to do this with my own strings that I want to obfuscate, I keep getting

"Could not obfuscate [...] Use different salt" logs.

I'm on Xcode 8.3.2

Thanks!

Thank you for this great class.

While using it in my Xcode 10.1 project, it shows the following warning:

Obfuscator.m:173:25: Possible misuse of comma operator here

This is the code:

// If at end of key data, reset count and
// set key pointer back to start of key value
if (++keyIndex == [self.salt length])
    keyIndex = 0, keyPtr = keyData;

I've solved it by splitting the statements over multiple lines within the IF condition:

// If at end of key data, reset count and
// set key pointer back to start of key value
if (++keyIndex == [self.salt length])
{
    keyIndex = 0;
    keyPtr = keyData;
}

Hi,

I am using Obfuscator library in my project. However, I cannot create an Archive for my app because of the following error:

Are there updates/workaround to address this issue other than disabling bitcode on the target level?

Thanks, Kenneth

Hi!

I install it with cocoapods. When i compile my swift project, i have this error :

Could not build Objective-C module 'Obfuscator'

Have you any idea ?
