Use Hash Generator three ways
The free Hash Generator on this page works in your browser. The same workflow is available via REST API for apps and via MCP for Cursor, Claude, and other agents — one API key, one plan, one quota. This tool is part of the security-apis module under Security Tools.

What is Hash Generator?
Compute MD5, SHA-1, SHA-256/384/512, or SHA-3 digests of text in one place. ToolYour Hash Generator returns hex output and warns when you pick legacy MD5/SHA-1 for security-sensitive hashing. Digests are not password storage — use bcrypt/Argon2 (Phase 2) for passwords. REST/MCP POST with { "text", "algorithm" }.
What are common questions about Hash Generator?
Which algorithms are supported?
md5, sha1, sha256, sha384, sha512, sha3-256, sha3-512. Prefer SHA-256 or stronger for integrity checks.
Is this for password hashing?
No. Use a slow password KDF (bcrypt/Argon2) for passwords. This tool is for message digests and checksums.
What are the key features of Hash Generator?
Multi-algorithm one page
Legacy warnings
How do you use Hash Generator?
Paste text and pick algorithm
Copy the hex digest
HMAC and bcrypt next
Phase 2 adds HMAC and bcrypt tools for keyed MACs and password hashes — keep this page for plain digests.
