problems using SecKeyEncrypt
I'm starting to work with cryptography on the iphone...
at the moment I'm trying to simply encrypt (and later decrypt a string) but ..when I run the app (on the device, an iphone) i get this message: "Program received signal: “EXC_BAD_ACCESS”."
which should mean...possibly problems with memory management right?
here the incriminated part of code:
uint8_t *pPlainText = (uint8_t*)"This is a test";
size_t *iCipherLength = (size_t*)"1024";
status = SecKeyEncrypt( public, kSecPaddingNone, pPlainText,strlen( (char*)pPlainText ) + 1, aCipherText,iCipherLength );
public is a SecKeyRef containing the public key

Glancing at the documentation, aCipherText should be allocated first, and iCipherLength shouldn't be a string. It needs to be a number. Here's an attempt at fixing it (not tested):
uint8_t *pPlainText = (uint8_t*)"This is a test"; uint8_t aCipherText; size_t iCipherLength = 1024; status = SecKeyEncrypt(public, kSecPaddingNone, pPlainText, strlen( (char*)pPlainText ) + 1, aCipherText, &iCipherLength);
