Base32 Additions for Objective-C on Mac OS X and iOS

Usage

Open the Xcode project file, and drag MF_Base32Additions.m/.h into your project.

In files where you want to use Base32 encoding/decoding, simply include the header file and use one of the provided NSData or NSString additions.

Example use:

#import "MF_Base32Additions.h"

NSString *helloWorld = @"Hello World";
NSString *helloInBase32 = [helloWorld base32String];
NSString *helloDecoded = [NSString stringFromBase32String:helloInBase32];

Performance

  • Encoding: Approximately 4 to 5 times faster than using the equivalent SecTransform.
  • Decoding: Slightly faster but almost identical decoding time as equivalent SecTransform.

Requirements

  • Compile with Automatic Reference Counting
  • Compatible with Mac OSX 10.6+ and iOS 4.0+
