A dictionary-based MD5 reverse lookup service. Users can convert a string to its MD5 hash or submit a hash to look it up in a database of several million entries. The site explains what MD5 is and notes that MD5 hashes are theoretically impossible to reverse directly. It also lists recent successful reverses and links to related cryptography resources.

A cloud GPU password recovery and credential auditing service for data the user owns or is authorized to test. It supports Office, ZIP, PDF, Wi-Fi captures, NTLM and AD hashes, with a free Basic Search and optional paid custom GPU jobs and unlocks. An authenticated REST API and MCP tools are documented. Uploaded files are deleted after hash extraction.
A hash lookup service where users submit hashes and search a database of already-cracked hashes for corresponding plaintext. It supports hash types including MD5, SHA-1, SHA-256, SHA-512, MySQL, NTLM, Bcrypt and Wordpress. The database has been built since August 2007.
CrackStation is an online password hash cracking service that uses pre-computed lookup tables to recover passwords from unsalted hashes. It supports hashes including MD5, SHA1, SHA2 and WPA, accepts up to 20 non-salted hashes, and offers a downloadable wordlist and a command-line tool for local index generation and lookup.
Community hash-recovery platform for searching, submitting, and discussing password hash challenges.
An online tool that calculates checksums of ASCII or Unicode text and of files up to 5MB, using a list of hash algorithms including MD5, SHA1, SHA256 and SHA512. It states that checksums are commonly used to verify data integrity, such as confirming a downloaded file is error-free.
Leak Lookup is a data breach search engine for searching database leaks and dumps. It offers username, email and IP address lookups across thousands of breaches to help track credentials compromised in the wild. A hash API provides hash-cracking capabilities and an API key is required to make requests.
Hash search database for looking up password hashes and contributed recovery results.
A site for searching MD5 hashes in a database and generating MD5 digests, with hashing and encoding tools. It notes that hashing is one-way and that matches are found by comparing digests or looking up a hash-to-plaintext database.
Online hashing tool for generating and checking MD5, SHA, and other common hash values.
OSINT.SH is a collection of information gathering tools. It lists tools for finding public cloud buckets, subdomains, DNS history, reverse IP lookups, technology detection, certificate searches, DNS lookups, reverse Google Analytics and AdSense IDs, WHOIS history, reverse WHOIS, reverse domain searches, OCR text extraction, MD5 hash guessing, SSL checking, IP geolocation, and reverse MX and name server records.
Threat intelligence search service for checking IPs, domains, hashes, and security indicators.
Threat intelligence search platform for malware indicators, IPs, domains, URLs, and hashes.
Security lookup platform for scanning files, hashes, URLs, IPs, and domains against threat data.
Browser extension for searching IPs, domains, hashes, URLs, and indicators across threat intelligence services.
Python tool that identifies hashes, emails, IPs, URLs, and other strings found in text or files.
Threat intelligence search engine for domains, IPs, hashes, malware, and related indicators.
Intelligence X provides a collection of free open source intelligence (OSINT) and forensic tools for investigative use. The tools support lookups for emails, domains, IP addresses, Bitcoin addresses, images, usernames, people, phone numbers, locations, files, VINs, and hashes, alongside social media intelligence tools for Facebook, Twitter, LinkedIn, Telegram, and YouTube, plus AI-powered search features. All third-party lookup services open in pop-up tabs, and the provider disclaims responsibility for third-party service results.
Universal Installer is an Android app for installing and managing APK packages on phones, Android TV and Wear OS. It supports split APK bundles and manual splits, extracts OBB game data, and offers silent install via Shizuku, root or the system installer. It also provides VirusTotal hash lookups before install, local sharing to TVs, and an app manager.
Security scanning service for checking files, URLs, domains, and hashes across many detection engines.
