Give Feedback Example: Creating a Signed .aocx File Using OpenSSL Manager

Command syntax:

$AOCL_BOARD_PACKAGE_ROOT/linux64/libexec/ -H openssl_manager \
-i <path_to_input_file/input_filename.aocx> -r <rootpublickey.pem> \
 -k <cskkey.pem> -o <path_to_output_file/output_filename.aocx>

Example output, signing vector_add.aocx:

$ $AOCL_BOARD_PACKAGE_ROOT/linux64/libexec/ -H openssl_manager \
-i vector_add.aocx -r ../openssl_keys_1_2_1/key_pr_root_public_key.pem \
-k ../openssl_keys_1_2_1/key_pr_csk2_public_key.pem -o signed_06_vector.aocx 

The script assumes the PACsign and Intel Acceleration Stack environment is setup. If not run the command : <stack_installation_path>/
aocx filename/path=vector_add.aocx
output filename/path=signed_06_vector.aocx
openssl hsm_manager_options=openssl_manager 
input path =.
input filename =vector_add.aocx
output path =.
output filename =signed_06_vector.aocx
Extracted the filename as signed_06_vector 
1. Extracted the bin from the aocx 
2. Extracted the gzip compressed GBS file from the .bin
3. Uncompressed .gz it to get the GBS file
Initiating PACSign tool to sign the GBS. This process will take a couple of minutes...

4. Signed the GBS 
5. Compressed the gbs file 
6. Added the signed gzip file to fpga.bin 
7. Added the fpga.bin file back into aocx file
The signed file signed_06_vector.aocx has been generated. Use the command aocl program <device_name> <filename>.aocx to program it on the FPGA card

The following message indicates that your output signed bitstream is successfully created:
