SecKeyRef to NSData - xcode

this is my code to generate a new keypair
//Create RSA Key Pair
CFMutableDictionaryRef parameters = CFDictionaryCreateMutable(
kCFAllocatorDefault,
0,
&kCFTypeDictionaryKeyCallBacks,
&kCFTypeDictionaryValueCallBacks);
CFDictionarySetValue(parameters, kSecAttrKeyType, kSecAttrKeyTypeRSA);
int32_t rawnum = 2048;
CFNumberRef num = CFNumberCreate(kCFAllocatorDefault,
kCFNumberIntType, &rawnum);
CFDictionarySetValue(parameters,
kSecAttrKeySizeInBits,
num);
publicKey = NULL;
privateKey = NULL;
SecKeyGeneratePair(parameters, &publicKey, &privateKey);
and i've tried to get the data using this method
- (NSData *)getRSAKeyBitsFromKey:(SecKeyRef)givenKey {
static const uint8_t publicKeyIdentifier[] = "com.company";
NSData *publicTag = [[NSData alloc] initWithBytes:publicKeyIdentifier length:sizeof(publicKeyIdentifier)];
OSStatus sanityCheck = noErr;
NSData * publicKeyBits = nil;
NSMutableDictionary * queryPublicKey = [[NSMutableDictionary alloc] init];
[queryPublicKey setObject:(__bridge id)kSecClassKey forKey:(__bridge id)kSecClass];
//[queryPublicKey setObject:publicTag forKey:(__bridge id)kSecAttrApplicationTag];
[queryPublicKey setObject:(__bridge id)kSecAttrKeyTypeRSA forKey:(__bridge id)kSecAttrKeyType];
// Temporarily add key to the Keychain, return as data:
NSMutableDictionary * attributes = [queryPublicKey mutableCopy];
[attributes setObject:(__bridge id)givenKey forKey:(__bridge id)kSecValueRef];
[attributes setObject:#YES forKey:(__bridge id)kSecReturnData];
CFTypeRef result;
sanityCheck = SecItemAdd((__bridge CFDictionaryRef) attributes, &result);
if (sanityCheck == errSecSuccess) {
publicKeyBits = CFBridgingRelease(result);
// Remove from Keychain again:
(void)SecItemDelete((__bridge CFDictionaryRef) queryPublicKey);
}
return publicKeyBits;
}
I know that probably i didn't set the PublicKeyIdentifier and the other attributes (should i had to?).

macOS SearchKit CoreService found nothing

im working on an that search in the content of allot of files, i planed to use SearchKit but i can't figure out to make Apple's sample code to work, and i can't find any other ressources (NSHipster code didn't work either), here's my code:
#define kSearchMax 1000
#interface ViewController()
#property(nonatomic) SKIndexRef mySKIndex;
#end
#implementation ViewController
#synthesize mySKIndex;
- (void)viewDidLoad {
[super viewDidLoad];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{
[self openIndex];
[self addDoc];
SKIndexFlush(self.mySKIndex);
// i thought that the indexation may need some time ..
sleep(2);
dispatch_async(dispatch_get_main_queue(), ^{
[self searchterm:#"var"];
});
});
}
- (void) openIndex {
NSString *path = [[NSHomeDirectory() stringByAppendingPathComponent:#"index"] stringByAppendingPathExtension:#"txt"]; // 1
NSURL *url = [NSURL fileURLWithPath:path];
NSString *name = #"extension_index";
if ([name length] == 0) name = nil;
SKIndexType type = kSKIndexInverted;
if ([[NSFileManager defaultManager] fileExistsAtPath:path]) {
mySKIndex = SKIndexOpenWithURL ((__bridge CFURLRef) url,
(__bridge CFStringRef) name,
true
);
}else{
self.mySKIndex = SKIndexCreateWithURL((__bridge CFURLRef) url,
(__bridge CFStringRef) name,
(SKIndexType) type,
(CFDictionaryRef) NULL);
}
}
- (void) addDoc {
SKLoadDefaultExtractorPlugIns ();
NSString *path = [NSBundle.mainBundle pathForResource:#"Products" ofType:#"rtf"]; // 1
NSURL *url = [NSURL fileURLWithPath: path]; // 2
SKDocumentRef doc = SKDocumentCreateWithURL ((__bridge CFURLRef) url);
NSString *mimeTypeHint = #"text/rtf";
BOOL added = SKIndexAddDocument ((SKIndexRef) mySKIndex,
(SKDocumentRef) doc,
(__bridge CFStringRef)mimeTypeHint,
(Boolean) true
);
NSLog(added ? #"added" : #"not added");
}
- (void) searchterm:(NSString*)query{
SKSearchOptions options = kSKSearchOptionDefault;
BOOL more = YES;
UInt32 totalCount = 0;
SKSearchRef search = SKSearchCreate (mySKIndex,
(__bridge CFStringRef) query,
options);
while (more) {
SKDocumentID foundDocIDs [kSearchMax];
float foundScores [kSearchMax];
float *scores;
Boolean unranked =
options & kSKSearchOptionNoRelevanceScores;
if (unranked) {
scores = NULL;
} else {
scores = foundScores;
}
CFIndex foundCount = 0;
more = SKSearchFindMatches (
search,
kSearchMax,
foundDocIDs,
scores,
100,
&foundCount
);
NSLog(#"%#", [NSString stringWithFormat:#"current count = %i", totalCount]);
totalCount += foundCount;
}
}
#end
it always print "current count = 0" and the loop is executed only one time.

Since iOS8, unable to load image properties such as EXIF

My code was working great on iOS7.x. But since I compile for iOS 8, it does no longer retrieve others information than basic ones. Here is the only information I get now (no more DateTime, Artist, Model etc.):
{
ColorModel = RGB;
DPIHeight = 72;
DPIWidth = 72;
Depth = 8;
Orientation = 1;
PixelHeight = 2448;
PixelWidth = 3264;
"{Exif}" = {
ColorSpace = 1;
PixelXDimension = 3264;
PixelYDimension = 2448;
};
"{JFIF}" = {
DensityUnit = 1;
JFIFVersion = (
1,
0,
1
);
XDensity = 72;
YDensity = 72;
};
"{TIFF}" = {
Orientation = 1;
};
}
My code is as follows:
-(NSDictionary*)getExif:(NSURL*)assetURL asset:(ALAssetRepresentation *)image_representation {
// create a buffer to hold image data
uint8_t *buffer = (Byte*)malloc(image_representation.size);
NSUInteger length = [image_representation getBytes:buffer fromOffset: 0.0 length:image_representation.size error:nil];
if (length != 0) {
// buffer -> NSData object; free buffer afterwards
NSData *adata = [[NSData alloc] initWithBytesNoCopy:buffer length:image_representation.size freeWhenDone:YES];
// identify image type (jpeg, png, RAW file, ...) using UTI hint
NSDictionary* sourceOptionsDict = [NSDictionary dictionaryWithObjectsAndKeys:(id)[image_representation UTI],kCGImageSourceTypeIdentifierHint,nil];
// create CGImageSource with NSData
CGImageSourceRef sourceRef = CGImageSourceCreateWithData((__bridge CFDataRef) adata,
(__bridge CFDictionaryRef) sourceOptionsDict);
// get imagePropertiesDictionary
CFDictionaryRef imagePropertiesDictionary = CGImageSourceCopyPropertiesAtIndex(sourceRef,0, NULL);
NSLog(#"image props: %#",imagePropertiesDictionary);
CFDictionaryRef propsRef = (CFDictionaryRef)CFDictionaryGetValue(imagePropertiesDictionary, #"{TIFF}");
NSDictionary *props = (__bridge NSDictionary*)propsRef;
NSMutableDictionary *d = [[NSMutableDictionary alloc] init];
NSString * make = nil;
NSString *model = nil;
NSString *
s = [props objectForKey:#"DateTime" ]; if (s) [d setObject: s forKey:#"DateTime"];
s = [props objectForKey:#"Artist" ]; if (s) [d setObject:[s capitalizedString] forKey:#"Artist"];
s = make = [props objectForKey:#"Make" ]; if (s) [d setObject:s forKey:#"Make"];
s = model = [props objectForKey:#"Model" ]; if (s) {
if (make ) s = [s stringByReplacingOccurrencesOfString:make withString:#""];
[d setObject:s forKey:#"Model"];
}
// etc.
IOS8. Photos application bug?
I think it's a bug of Photos.Framework .Because I can get fully metadata when fetch all PHAssets,but lost some information when I fetch the PHAsset by collection.

How do I check whether an NSData object contains a sub-NSData?

I have an NSData object which contains some data I need. What I wanted to do is to find out the position of data "FF D8" (start of JPEG data)
How can I achieve work like this?
First get the range, then get the data:
// The magic start data object is only created once safely and
// then reused each time
static NSData* magicStartData = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
static const uint8_t magic[] = { 0xff, 0xd8 };
magicStartData = [NSData dataWithBytesNoCopy:(void*)magic length:2 freeWhenDone:NO];
});
// assume data is the NSData with embedded data
NSRange range = [data rangeOfData:magicStartData options:0 range:NSMakeRange(0, [data length])];
if (range.location != NSNotFound) {
// This assumes the subdata doesn't have a specific range and is just everything
// after the magic, otherwise adjust
NSData* subdata = [data subdataWithRange:NSMakeRange(range.location, [data length] - range.location)];
}
Try NSData rangeOfData:options:range::
NSData *data = /* Your data here */;
UInt8 bytes_to_find[] = { 0xFF, 0xD8 };
NSData *dataToFind = [NSData dataWithBytes:bytes_to_find
length:sizeof(bytes_to_find)];
NSRange range = [data rangeOfData:dataToFind
options:kNilOptions
range:NSMakeRange(0u, [data length])];
if (range.location == NSNotFound) {
NSLog(#"Bytes not found");
}
else {
NSLog(#"Bytes found at position %lu", (unsigned long)range.location);
}

Listing entries in a keychain on Mac OS X

I have been playing around with Cocoa for the last couple of days and I was wondering how I would go about listing all Name/Account pairs of a keychain that I created? the little key chain access app that comes with Mac OS X does that, so it must be possible I presume? Is SecItemCopyMatching what I'm looking for? How do I specify the keychain I want to search, though? And what's a service name in this context?
...am I the only one who thinks the Keychain API in Cocoa is absolutely horrible? I have been reading the documentation up and down for the last couple of hours or so and I'm still getting nowhere :-/
you iterate over the items in your keychain with SecItemCopyMatching and access the password with SecKeychainFindInternetPassword or SecKeychainFindGenericPassword.
Iterate over Keychain:
// iterates over keychain and pass every item found by the query to PrintAccount.
static void IterateOverKeychain() {
// create query
CFMutableDictionaryRef query = CFDictionaryCreateMutable(kCFAllocatorDefault, 3, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks);
CFDictionaryAddValue(query, kSecReturnAttributes, kCFBooleanTrue);
CFDictionaryAddValue(query, kSecMatchLimit, kSecMatchLimitAll);
CFDictionaryAddValue(query, kSecClass, kSecClassInternetPassword);
// get search results
CFArrayRef result = nil;
OSStatus status = SecItemCopyMatching(query, (CFTypeRef*)&result);
assert(status == 0);
// do something with the result
CFRange range = CFRangeMake(0, CFArrayGetCount(result));
CFArrayApplyFunction(result, range, PrintAccount, nil);
}
// prints the password for a item from the keychain.
static void PrintAccount(const void *value, void *context) {
CFDictionaryRef dict = value;
CFStringRef acct = CFDictionaryGetValue(dict, kSecAttrAccount);
NSLog(#"%#", acct);
}
Print Password:
static void PrintPassword() {
const char *acct = "foo.bar#googlemail.com";
UInt32 acctLen = (UInt32)strlen(acct);
const char *srvr = "calendar.google.com";
UInt32 srvrLen = (UInt32)strlen(srvr);
UInt32 pwLen = 0;
void *pw = 0;
SecKeychainFindInternetPassword(nil, srvrLen, srvr, 0, nil, acctLen, acct, 0, nil, 0, kSecProtocolTypeAny, kSecAuthenticationTypeAny, &pwLen, &pw, nil);
CFStringRef pwString = CFStringCreateWithBytes(kCFAllocatorDefault, pw, pwLen, kCFStringEncodingUTF8, NO);
NSLog(#"%s %#", acct, pwString);
}
Well, I managed to enumerate over the keychain entries, however the password field is empty. I thought if authorization was required, the program would ask for the keychain password automatically like it usually does?
NSDictionary *query = [NSDictionary dictionaryWithObjectsAndKeys:
(id)kSecClassInternetPassword, kSecClass,
(id)kCFBooleanTrue, kSecReturnData,
(id)kCFBooleanTrue, kSecReturnAttributes,
kSecMatchLimitAll, kSecMatchLimit,
nil];
NSArray *itemDicts = nil;
OSStatus status = SecItemCopyMatching((CFDictionaryRef)query, (CFTypeRef *)&itemDicts);
if (status)
[MessageBox Show:(NSString*)SecCopyErrorMessageString(status, NULL)];
NSMutableArray *arr = [[NSMutableArray alloc] init];
for (NSDictionary *itemDict in itemDicts) {
NSData *data = [itemDict objectForKey:(id)kSecValueData];
NSString *pwd = [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease];
NSString *acc = [itemDict objectForKey:(id)kSecAttrAccount];
NSString *name = [itemDict objectForKey:(id)kSecAttrLabel];
if(acc != nil) {
NSArray *values = [NSArray arrayWithObjects: (id)name, (id)acc, (id)pwd, nil];
[arr addObject:(id)values];
}
}
[itemDicts release];
NSInteger c = arr.count;
NSString *cnt = [NSString stringWithFormat:#"%d", c];
[MessageBox Show: [arr objectAtIndex:10]];
