IP Address Lookup
Look up any IP — location, ISP, risk score and reverse DNS.
Cryptographic Password Generation, TLS Inspection & Network Diagnostics
Online security starts with high-entropy credentials and properly configured transport encryption. PursTech's Security Tools give everyday users, system administrators, and web developers instant access to cryptographic password generation, live TLS/SSL certificate grading, and IP network intelligence without requiring command-line utilities like OpenSSL or dig.
Our Password Generator never uses predictable Math.random() calls; instead, it draws entropy directly from your operating system's CSPRNG via window.crypto.getRandomValues(), calculating real-time bit entropy and estimated brute-force resistance times across character sets or memorable multi-word passphrases. Everything happens locally in your browser memory—generated passwords never touch the network.
For server and domain diagnostics, our SSL Certificate Checker performs a live TLS handshake against port 443 to inspect certificate validity windows, key bit-lengths, TLS 1.2/1.3 protocol negotiation, cipher suites, and Subject Alternative Names (grading configurations from A+ to F), while our IP Address Lookup surfaces geolocation, ASN/ISP ownership, timezone, and network metadata.
