SHA algorithm reference
| Algorithm | Digest size | HEX length | Typical use |
|---|---|---|---|
| SHA-1 | 160 bits | 40 chars | Legacy fingerprints only; avoid for new security-sensitive work |
| SHA-256 | 256 bits | 64 chars | Checksums, integrity checks, package verification, API signatures |
| SHA-384 | 384 bits | 96 chars | Longer digest option for modern systems |
| SHA-512 | 512 bits | 128 chars | Long digests, release checksums, high-margin integrity fingerprints |
Hashing notes
Local processingText and files are hashed in the browser with Web Crypto. File content is not uploaded to this server.
Deterministic outputThe same bytes with the same algorithm always produce the same digest.
Encoding mattersText input is encoded as UTF-8 before hashing. File input hashes the raw file bytes.
Not reversibleSHA hashes are fingerprints. They cannot be decoded back to the original text or file.
FAQ
Should I use SHA-1?
Use SHA-1 only when you must match an old system or published legacy checksum. For new integrity checks, SHA-256 is the practical default.
Can this hash large files?
The browser reads the selected file into memory before hashing. It is fine for common downloads and documents, but very large files may be limited by available device memory.
Can I verify a published checksum?
Yes. Select the same algorithm, hash the text or file, then paste the published HEX or Base64 checksum into the compare field.
