Hash Generator FAQ
What is a hash function? ＋
A hash function converts input text into a fixed-length string of characters. It is designed to be irreversible and is commonly used to verify data integrity.
Can I decrypt a hash? ＋
No. Hashing is one-way. You cannot retrieve the original text from its hash.
Which algorithms are supported here? ＋
Currently, the tool supports SHA-256 (recommended) and SHA-1 (legacy). All calculations happen instantly in your browser.
Is SHA-1 secure? ＋
No. SHA-1 is outdated and vulnerable to collision attacks. Use SHA-256 for security-critical purposes.
Is my input text sent to servers? ＋
No. Hashing runs fully client-side in your browser. Nothing is uploaded or stored.
