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],
