openssl — Cryptographic Toolkit
Category
TLS & Certificate Operations
License
Apache 2.0
Source
https://github.com/openssl/openssl
Purpose
TLS/SSL testing, certificate inspection, cryptographic operations, connection diagnostics.
Use Cases
- Verify TLS configurations on peer agent connections
- Inspect peer certificates for validity and expiry
- Test cipher suites offered by a service
- Generate CSRs for certificate rotation
- Check certificate chain integrity
- Verify certificate expiry dates
Examples
# Connect to a peer and show certificates
openssl s_client -connect <host>:27027 -showcerts </dev/null
# Inspect a certificate file
openssl x509 -in cert.pem -text -noout
# Check if certificate expires within 24 hours
openssl x509 -in cert.pem -checkend 86400
# Verify a certificate chain
openssl verify -CAfile ca.pem cert.pem
# Show certificate fingerprint
openssl x509 -in cert.pem -fingerprint -sha256 -noout
# Test TLS connection with specific protocol
openssl s_client -connect <host>:27027 -tls1_3 </dev/null
Safety Notes
- Inspection and verification commands are read-only and safe.
- Certificate generation and key operations should follow §6 configuration for TLS paths.
- Never output private keys to logs or reports.
