Guide & best practices

Hash Generator for checksums and password hashing

Calculate hashes, compare output and understand which algorithm fits checksums, integrity or passwords.

Useful for text checksums, API signatures, integrity checks, password-hash demos and legacy algorithm reviews.

Local hashes are computed in the browser; password-hashing functions use available implementations and explicit parameters.

Do not use MD5/SHA-1 for security. Use salted slow password hashing such as BCrypt/PBKDF2 and document parameters.

Which hash is suitable for passwords?

Use slow salted schemes such as BCrypt, PBKDF2 or modern KDFs.

Can SHA-256 be decrypted?

No. Hashes are one-way, but weak inputs can be guessed.

Is MD5 still useful?

Only for non-security legacy checksums, not authentication or integrity protection.

Which tools complement it?

Secret Generator, JWT Decoder and Hex Checksum.
