Opening STAMP-CERT-SHA256 Files

The STAMP-CERT-SHA256 file type is primarily associated with OpenSSL.

STAMP-CERT-SHA256	File extension: STAMP-CERT-SHA256
	File type:	certificate timestamp file

What is an STAMP-CERT-SHA256 file

STAMP-CERT-SHA256 files mostly belong to OpenSSL. STAMP-CERT-SHA256 files store a SHA256 hash of a digital certificate along with a timestamp.
This file is used to verify that a certificate was valid at a specific time. It does not contain the full certificate but a unique hash value computed with the Secure Hash Algorithm 256 (SHA256).
These files help systems validate digital signatures by ensuring that the certificate has not been altered after it was stamped.
Key details as outlined by FilExt.com include:

Stores a unique SHA256 hash of the certificate

Records the exact time a certificate was stamped

Is used in security processes to confirm certificate integrity

FilExt.com tip: You can open the file with a plain text editor if it is stored as text, or use cryptographic tools like OpenSSL to view and verify its contents. It is not meant to be manually edited.

How to open STAMP-CERT-SHA256 files

You need a suitable software like OpenSSL to open an STAMP-CERT-SHA256 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your STAMP-CERT-SHA256 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a STAMP-CERT-SHA256 file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert STAMP-CERT-SHA256 files:

OpenSSL
See the previous paragraphs to learn more about the main application. STAMP-CERT-SHA256 files are often referred to as OpenSSL data files because this type of file is primarily created or used by this software.
Timestamping Authority Software
A *.STAMP-CERT-SHA256 file stores a SHA256 hash of a digital certificate. This hash acts as a cryptographic fingerprint, uniquely identifying the certificate. These files are primarily used for timestamping certificates, allowing for verification of their validity at a specific point in time. The timestamp helps establish the certificate's existence before a potential compromise or revocation. By recording the SHA256 hash alongside a trusted timestamp, the integrity and non-repudiation of the certificate at that particular moment are preserved. This mechanism is crucial for demonstrating compliance, auditing, and legal purposes, ensuring that a certificate's state at a given time can be reliably proven. This file format is classified as Security.

How to solve problems with STAMP-CERT-SHA256 files

Associate the STAMP-CERT-SHA256 file extension with the correct application.
Update your software that should actually open certificate timestamp files. Because only the current version supports the latest STAMP-CERT-SHA256 file format. Search, therefore, e.g. on the manufacturer website after an available OpenSSL update.
To make sure that your STAMP-CERT-SHA256 file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
