PEM Parser

Paste any PEM text (can contain multiple blocks, like certificate chain + public key), auto-identify each block type (certificate, CSR, SPKI public key, PKCS#8 private key, PKCS#1 / SEC1 legacy private key, CRL), show DER byte length, and provide key algorithm, bit length / curve when possible; certificate blocks include subject, issuer, validity, fingerprint digest. Pure browser-side parsing, never uploaded.
