Define Documentation

#define GWEN_CRYPT_KEYRSA_FLAGS_DIRECTSIGN   0x00000001

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

Creates a key pair and returns a pointer to it.

Returns:
NULL on error, otherwise a pointer to two keys: public and private
Parameters:
nbytesnumber of bytes
use65537e!=0: use the value 65537 for the public exponent, otherwise let the library choose the exponent by its own

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