| ## sec_psm_sign_data(3sec) Computes the signature of data using a specified signature algorithm. This routine is not available in the DCE binary code. It is provided in DCE source for use by vendors. Synopsis #include <dce/sec_pk_base.h> error_status_t sec_psm_sign_data( sec_psm_handle_t psm_handle, sec_pk_algorithm_id_t *signature_alg_id, sec_pk_usage_flags_t key_usage, sec_pk_gen_data_t *data, unsigned32 *kvno, sec_pk_signed_t *signature, error_status_t *status_t); Parameters Input psm_handle A pointer to an opaque handle to the personal security context data. Use sec_psm_open( ) to obtain the handle. signature_alg_id The ASN.1 DER-encoded object ID of the signature algorithm. MD5WithRSAEncryption is the only algorithm ID currently supported. key_usage A sec_pk_usage_flags_t that contains the usage flag of the private key to be used in this operation. data A pointer to the ASN.1 DER-encoded data to be signed. Output kvno The version of the key being used. signature A pointer to the computed signature. status_t A pointer to the completion status. On successful completion, the routine returns error_status_ok. Otherwise, it returns an error. Description The sec_psm_sign_data( ) routine computes the signature of input data by using the signature algorithm specified by signature_alg_id. This routine allocates memory for the returned signed data. Call the sec_pk_data_free( ) routine to deallocate that memory.
