Tools
Encode, decode, and utility tools for threat intelligence and daily security operations.
Encoding & decoding
Base64 encoder/decoder
Encode or decode text in Base64 (standard or URL-safe). Useful for payloads, tokens, or data inspection.
URL encode/decoder
Percent-encode or decode strings (space as + or %20). Supports multiple decode passes for nested encoding.
JWT Decoder
Decode a JWT and display header and payload in readable form. Signature is not verified (inspection only).
Network & lookup
WHOIS + DNS Lookup
Query WHOIS for a domain: registrar, creation/expiry dates, name servers. Includes DNS records (A, AAAA, MX, TXT, etc.). Domain only (no IP).
CIDR Calculator
Compute subnet details from an IP and mask: network address, broadcast, netmask, wildcard, first/last usable IP, and host count.
Certificate parser (X.509)
Parse an X.509 certificate (PEM or DER) and display subject, issuer, validity, SAN, key usage, and public key info. Same logic as ittools_cli x509.
Email & URLs
Email headers extractor
Parse raw email headers or .eml files: From/To, SPF/DKIM/DMARC results, Received hop chain, X-Headers. No signature verification.
URL Deobfuscator
Decode percent-encoded URLs, detect redirect parameters, and list tracking (UTM, gclid, fbclid, etc.) for safer link analysis.
Threat intelligence & IOC
IOC Extractor
Extract indicators of compromise from pasted text or uploaded files: emails, domains, IPv4/IPv6, URLs, MD5/SHA1/SHA256 hashes.
Hash type
Determine the type of a hash (MD5, SHA-1, SHA-256, SHA-512, etc.) from its length and format. Paste one or more hashes (one per line or comma-separated).
Date & time
Datetime/Timestamp converter
Convert Unix epoch ↔ human-readable date. Show the same instant in UTC, Europe/Paris, America/New_York, and other timezones.
Cron Parser
Parse a 5-field cron expression (minute hour day month weekday), show a human-readable breakdown and the next run times.
Generators
UUID Generator
Generate UUIDs: v4 (random) or v1 (time-based). Useful for unique IDs, tokens, or test data.
Password Generator
Generate cryptographically secure passwords with configurable length and character sets (upper, lower, digits, symbols). Option to exclude ambiguous characters.
Data & logs
JSON Formatter
Format (pretty-print) or minify JSON. Validates and re-indents or compacts your JSON for readability or size.
Log Prettify
Prettify logs (same as ittools_cli): auto-detect JSONL/JSON/plain, pretty-print with optional stats (most seen fields, value distribution by level/status/method, level counts for plain).
