Extract text from PKCS#7 certificate bundles (P7B)
To convert P7B certificates to another format, you need OpenSSL or other Encoded software.
To convert other file formats to the "Cryptographic Certificate Bundle" file type, you need software like OpenSSL or a similar tool.
The .P7B file format is a Base64 encoded ASCII file used to store public-key cryptography certificates. It is defined by the PKCS#7 standard. Primarily used as a certificate bundle, it typically contains a public X.509 certificate along with its intermediate certificate chain. These files are enclosed between -----BEGIN PKCS7----- and -----END PKCS7----- statements. Administrators frequently manage them using OpenSSL, Microsoft Windows Certificate Services, or Apple Keychain Access. You can read more about the cryptographic syntax on Wikipedia.
Despite being an industry standard, .P7B files present severe limitations in deployment. Most critically, they do not store private keys. This causes significant confusion for users attempting to install SSL certificates on a new server, as the private key is strictly required to complete the installation. Additionally, many popular open-source web servers, including Apache and Nginx, do not support .P7B formats natively and will reject them. Dealing with manual certificate extraction using OpenSSL command-line tools is tedious, error-prone, and frustrating for users who simply need plain text certificate files.
Drop your file here to view and convert it securely right in your browser. For standard web and server use, convert .P7B to PEM, CER, or CRT formats. If you are deploying to a Microsoft IIS server and already possess the corresponding private key on your machine, you will ultimately need a PFX or P12 file.
Convert.Guru analyzes your P7B file, detects the exact format, and lets you read the text inside.
Users also converted PKCS7, P7S, CER, CRT, CA-BUNDLE, PFX, SPC, PKS, P7M, P7C, PDF, ZIP and PEM files.
If you want to convert P7B file to PEM, PFX, CER, CRT, P12, JKS, HTML, HTM, CSS, JS, PHP or ASP, you can use OpenSSL or similar software from the "Digital Certificate Bundle Storage" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to P7B, try OpenSSL or another comparable tool in the "Digital Certificate Bundle Storage" 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 P7B converter.
