Hash Generator
Compute SHA-1, SHA-256, SHA-384, and SHA-512 hashes of any text.
Generate a cryptographic hash of any text using the Web Crypto API. Choose SHA-1, SHA-256, SHA-384, or SHA-512. Computed locally, nothing is uploaded.

Computed locally with the Web Crypto API. Note: SHA-1 is not collision-resistant and should not be used for security.
Formula & methodology
Hashes are computed with SubtleCrypto.digest over the UTF-8 bytes of the input.
Frequently asked questions
Is SHA-1 safe?
SHA-1 is deprecated for security uses because collisions are feasible. Prefer SHA-256 or higher.
Can I hash a file?
This tool hashes text. File hashing may be added later.
