Defensive security, password entropy, SSL inspectors, DNS/SPF/DMARC checkers, and URL security analyzers.
Analyze password length, character diversity, entropy bits, and common dictionary weaknesses.
Generate strong, random, secure passwords with customizable length, symbols, numbers, and uppercase/lowercase rules.
Generate highly memorable, multi-word passphrases with custom separators and capitalization.
Upload or drag-and-drop a local file to compute MD5, SHA-1, SHA-256, and SHA-512 hashes client-side.
Calculate text and payload checksums including CRC32, MD5, and SHA family digests.
Inspect an authorized website's HTTP response headers to identify missing security policies like CSP, HSTS, and X-Frame-Options.
Inspect public SSL/TLS certificates for domain issuer, expiration date, SANs, and TLS protocol details.
Query public DNS records (A, AAAA, MX, TXT, NS, CNAME, CAA) to inspect security configurations.
Inspect a domain's Sender Policy Framework (SPF) TXT record and break down its mechanisms.
Analyze a domain's DMARC record to inspect policy enforcement (none, quarantine, reject) and alignment settings.
Lookup public DomainKeys Identified Mail (DKIM) records by domain and selector.
Analyze a URL for HTTPS usage, suspicious encoding, unusual ports, deceptive domain structures, and risk factors.
Display publicly available IPv4/IPv6 address classification, reverse DNS, and basic network info.
Calculate network address, broadcast address, subnet mask, usable host range, and host count from CIDR notation.
Calculate subnet divisions from an IP address and required number of subnets or hosts per subnet.
Search common TCP/UDP port numbers and display their standard assigned services and protocols.
Generate recommended HTTP security header configurations for Apache (.htaccess), Nginx, and PHP applications.
Generate configurable password policy documentation and enforcement standards for organizations.
Generate hardening checklists for PHP sites, Linux servers, Windows, APIs, Databases, WordPress, and Cloud.
Analyze text strings to identify encoding formats including Base64, Hexadecimal, URL Encoding, and HTML entities.
