Tools / Hash generator

Hash & checksum generator

Calculate a SHA-2 digest for text or a file without uploading it. Hashes can help compare data; a matching hash alone does not prove a file is safe or authentic.

Algorithm

Text input

Or select a file (up to 25 MB). Choosing a file will clear the text input.

File input

Digest (hex)

About these hashes

SHA-256, SHA-384 and SHA-512 are provided by the browser's Web Crypto API.
Input stays on your device. File hashing is limited to 25 MB to avoid excessive memory use.
These are cryptographic hashes, not password hashing functions. Do not use them to store passwords.
