titleImporting loadable code from a .bin file

Clicking the Import code from a .bin file button located in the top right corner of the Loadable code settings page launches a dialog box for selecting the .bin file from the required project.

Upon importing, GrdUtil.exe reads from the project_name.bmap file settings describing the dongle’s memory occupied by the loadable code. After importing, the following appears in the dialog box:

Status indicatorPurpose

The dialog box is designed for generating, importing and exporting ECC160 key pairs, which are used during the conversion of binary code into GCEXE format (see previous item).

The private and open ECC160 No.2 keys used for verifying the digital signature of encrypted code appear in the top of the dialog box (on the left and on the right, respectively). 

ECC160 No.1 key pair for encrypting the binary code appears in the bottom of the dialog box (private key – to the left, public – to the right).

Additionally, the dialog box is provided with buttons that permit the generation of new key pairs, exporting them into external files for use in applications and importing key pair files from other projects.
