Hash Generator FAQ
What is a hash used for?
A hash is a fixed-length fingerprint of data. It is used to verify that a file or message has not changed, to store passwords safely (with SHA-256 and stronger), and to create checksums for downloads.
Which hash should I use?
For anything security related, use SHA-256 or SHA-512, which are strong and modern. MD5 and SHA-1 are fine for quick checksums but are considered weak for security, so avoid them for passwords.
Is MD5 safe to use?
MD5 is fast and fine for non-security checksums, like verifying a download did not corrupt. It should not be used for passwords or security, because it can be broken. Use SHA-256 instead for those.
Is my data safe?
Yes. Hashing runs entirely in your browser on your own device. Your text is never sent to any server, so even sensitive input stays private.
Do I need to sign up?
No. The hash generator is free with no account and no limits.
