Extract text from CA files
To convert your CA file to another format, you need OpenSSL or other System software.
To convert other file formats to the "Security Certificate" file type, you need software like OpenSSL or a similar tool.
A .CA file represents a collision of several distinct formats, predominantly serving as a Certificate Authority bundle or trust store. In server environments, these files contain a list of trusted root certificates (formatted as X.509 text) required by software like OpenSSL to validate secure SSL/TLS connections. Users typically encounter friction here because standard certificate managers on Windows or macOS often demand CRT, CER, or PEM extensions, leaving the .CA file unrecognized and "double-click dead" despite just being text data.
Another frequent variation is the iOS analytics crash report. These are technically JSON text files that have been renamed or saved with a .CA extension (often found in raw device logs), detailing app failures. Users need to convert these to standard JSON or TXT to make the stack traces readable in text editors like Notepad++ or Sublime Text.
Less commonly, you might face a binary DataPhysics measurement file or a legacy Telnet cache. For the certificate and log variants, the file is essentially text locked in an obscure container. The pragmatic solution for readability and compatibility is converting these files to TXT (for analysis), PEM (for server installation), or PDF (for archiving crash reports).
Convert.Guru analyzes your CA file, detects the exact format, and lets you read the text inside.
Users also converted SYNCED, CA1, DWG, PDF, ZIP, DER, PEM, P7B and US files.
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 CA converter.
