Hash generator

How to use Processed in your browser

Create a hexadecimal digest of exact UTF-8 text, including spaces and line endings. Empty input is valid.

AlgorithmText size

SHA-256 is the default for checksums. Hashes are not encryption or password storage.

Privacy & draft storage

Tool input and output stay in your browser. Neither is uploaded or saved by the toolkit.

Copy writes the result to your device’s clipboard. Save downloads a file to your device.
Switching tools or returning home keeps drafts in this tab’s memory.
Reloading or leaving the toolkit clears drafts. Nothing is saved to browser storage.

Clearing a tool does not erase a copy already on your clipboard or a file you saved. A dot beside a tool marks an edited draft.

How to use

Hash generator

Enter the exact text to hash, or use empty input if that is your intended message.
Choose an algorithm. SHA-256 is the default.
Compute the digest, then copy or save the hexadecimal result.

Exact text matters

The digest includes all UTF-8 text, spaces and line endings. Even a trailing newline can change the result.

This tool hashes text, not binary files. Input is limited to 500,000 UTF-16 code units.

Hashing is not encryption

A hash is a one-way digest. There is no decrypt operation to recover the original text.

MD5 and SHA-1 are for legacy compatibility, not collision-resistant security uses.
Fast hashes are not suitable for storing passwords. Password storage needs a dedicated scheme.
