Extract text from P10 files
To convert your P10 file to another format, you need OpenSSL or other System software.
To convert other file formats to the "PKCS #10 CSR" file type, you need software like OpenSSL or a similar tool.
A .P10 file acts as a digital application form, technically known as a PKCS #10 Certificate Signing Request (CSR). System administrators generate this file to request a digital identity certificate from a Certificate Authority (CA) like DigiCert or Let's Encrypt. Internally, it contains your public key and organization details (Subject), usually encoded in a Base64 ASCII block flanked by "BEGIN CERTIFICATE REQUEST" headers.
A common problem with .P10 files is confusion about their utility: a .P10 is not a functioning certificate. You cannot install it on a web server to enable HTTPS; it is merely the question waiting for an answer (the final CRT or CER file). Additionally, because the data is encoded in ASN.1 structure, the file appears as a gibberish block of random characters in standard text editors. Users often struggle to verify if the "Common Name" or "Country" fields are correct without using complex command-line tools like OpenSSL.
For verification, convert the .P10 to TXT to read the decoded subject lines. If you are moving between server types (e.g., Apache to Windows), you may need to convert the encoding between PEM (Base64) and DER (Binary). To archive the request parameters for compliance, a conversion to PDF allows for human-readable storage.
Convert.Guru analyzes your P10 file, detects the exact format, and lets you read the text inside.
Users also converted OPENPGP_SIGNATURE, REQ, 89Q, CSR, PEM and P12 files.
If you want to convert P10 file to CSR, PEM, P12, TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART or DOWNLOAD, you can use OpenSSL or similar software from the "Digital Certificate Request" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to P10, try OpenSSL or another comparable tool in the "Digital Certificate Request" 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 P10 converter.
