One of the primary strengths of SHA-256 lies in its resistance to collision attacks. This means it is highly unlikely for two different inputs to produce the same hash output.

Password hashing is another application of SHA-256. By converting passwords into complex hash values, it enhances the security of user credentials, making it more difficult for attackers to crack them.
