Frequently Asked Questions
Is hashing encryption?
No. A cryptographic hash is designed to be one-way and is not decrypted like ciphertext.
Which algorithms are supported?
The browser Web Crypto API commonly provides SHA-1, SHA-256, SHA-384 and SHA-512.
Is my input uploaded?
No. The digest is calculated locally.
Can I hash files?
The current tool focuses on text; file hashing can be added without a server by reading the file locally.
