	)

Creates a key pair and returns a pointer to it.

Returns: NULL on error, otherwise a pointer to two keys: public and private

Parameters

nbytes	number of bytes
use65537e	!=0: use the value 65537 for the public exponent, otherwise let the library choose the exponent by its own

		int	use65537e,
		GWEN_CRYPT_KEY **	pPubKey,
		GWEN_CRYPT_KEY **	pSecretKey
	)

Creates a key pair and returns a pointer to it. This function allows for more precise control over the size of the created key because it lets you specify the size in bits rather than in bytes.

Returns: NULL on error, otherwise a pointer to two keys: public and private

Parameters

nbits	number of bits
use65537e	!=0: use the value 65537 for the public exponent, otherwise let the library choose the exponent by its own
