armadsen / BuildLibFLAC.sh
Created February 15, 2013 19:52
Quickly thrown together script to build libFLAC as a 64/32-bit universal binary on Mac OS X 10.8.
#!/usr/bin/env bash
# Put this script in the libFLAC source directory, and make sure it's executable (chmod +x BuildLibFlac.sh), then run it (./BuildLibFLAC.sh)
# Note that this was written to be used on 10.8 with Xcode 4.6 and FLAC 1.2.1. It may/will need to be changed for future versions of the OS, tools, and/or FLAC
env CFLAGS="-arch x86_64" CPPFLAGS="-arch x86_64" LDFLAGS="-arch x86_64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk -mmacosx-version-min=10.5" ./configure --disable-asm-optimizations --enable-static --disable-shared --disable-ogg

Last active December 10, 2015 04:28
Complete example/test program for quick and dirty function to determine if a method in an Objective-C protocol is required or optional. Example for my answer to this stackoverflow question: http://stackoverflow.com/questions/14043930/how-to-identify-a-protocol-method-is-optional-during-runtime/14044086#14044086
#import <Foundation/Foundation.h>
#import <objc/runtime.h>
@protocol TestProtocol <NSObject>
@required
- (void)methodA;
@optional
- (void)methodB;
@end

armadsen / PublicKeyDecryptUsingCSSM.m
Last active October 12, 2015 00:55
Demonstrates the use of CSSM for decrypting using a public key, which is not supported by the Security Transforms API on Mac OS X.
NSData *ORSDecryptDataWithPublicKey(NSData *dataToDecrypt, SecKeyRef publicKey)
{
const CSSM_KEY *cssmPubKey = NULL;
SecKeyGetCSSMKey(publicKey, &cssmPubKey);
CSSM_CSP_HANDLE handle;
SecKeyGetCSPHandle(publicKey, &handle);
CSSM_DATA inputData = {
.Data = (uint8_t *)[dataToDecrypt bytes],
.Length = [dataToDecrypt length],
