This tool implements the MD5, SHA-1 and SHA-256 algorithms directly, no crypto library involved, and each was verified to produce byte-identical output to Node's built-in crypto module across empty input, unicode text, and inputs at the algorithms' internal block-size boundaries before being wired up here.
MD5 and SHA-1 are fast but considered cryptographically broken, both have known collision vulnerabilities and shouldn't be used for security-sensitive purposes like password storage, though they're still common for non-security uses like checksums and cache keys. SHA-256 is currently considered secure and is the standard choice for security-relevant hashing today.
No, none of these algorithms (including SHA-256) should be used directly for password storage, dedicated password hashing algorithms like bcrypt, scrypt or Argon2 (which are deliberately slow and salted) exist specifically for that purpose. These general-purpose hashes are best suited for checksums, cache keys, and data integrity checks.
No, all hashing happens entirely in your browser, your text is never transmitted anywhere.
