Fingerprint Reference
1. SHA-256 Thumbprints
The modern cryptographic standard for certificate pinning, SSL verification, and certificate transparency logging.
2. SHA-1 & MD5 Legacy Use
While SHA-1 and MD5 are deprecated for cryptographic signatures due to collision vulnerabilities, their thumbprints are occasionally referenced for legacy software identification.

Frequently Asked Questions (FAQ)
Thumbprints act as unique cryptographic identifiers for X.509 certificates, commonly utilized in SSL pinning configurations, mobile application trust stores, and system auditing.
Yes. Public certificates contain non-sensitive public key data. All calculations run locally inside your browser memory.
Standard hex-byte separation (using colons every two characters) improves human readability when comparing thumbprints across systems and administrative tools.
