What is a SHA hash?
SHA-256 turns any input, from one word to a whole document, into a fixed 64-character hex digest; change a single letter and the digest changes completely. This generator computes SHA-1, SHA-256, SHA-384 and SHA-512 via the native Web Crypto API, and its digests match what OpenSSL or Python’s hashlib produce for the same text.
How to use the Hash Generator
- 1 Enter the text you want to fingerprint.
- 2 Pick an algorithm; SHA-256 is the safe default for new work.
- 3 Read the hex digest as it recomputes on every keystroke.
- 4 Copy the digest for your checksum, cache key or comparison.
What you can use it for
- Verifying data integrity with checksums.
- Generating fingerprints for cache keys.
- Comparing values without storing the original.
- Learning how cryptographic hashing works.
Frequently asked questions
Which hash algorithms are supported?
SHA-1, SHA-256, SHA-384 and SHA-512. Output lengths are 40, 64, 96 and 128 hex characters respectively, which is a quick way to tell digests apart at a glance.
Is MD5 available?
No. The Web Crypto API deliberately omits MD5 because collisions can be produced cheaply. If a legacy system demands MD5, treat that as a migration flag and use SHA-256 everywhere else.
Can I safely hash secrets or API keys?
Hashing runs on your device through the Web Crypto API; no network request carries the input. Even so, prefer test values over production secrets as general hygiene.
Can I hash files?
Text only for now. Paste file contents if they are textual; for binaries, reach for a command-line tool like sha256sum until file support lands.
