Choosing an algorithm, and when the broken ones are still fine
This tool computes MD5, SHA-1, SHA-256, SHA-384 and SHA-512. Two of those are cryptographically broken, and they are still here on purpose — because "broken" answers a narrower question than most people assume.
What broken actually means
MD5 and SHA-1 are broken against collision attacks: an attacker can construct two different inputs that hash to the same value. This was demonstrated for MD5 in 2004 and for SHA-1 in 2017. That defeats them completely for signatures, certificates and anything where an adversary chooses the content.
They are not broken against preimage attacks, meaning nobody can take a hash you produced and work backwards to a file matching it. So for the everyday case — you downloaded an ISO, the project published an MD5, you want to know whether the transfer corrupted the file — MD5 still answers that question correctly. It is checking against accident, not against an adversary.
The practical rule: if an attacker could have chosen the input, use SHA-256. If you are comparing against a checksum published by someone you trust over a channel you trust, whichever algorithm they published is the one you need.
Do not use any of these for passwords
All five are designed to be fast, and speed is exactly wrong for password storage — it means an attacker with a stolen database can try billions of guesses per second. Password hashing needs a deliberately slow, memory-hard function: Argon2id, scrypt, or bcrypt. A SHA-256 of a password, salted or not, is not password hashing.
Hashing here happens in your browser through the Web Crypto API, so the file or text you hash is never uploaded.
