Hash Generator

No. Hashing is one-way — you cannot recover the input from the hash. Encryption is reversible with a key. Use the Text Encryptor when you need to decrypt later. Hash functions are deterministic, so the same input always produces the same hash output, making them useful for checksums and password verification. Because hashing is irreversible, it's the industry standard for storing passwords securely — a stolen password hash cannot be converted back to a plaintext password. Encryption, by contrast, scrambles data so only someone with the decryption key can read it again, making it suitable for protecting data you need to retrieve later.

No. Everything runs locally in your browser using standard web APIs — your text, files and inputs are never uploaded to a server, so the tool works even offline once the page has loaded.

Prefer SHA-256 or stronger for integrity checks. SHA-1 is included for legacy compatibility but is no longer considered collision-resistant. For password hashing, don't use any of these algorithms directly — use bcrypt, Argon2, or PBKDF2 instead, which include built-in salting and slowness to resist brute-force attacks. SHA-256 produces a 64-character hash ideal for file checksums, data integrity verification, and blockchain applications. SHA-512 is even stronger and often used in highly secure systems, though SHA-256 is sufficient for nearly all practical purposes.
