Our History
CrysM.net started as a simple MD5 hash lookup tool, growing from a personal project into a comprehensive cryptographic resource. Over the years, we've expanded our database to include multiple hash algorithms and built tools that serve thousands of users daily.
We've operated under various subdomains to provide region-specific services, including us.md5.crysm.net and nz.md5.crysm.net, all now unified under our main domain for a better user experience.
Responsible Use
We're committed to providing our tools for legitimate purposes only. Our services are designed for file verification, security research, password recovery for owned accounts, and educational purposes. We actively monitor for and prevent misuse of our platform.
