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?
Is this for password hashing?
No. Use a slow password KDF (bcrypt/Argon2) for passwords. This tool is for message digests and checksums.
Which algorithms are supported?
md5, sha1, sha256, sha384, sha512, sha3-256, sha3-512. Prefer SHA-256 or stronger for integrity checks.
What are the key features of Hash Generator?
Legacy warnings
Flags MD5 and SHA-1 for security-sensitive contexts.
Multi-algorithm one page
Avoids thin separate MD5/SHA tool URLs.
How do you use Hash Generator?
Copy the hex digest
Compare against a known good hash or store beside an artifact.
Paste text and pick algorithm
Default SHA-256 for general integrity checks.
HMAC and bcrypt next
Phase 2 adds HMAC and bcrypt tools for keyed MACs and password hashes — keep this page for plain digests.
