Hash Generator
Generate SHA-1, SHA-256, or SHA-512 hashes from text or files. Output as hex or Base64. All hashing runs locally.

Output format
A cryptographic hash function takes an input (text or binary data) and produces a fixed-length output called a hash or digest. The same input always produces the same hash, but even a tiny change in the input produces a completely different hash. Hash functions are one-way — you cannot reverse a hash to get the original input. They are widely used in software development for verifying data integrity, storing passwords securely, generating checksums, and many security protocols. Common algorithms include SHA-256 (most widely used), SHA-512 (stronger), and SHA-1 (legacy, now considered weak).
