◆ GWEN_CRYPT_KEYRSA_FLAGS_DIRECTSIGN

#define GWEN_CRYPT_KEYRSA_FLAGS_DIRECTSIGN 0x00000001

When signing always directly use the signature, do not determine whether (sig-n) is smaller

		int	use65537e,

	)

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.
