Hash Generator (SHA-256 / SHA-384 / SHA-512)
Generate hexadecimal SHA-256, SHA-384, or SHA-512 hash digests from any text input using your browser's Web Crypto API (SubtleCrypto.digest). Commonly used for verifying file integrity, checking data consistency, and understanding cryptographic hashing. No data is sent to any server.
FAQ
Frequently Asked Questions
- Is my data sent to a server?
- No. Hashing uses the SubtleCrypto API built into your browser. Your input never leaves your device.
- Which hash algorithms are supported?
- This tool supports SHA-256 (256-bit), SHA-384 (384-bit), and SHA-512 (512-bit) hash functions using the browser Web Crypto API.
- Can I reverse a hash to get the original text?
- No. SHA-256 and SHA-512 are one-way functions. A hash cannot be reversed to recover its original input.
- Does the same input always produce the same hash?
- Yes. SHA hashes are deterministic — the same input always produces the same output. This is how hash-based integrity verification works.
