Robust, commercial-grade, full-featured toolkit for general-purpose cryptography, TLS/SSL connection inspection, and X.509 certificate administration.
A standard CRYPTOGRAPHY utility used across offensive reconnaissance, packet forensics, and defensive system administration.
Direct visibility into network interfaces, protocol frames, access controls, or filesystem structures without graphical overhead.
During live system triage, initial reconnaissance, forensic capture inspection, or baseline configuration auditing.
# Standard on Linux and macOS
openssl version
# Debian / Ubuntu
sudo apt install opensslCryptographic operations & TLS probes:
- Inspect TLS handshake and server certificate: openssl s_client -connect example.com:443 -tls1_3
- Inspect X.509 certificate details: openssl x509 -in cert.crt -text -noout
- Generate 2048-bit RSA private key: openssl genrsa -out private.key 2048
- Calculate SHA-256 digest of file: openssl dgst -sha256 file.bin
