Generate checksums for text and files, with clear guidance on safe hash use.

Processed locally for this tool. This transformation does not submit its input or output to Laravel. See the privacy policy for the site's wider data practices.

Security note: Base64 and URL encoding are reversible and provide no secrecy. SHA-256/SHA-512 are useful for checksums, not password storage. Use a password-specific function such as Argon2id, scrypt or bcrypt for stored passwords.
