int GWEN_Crypt_KeyRsa_GeneratePair ( unsigned int  nbytes,

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

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
