How is a hash verified?

If the two hash values match, it signifies that the data has remained unchanged since the initial hashing process. This indicates that the data's integrity has been maintained, and it can be trusted for further use or analysis.

Data integrity is a crucial aspect in ensuring the authenticity and reliability of information. One method to verify the integrity of data is by comparing it to a hash value. A hash value is a unique numeric representation of the data that is generated using a cryptographic hash function.

The process of hashing data involves converting the data into a fixed-size alphanumeric string that serves as a unique identifier for the data. This hash value is generated at a specific point in time and is then protected or stored securely.

Later on, when the need arises to verify the integrity of the data, it can be hashed again using the same cryptographic hash function. The newly generated hash value is then compared with the protected hash value.
