Sign Authenticode files with Osslsigncode on Linux

Osslsigncode is a command-line tool used to code sign, timestamp, and verify signatures executable files. Osslsigncode leverages the OpenSSL library for performing code signing operations. Osslsigncode can be compiled on most platforms where OpenSSL and cURL exist.

Follow these instructions to sign directly using Osslsigncode and securely reference your private key stored in DigiCert® Software Trust Manager. Alternatively, integrate Osslsigncode with Signing Manager Controller (SMCTL) for simplified signing.

Sugerencia

DigiCert® Software Trust Manager only supports Osslsigncode signing on Linux.
To sign on Windows or macOS, use Jsign.
To avoid errors when signing large files, use osslsigncode instead of Jsign.

Prerequisites

Sign with Osslsigncode

The downloaded certificate is referred to as cert.pem in the scenarios below.

To sign and timestamp:

osslsigncode sign -pkcs11engine /usr/lib/x86_64-linux-gnu/engines-1.1/libpkcs11.so -pkcs11module /root/smpkcs11.so -certs <path to keypair certificate> -key 'pkcs11:object=<keypair alias>;type=private' -in <file to be signed> -out <output signed file> -h sha256 -t http://timestamp.digicert.com

Command sample:

osslsigncode sign -pkcs11engine /usr/lib/x86_64-linux-gnu/engines-1.1/libpkcs11.so -pkcs11module /root/smpkcs11.so -certs cert.pem -key 'pkcs11:object=keypair;type=private' -in test.msi -out test-signed.msi -h sha256 -t http://timestamp.digicert.com

Command output:

root@dcd6f73b44b0:~# osslsigncode sign     -pkcs11engine /usr/lib/x86_64-linux-gnu/engines-1.1/libpkcs11.so     -pkcs11module /root/smpkcs11.so     -certs cert.pem     -key 'pkcs11:object=keypair;type=private'     -in test.msi -out test-signed.msi -h sha256 -t http://timestamp.digicert.com
Succeeded

Verify signature with Osslsigncode

To verify signature:

osslsigncode verify -in <signed file>
