Hash Generator
Generate MD5, SHA-1, SHA-256 and SHA-512 hashes from any text input. All processing happens in your browser — nothing is sent to a server.
Frequently Asked Questions
A cryptographic hash function converts any input into a fixed-length string of characters. The same input always produces the same output, but even a tiny change in input produces a completely different hash. Hashes are one-way — you cannot reverse them to get the original input.
For security-sensitive applications, use SHA-256 or SHA-512. MD5 and SHA-1 are considered cryptographically broken and should not be used for passwords or security. They are still fine for checksums and non-security use cases.
Hash functions are deterministic — the same algorithm applied to the same input always produces the same output. This property makes them useful for verifying file integrity and storing password checksums.
