Opening a PUBLIC File
The PUBLIC file type is primarily associated with OpenSSH.
What is a PUBLIC file?
PUBLIC files mostly belong to OpenSSH.
PUBLIC files store public key information used in public key cryptography. They hold a public key that accompanies a private key kept secret.
Usage includes:
- SSH Authentication: OpenSSH generates these files for secure remote login. More details can be found at OpenSSH.
- Digital Signatures: Certain PDF files use this format to embed a public key for digital signature verification.
- RSA Encryption in Java: Some PUBLIC files are produced by Java libraries for RSA public key operations.
FilExt.com note: These files are safe to share since they do not contain secret information. They may be opened in plain text editors or with software that supports cryptographic key handling.
How can I open a PUBLIC file?
You need a suitable software like OpenSSH to open a PUBLIC file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PUBLIC file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PUBLIC file directly in the browser:. Just drag the file onto this browser window and drop it.
