Frequently Asked Questions
What is the difference between MD5 and SHA-256? ▼
MD5 produces a 128-bit hash and is fast but cryptographically broken - it should not be used for security purposes. SHA-256 produces a 256-bit hash and is the current standard for secure hashing, used in TLS certificates, code signing, and blockchain.
What are hashes used for? ▼
Hashes verify file integrity (checksums), store passwords securely, create digital signatures, and detect data tampering. A hash is a fixed-size fingerprint of any input - even a single character change produces a completely different hash.
Is my data sent to a server? ▼
No. All hashing runs in your browser using the Web Crypto API (for SHA family) and pure JavaScript (for MD5). Your input never leaves your device.
