Example

Input: hello
Result: SHA-256: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824

FAQ

No. Hash functions are one-way: it is computationally infeasible to recover the original input from a hash. This property makes them essential for security applications.

SHA-256 is the recommended default for most purposes. MD5 and SHA-1 are considered cryptographically weak and should not be used for security-sensitive applications.

No. All hashing runs entirely in your browser using JavaScript. No data is ever sent to our servers.

Verifying file integrity, storing passwords securely (with a salt), generating checksums, and detecting unauthorized data modifications.
