Terms of Service

By using plato·cert, you agree to these terms.

The tool is free

This is a free web utility. There is no account, no subscription, no payment. You may use it for personal, commercial, educational, or any lawful purpose.

No warranty

The tool is provided "as is" without warranty of any kind. Certificate parsing uses standard ASN.1/DER decoding, but always verify certificate information through official channels (your CA portal, openssl, or your operating system's certificate manager) before making security decisions.

• OID-to-name mappings cover common extensions; uncommon extensions display raw OID notation.
• Fingerprints are computed via the browser's SubtleCrypto API; always cross-verify critical fingerprints using openssl on a trusted machine.
• This tool is not a substitute for a professional TLS audit or security assessment.

Security reminder

Never paste private keys into any online tool. This tool is designed for certificates (public data), not private keys. While this tool processes data locally, the habit of pasting private keys into web forms is dangerous.

You are responsible for the actions you take based on the tool's output. We are not liable for any security failures, misconfigurations, or damages resulting from your use of this tool.
