Macro Definition Documentation

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

GWEN_Crypt_KeyRsa_GeneratePair()

GWENHYWFAR_API int GWEN_Crypt_KeyRsa_GeneratePair	(	unsigned int	nbytes,
		int	use65537e,
		GWEN_CRYPT_KEY **	pPubKey,
		GWEN_CRYPT_KEY **	pSecretKey )

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

References GWEN_DEPRECATED, and GWENHYWFAR_API.

GWEN_Crypt_KeyRsa_GeneratePair2()

GWENHYWFAR_API GWEN_DEPRECATED int GWEN_Crypt_KeyRsa_GeneratePair2	(	unsigned int	nbits,
		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

Deprecated

Please use GWEN_Crypt_KeyRsa_GeneratePair instead since nbits should be a multiple of 8 anyway according to Libgcrypt.
