About IP Lookup
What this tool does
Privacy and security tools generate cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512), check password strength, look up IP addresses and WHOIS records, validate emails, and generate privacy policies and legal documents.
Why use this tool
Verifying file integrity, checking whether a password meets security requirements, and generating legal boilerplate are routine tasks for developers and site owners. Doing them locally keeps sensitive data off third-party servers.
How it works
Hash generation uses the Web Crypto API (SubtleCrypto.digest) for standard algorithms. Password strength analysis evaluates entropy, checks against common password lists, and estimates crack time. IP and WHOIS lookups query public databases.
Pro tip
SHA-256 is the go-to hash for file integrity checks. MD5 and SHA-1 are still seen in legacy systems but should not be used for security purposes, as collision attacks against them are practical.
