Sign hashes with SMCTL
DigiCert® Signing Manager Controller (SMCTL) is a Command Line Interface (CLI) that facilitates manual and automated private key management, certificate management, and signing with or without the need for human intervention.
Hash signing ensures data integrity by generating unique cryptographic signatures for files, offering an extra layer of security against tampering and unauthorized modifications throughout the software distribution process.
You can integrate third-party signing tools with SMCTL for simplified signing. For other SMCTL commands, refer to the SMCTL command manual.
Suggerimento
SMCTL does not support all characters in sign commands, review the following:
Supported characters:
@ % ( ) - _ = [ ] { } ;
Unsupported characters:
| ` $ > < # ! ' & + ^
Note: Jarsigner supports the
^
character in sign commands.
To avoid errors, remove unsupported characters from file paths before attempting to sign or sign directly via the third party tool.
Prerequisites
SMCTL version 1.44.0 or higher
Keypair and default certificate
Hash to be signed
Download and integrate third-party signing tools
Refer to the article below to identify the third-party signing tools that you require based on your operating system and the types of files you need to sign:
Set PATH environment variables
Operating systems use the environment variable called PATH to determine where executable files are stored on your system. Use the PATH environment variable to store the file path to your signing tools to ensure that the CLI can reference these signing tools.
