What is P7S Viewer?

P7S Viewer

P7S Viewer is a handy tool for anyone dealing with digital files and documents. If you need to check the details of your signed files, this app has got your back! It allows you to see everything about digitally signed and encrypted files, especially P7S items.

Understanding Digital Signatures

This app helps you focus on individual, digitally signed files so you can view their details. If a file has multiple signatures, P7S Viewer shows you all the instances and info about each one. Pretty neat, right?

View Signature Certificates

With P7S Viewer, you can also peek at a file's signature certificate. This means you'll see which certificate was used to sign that specific document.

Why Are Digital Signatures Important?

You might be wondering why digital signatures matter. Well, they securely verify someone's identity. For instance, you can link a private key with a public one to connect an identity with that key.

The Role of Certificate Authorities

Usually, certificates need to come from a trusted authority based on where you're using them. So if you're signing documents in your company, you'll need a valid certificate from your organization that confirms who you are.

Different Certificate Types

Certificates often come in bundles and have various structures and uses. Generally, signed transactions or files will include info about the signing certificate and who validated that identity.

Supported File Types

P7S Viewer works with three types of signed files: P7S, P7M, and CMS.

P7S vs P7M vs CMS Files

P7S is a data file type usually opened by email management programs. It contains encrypted and signed messages or emails. Then there’s P7M; it represents electronic messages that include sensitive data and attachments—also encrypted and digitally signed!

Lastly, we have CMS (Cryptographic Message Syntax), which is more widely used compared to the other two formats. It’s great for signing and encrypting various types of digital content.

Explore Signature Details Easily!

P7S Viewer lets you upload a file to check out who the digital signature belongs to—like the issuer's name and subject (which could be an individual or an organization). You’ll also find details like the encryption algorithm used, the certificate's status, the name of the signed file, timestamp info, along with when it was signed.
