Best use
Use it for a focused SHA-1 / SHA-256 / SHA-512 Digest Tool task when a quick browser workbench is appropriate.
SHA-1 / SHA-256 / SHA-512 Digest Tool
Generate deterministic SHA-1, SHA-256, and SHA-512 hexadecimal digests with Web Crypto for checksums and compatibility tests.
Digest behavior and algorithm choice
The same UTF-8 input produces the same digest. A one-character change produces a different value. A digest does not encrypt the input and cannot prove who created it unless it is used inside an authenticated construction.
- SHA-256 / SHA-512: suitable for modern non-secret digest and checksum workflows.
- SHA-1: retained for compatibility with older identifiers and fixtures, not for collision-resistant signatures.
- Passwords: use a dedicated password-hashing function with salt and cost controls, not a fast SHA digest.
Input contract
The workbench hashes UTF-8 bytes and returns lowercase hexadecimal output. Preserve line endings, normalization, and trailing spaces when comparing with another implementation; visually identical text can have different byte sequences.
Usage boundaries and result checks
SHA-1 / SHA-256 / SHA-512 Digest Tool is for this task: Generate deterministic SHA hexadecimal digests with Web Crypto for checksums and compatibility tests. It runs in the browser; start with a short, non-sensitive sample and confirm the behavior before processing more data.
Input
non-sensitive text or test data
Output
one or more digests, checksums, or compatibility values
Before reuse
For SHA-1 / SHA-256 / SHA-512 Digest Tool: A digest is not encryption. Use an appropriate modern construction for passwords, authenticity, or signatures. See the test method.
