Extract text from App package signatures (P7X)
To convert P7X Signatures to another format, you need SignTool or other System software.
To convert other file formats to the "Digital Signature" file type, you need software like SignTool or a similar tool.
A .P7X file is a Packed Digital Signature file primarily used within the Microsoft Windows ecosystem to authenticate APPX and MSIX application packages. Technically, it adheres to the PKCS #7 cryptographic standard, acting as a container that holds the digital signature and the certificate chain required to verify that an application has not been tampered with since it was signed by the developer.
While essential for system security, .P7X files are notoriously difficult for users to interact with directly. Because they are binary blocks of cryptographic data, you cannot simply double-click them to view the signer's identity or expiration date in a text editor like Notepad. They often appear as mysterious artifacts alongside installer bundles, leaving users unsure if they are critical data or temporary junk. To extract the actual certificate for import or to read the signature details (such as the signer's name and timestamp), you typically need command-line tools like SignTool or complex OpenSSL commands.
For most users, the pragmatic solution is converting the file. If you need to import the certificate into a trust store, converting to CER or PEM is the standard workflow. If you simply want to verify who signed a file without launching a terminal, converting to TXT provides a human-readable decode of the signature attributes.
Convert.Guru analyzes your P7X file, detects the exact format, and lets you read the text inside.
Users also converted PRI, XML, DLL, SF, SIGN and BISIGN files.
If you want to convert P7X file to BASE64, HEX, BIN, ENC, CRYPT, AES, DES, RSA, PGP, GPG, ASC or KEY, you can use SignTool or similar software from the "App Package Signature" category. In the File menu, look for Save As… or Export….
To convert CER, BIN, PEM, DER, KEY, P7S, PFX, ENC, P12, BASE64, P7B or HEX files to P7X, try SignTool or another comparable tool in the "App Package Signature" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our P7X converter.
