A cryptographic hash is a fixed-length fingerprint of any input. The same input always produces the same hash, but it is computationally infeasible to reverse — you cannot recover the original text from the hash.

Which hash algorithm should I use?

For security-sensitive use cases, use SHA-256 or SHA-512. SHA-1 and MD5 are considered cryptographically broken for security purposes, but are still used for checksums and data integrity verification.

MD5 is not safe for password storage or digital signatures, but is still widely used for file checksums, cache keys, and non-security data fingerprinting because it is fast and compact.

Is my text sent to a server?

No — SHA hashes are computed using the browser's built-in Web Crypto API, and MD5 is computed with a pure-JavaScript implementation. Nothing leaves your browser.

Why Use This Tool?

Cryptographic hashes are used for data integrity verification, password storage, checksums, cache keys, and digital signatures. This tool generates multiple hash types simultaneously so you can compare them or pick the algorithm that fits your use case. SHA-256 is the industry standard for most security applications.
