Currently, the RSA algorithm calls qm_crypto_bin_to_hpre_bin() to transfer the key when sending request. However, the key needs to be transferred only once, repeated transfer may cause data inconsistency with original user's data, resulting in incorrect calculation results.
Therefore, after the key is transferred, the 'dsize' is changed to the 'bsize', When 'disze' and 'bsize' are equal, no transfer is performed.
