Multi-Hash Generator: Calculate Multiple Hashes at Once
The Multi-Hash Generator computes multiple hash digests from text or a dropped file, displaying results side by side. Choose which supported algorithms to run, enter any key or salt, and compare the outputs. Copy individual digests or export the results as JSON. It is useful for checking a value against outputs from several algorithms without sending your input to a server.
The Multi-Hash Generator is a browser-based tool for calculating multiple hash digests from text or a file. Use it as a multi-hash generator when you want to compare outputs from supported algorithms in one place, rather than running each calculation separately. You can toggle algorithms on or off, copy individual digests, and export the results as JSON.
To use the tool, provide text or drop a file, then choose the algorithms and options. You can also enter any key or salt. The supported algorithms include MD5, SHA-1/2/3, Keccak, BLAKE2/3, RIPEMD-160, Whirlpool, SM3, and xxHash. Each selected algorithm produces its own digest, displayed alongside the others for comparison.
Hash algorithms can produce different digests from the same input, so outputs are useful to compare when you need to check a value against possible algorithms. Hashing is different from converting between reversible data formats: a hash digest is not a decoded copy of the original input. Generating several results together can help when you are learning how algorithms behave or investigating which algorithm matches a hash value you were given.
The Multi-Hash Generator runs entirely in your browser. Your input is processed on your device and is not sent to a server; once the page has loaded, the tool works offline. Developers and DevOps engineers can use it to check text or file hashes, compare algorithm outputs, and copy or export results without uploading their input.
Step 1: Paste your text or drop a file into the tool. The input is used to calculate hashes with the selected algorithms.
Step 2: Enter any key or salt you want to use. The available input depends on the options provided by the tool.
Step 3: Choose the algorithms and options to run. Toggle algorithms on or off to control which digest results appear.
Step 4: Review the side-by-side digests, then copy an individual result or export the results as JSON.
Use case: Compare a known hash value with results from multiple algorithms. Seeing the digests side by side can help you identify which algorithm may have produced it.
Use case: Learn how different hash algorithms behave by entering a known text value and comparing their outputs.
Use case: Generate hashes locally when you do not want to hand your input to a third-party page.
Use case: Check a hash value supplied by a colleague or in project documentation by calculating candidate digests from the same input.
Use case: Calculate hashes for a file and copy a digest for use in your development or operations workflow.
Use case: Export a set of hash results as JSON when you need to keep or reuse the generated outputs.
