libMobileGestalt is a library that can be used to get various system values such as the UDID, disk usage, device version and much more. It is comparable to liblockdown.dylib. See also lockdownd.

MGCopyAnswer

// Common form: MGCopyAnswer(CFStringRef string);
CFStringRef value = MGCopyAnswer(kMGDeviceColor);
NSLog(@"Value: %@", value);
CFRelease(value);

MGGetBoolAnswer (iOS 7+)

// bool MGGetBoolAnswer(CFStringRef key);
bool value = MGGetBoolAnswer(CFSTR("UIProceduralWallpaperCapability"));
NSLog(@"Value: %d", value);

Generate Obfuscated Key

char buffer[256] = { 0 };
snprintf(buffer, sizeof(buffer), "%s%s", "MGCopyAnswer", key);

unsigned char md5Hash[CC_MD5_DIGEST_LENGTH] = { 0 };
CC_MD5(buffer, (CC_LONG)strlen(buffer), md5Hash);

NSData *data = [NSData dataWithBytes:md5Hash length:CC_MD5_DIGEST_LENGTH];
NSString *obfuscatedKey = [[data base64EncodedStringWithOptions:0] substringToIndex:22];
