About Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 digests from text for checksums, content fingerprints, and development tests. Do not use these fast general-purpose hashes for password storage; use a purpose-built password hashing function such as Argon2id, scrypt, bcrypt, or PBKDF2 with a unique salt.
MD5 is computed locally with SparkMD5, while the SHA variants use the browser Web Crypto API. The entered text is not sent to SavvyToolz. A digest by itself does not authenticate a message, create a digital signature, or safely store a password.
Frequently Asked Questions
- Are these hashes secure?
- SHA-256 and SHA-512 remain widely used for integrity checks and within well-designed security protocols, but a bare hash is not authentication or password protection. MD5 and SHA-1 have practical collision weaknesses and should be limited to compatibility or non-security checksums.
- Is my data sent to a server?
- No. MD5 is calculated locally with SparkMD5, and SHA-1, SHA-256, and SHA-512 are calculated locally with the browser Web Crypto API.
