About Hash Generator
Generate digests and supported keyed/password-derived results from text.
Choose the algorithm, enter text and supply the additional key, salt or cost parameters when that mode requires them.
Copy a digest to compare known text inputs; keep password-derived values and their parameters together when reviewing a test.
The calculation or rendering runs in this browser tab. Copy, download and share actions make the chosen output available outside this tab.
Worked example
- Input / settings
- abc; SHA-256
- Action
- Generate
- Result
- ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
Scope and limits
- Output belongs to the current input and settings. Invalid cost/length parameters are rejected. MD5 and SHA-1 are legacy options with known collision weaknesses.
Frequently asked questions
- Can a hash be decoded?
- A digest is not reversible encoding. Matching a digest does not prove authenticity unless the surrounding keyed or signature protocol provides that guarantee.
