SHA-256 Hash & Verify
Hash text or files with SHA-256 and verify against a published 64-character checksum, computed locally with case-insensitive comparison.

SHA-256 Hash & Verify vs SHA-512 Hash & Verify — What's the Difference?
The short answer: Both are collision-resistant SHA-2 tools that hash text or files up to 256 MiB entirely in your browser and compare against a known digest case-insensitively. SHA-256 produces the 64-character digest the world publishes as standard checksums. SHA-512 produces a 128-character digest with a larger internal state, computed in chunked Worker runs — pick it when a policy or a paranoid threat model asks for more margin.
Comparison of SHA-256 Hash & Verify and SHA-512 Hash & Verify
| SHA-256 Hash & Verify | SHA-512 Hash & Verify | |
|---|---|---|
| Purpose | Hash text or files with SHA-256 and verify against a published 64-character checksum, computed locally with case-insensitive comparison. | Hash text or files with SHA-512 and verify against a known 128-character digest, computed locally in chunked Worker runs. |
| Input | Text or a file up to 256 MiB, hashed in raw-byte chunks | Text or a file up to 256 MiB, hashed in chunked Worker runs |
| Output | A 64-character (256-bit) digest, compared case-insensitively | A 128-character (512-bit) digest, compared case-insensitively |
| Typical use | Verifying downloads against published checksums — the standard choice | Integrity checks where policy or threat model demands the larger digest |
Key differences
SHA-256 Hash & Verify vs SHA-512 Hash & Verify
What it does
Depends on the taskBoth hash and verify; the difference is digest size — 64 characters versus 128 — not workflow.
Input
Depends on the taskBoth accept text or files up to 256 MiB, processed in raw-byte chunks locally.
Output
Depends on the taskSHA-256 yields 64 hex characters; SHA-512 yields 128, with both comparisons ignoring letter case.
Best for
Depends on the taskPublished checksums and everyday integrity work point to SHA-256; mandated maximum-margin policies point to SHA-512.

Frequently asked questions
What's the difference between SHA-256 Hash & Verify and SHA-512 Hash & Verify?
Both belong to the SHA-2 family and are computed entirely in your browser, even for files up to 256 MiB. SHA-256 outputs 64 hex characters and is the digest you will find on release pages; SHA-512 outputs 128 characters, runs in chunked Worker passes, and offers a larger security margin at the cost of a longer string to compare.
Can I use SHA-256 Hash & Verify and SHA-512 Hash & Verify together?
Follow the digest the publisher provides — checksum files name their algorithm, and each tool only verifies its own. If a download page lists SHA-256, use the SHA-256 tool; reach for SHA-512 when your own policy, not the publisher, requires it.
