View File Certificates

Use this AppControl Manager page to view highly detailed information about the certificates that are embedded in the signed files on your system. This feature will display the complete chains of all of the signers of a signed file.

Tip

This feature allows you to verify the signing certificates in the .CIP files of signed App Control policies as well.

The following data is displayed for each member of the certificate chain:

Name	Description
Signer Number	A unique identifier assigned to the certificate's signer. If the file is signed by multiple certificates, then each of them will have a different number, allowing you to easily differentiate between them.
Type	Specifies the type of certificate: root, intermediate, or leaf.
Subject Common Name	The Common Name (CN) field in the certificate's subject.
Issuer Common Name	The Common Name (CN) field of the certificate's issuer.
Not Before	The starting date and time when the certificate becomes valid.
Not After	The expiration date and time when the certificate is no longer valid.
Hashing Algorithm	The cryptographic algorithm used to create a hash of the certificate's contents.
Serial Number	A unique numeric identifier assigned to the certificate by the issuing Certificate Authority (CA).
Thumbprint	A unique hash value (fingerprint) derived from the entire certificate, used to verify integrity.
TBS Hash	The hash of the "To Be Signed" (TBS) portion of the certificate, ensuring its integrity before signing.
Extension OIDs	Object Identifiers (OIDs) that define optional extensions, such as key usage, policies, or constraints.
