Hash Generator
Generate SHA-256, SHA-1 and SHA-512 hashes of text online, free. Computed with Web Crypto in your browser, nothing is uploaded.
Hashes are computed in your browser with the Web Crypto API. (MD5 is intentionally omitted — it's insecure and not supported by Web Crypto.)
How to use Hash Generator
- Enter or paste the text you want to hash.
- Choose an algorithm (SHA-256, SHA-1 or SHA-512).
- Copy the resulting hash, it updates as you type.
About Hash Generator
Hash Generator is a free Becoderr tool. It needs no sign-up, runs fast and privately, and works right in your browser for most tasks. For the few server-based tools, your files are processed in memory and discarded immediately after the operation.
Frequently asked questions
What is a hash used for?
Hashes create a fixed-length fingerprint of data, useful for checksums, verifying file integrity and storing password digests.
Can a hash be reversed?
No, cryptographic hashes are one-way. You cannot recover the original text from the hash.
Is this tool free to use?
Yes. Every tool on Becoderr is completely free with no sign-up required. Signed-in users get higher file-size limits.
Are my files safe?
Yes. Browser-based tools process files entirely on your device; nothing is uploaded. Server-based tools process files in memory and discard them immediately after the operation.
Is there a file size limit?
Server-based tools accept up to 5 MB for anonymous users and 50 MB when signed in. Browser-based tools are limited only by your device.
