MD5 Hash & Verify vs SHA-256 Hash & Verify — What's the Difference?

The short answer: MD5 Hash & Verify / SHA-256 Hash & Verify: Inputs and controls / Visible result and export. MD5 · Hash text or files up to 256 MiB locally, verify a digest and demonstrate bounded ASCII candidates. Compare downloads against trusted reference checksums. Hashes are one-way. This checks only a chosen ASCII candidate space; finding a match does not recover every possible original. Limits: length 1–6, at most 100,000 attempts and five seconds. No dictionaries, uploads or remote lookup. MD5 and SHA-1 are legacy algorithms and are unsuitable for modern security uses. SHA-256 · Hash text or files up to 256 MiB locally, verify a digest and demonstrate bounded ASCII candidates. Compare downloads against trusted reference checksums. Hashes are one-way. This checks only a chosen ASCII candidate space; finding a match does not recover every possible original. Limits: length 1–6, at most 100,000 attempts and five seconds. No dictionaries, uploads or remote lookup. Choose by the task and review the current limits before exporting.

OutputMD5 Hash & Verify: Clear empties the input, the expected digest, and the result in one step, and the status returns to Ready. Nothing is kept between runs, so a list of identifiers can be checked one after another without leftovers.SHA-256 Hash & Verify: Clear empties the input, the expected digest, and the result in one step, and the status returns to Ready.

Frequently asked questions

What's the difference between MD5 Hash & Verify and SHA-256 Hash & Verify?
Inputs and controls. MD5 Hash & Verify: Stay on the Hash tab and press Create digest. The local engine computes the digest and shows it in the read-only MD5 digest field as 32 lowercase hexadecimal characters, the same spelling used by release pages and checksum files. Hashes are one-way. This checks only a chosen ASCII candidate space; finding a match does not recover every possible original. Limits: length 1–6, at most 100,000 attempts and five seconds. No dictionaries, uploads or remote lookup. SHA-256 Hash & Verify: Stay on the Hash tab and press Create digest. The local engine computes the digest and shows it in the read-only SHA-256 digest field as 64 lowercase hexadecimal characters, the same spelling used by release pages and checksum files. Hashes are one-way. This checks only a chosen ASCII candidate space; finding a match does not recover every possible original. Limits: length 1–6, at most 100,000 attempts and five seconds. No dictionaries, uploads or remote lookup.
Can I use MD5 Hash & Verify and SHA-256 Hash & Verify together?
Visible result and export. MD5 Hash & Verify: Clear empties the input, the expected digest, and the result in one step, and the status returns to Ready. Nothing is kept between runs, so a list of identifiers can be checked one after another without leftovers. SHA-256 Hash & Verify: Clear empties the input, the expected digest, and the result in one step, and the status returns to Ready. Nothing is kept between runs, so a list of identifiers can be checked one after another without leftovers. Use the first tool for this task; use the second for its separate result.
