WOLFYXTEK SECURITY TOOLS
Certificate Decoder.
Decode and inspect X.509 certificates, including identity, validity, cryptographic properties, extensions, and security findings.
Analyze your certificate
Paste one or two PEM-encoded X.509 certificates below.
Each certificate is decoded and presented individually.
Certificate Input
Paste the complete PEM certificate, including its delimiters.
MAX 2 CERTIFICATES
0 certificates detected
Submit public certificates only. Never paste private keys. Certificate metadata may be recorded for operational statistics. No certificate trust validation is performed.
Certificate Inspection Results
Certificate Inspection Report
This tool performs X.509 certificate decoding and metadata inspection only. Supplied issuer/subject matches do not establish certificate chain trust. Cryptographic path validation, revocation checking, and live TLS testing are not performed.
Certificate Identity
Extract the subject, issuer, serial number,
Common Name, and Subject Alternative Names.
Cryptography & Validity
Examine validity dates, public key characteristics,
signature algorithms, fingerprints, and X.509 extensions.
Security Findings
Identify predefined indicators such as expired
certificates, approaching expiration, and weak
cryptographic characteristics.
