Hash Generator (All)

How to use Hash Generator (All)

1. Paste the text you want to fingerprint.
2. All digests compute at once as you type.
3. Copy the one you need, or match an unknown checksum by its length.
4. Input is encoded as UTF-8 before hashing, which is what other tools and libraries default to.
5. SHA algorithms use the browser’s Web Crypto implementation; MD5 is computed in JavaScript since Web Crypto deliberately omits it.
6. Nothing is uploaded — the text stays in the page.

Identifying a hash by its length

Hex digests have a fixed width per algorithm, which is the quickest way to identify an unlabelled checksum. 32 characters is MD5. 40 is SHA-1. 56 is SHA-224, 64 is SHA-256, 96 is SHA-384 and 128 is SHA-512. If it is 60 characters and starts with $2a$ or $2b$ it is bcrypt, which is a password hash with its cost and salt embedded and cannot be reproduced here. Anything ending in = is probably Base64 rather than hex, so decode it first.

Which of these you should actually use

SHA-256 for anything new. SHA-512 where you want a larger margin, and it is often faster on 64-bit hardware. SHA-1 only to verify something legacy — it has practical collisions and browsers and certificate authorities dropped it years ago. MD5 only for non-adversarial checksums: cache keys, deduplication, spotting accidental corruption. For passwords, none of these: they are all far too fast, and you want Argon2id, scrypt or bcrypt.

Comparing two digests properly

Compare the whole string, case-insensitively — hex is conventionally lowercase but some tools print uppercase, and both are the same value. A digest matching on the first eight characters proves nothing. Also check you are hashing the same thing: a published checksum covers a file’s raw bytes, while this tool hashes the text you paste, and a trailing newline is enough to change every digit of the result.
