Frequently Asked Questions
A checksum is a small-sized datum derived from a block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage.
While you can, it is highly recommended to use strong salted hashes like bcrypt or Argon2 for passwords rather than simple checksums or fast hashes like MD5.
No, checksums are not perfectly unique. However, the probability of two different inputs having the same checksum (a collision) is extremely low for algorithms like SHA256.
