mbx_sm2_ecpublic_key
Computes a public key.
Syntax
mbx_status mbx_sm2_ecpublic_key_mb8(int64u* pa_pubx[8], int64u* pa_puby[8], int64u* pa_pubz[8], const int64u* const pa_skey[8], int8u* pBuffer);
mbx_status mbx_sm2_ecpublic_key_ssl_mb8(BIGNUM* pa_pubx[8], BIGNUM* pa_puby[8], BIGNUM* pa_pubz[8], const BIGNUM* const pa_skey[8], int8u* pBuffer);

Parameters
pa_pubx |
Array of pointers to the vectors of computed public key x-coordinates. |
pa_puby |
Array of pointers to the vectors of computed public key y-coordinates. |
pa_pubz |
Array of pointers to the vectors of computed public key z-coordinates. |
pa_skey |
Array of pointers to the vectors of private keys. |
pBuffer |
Pointer to the work buffer. |
Description
The function computes public keys using private keys specified by the pa_skey parameter. If z-coordinate of computed public is required (pa_pubz is not NULL), then computed public keys are stored using projective coordinates. If pa_pubz is NULL, then computed public keys are stored using affine coordinates.
The work buffer specified by the pBuffer parameteris not currently used and can be NULL.
Return Values
The mbx_sm2_ecpublic_key() function returns the status that indicates whether the operation completed successfully or not. The status value of 0 indicates that all operations completed successfully. The error condition can be analyzed by the MBX_GET_STS() call.
