When to use hashing?

The primary purpose of hashing is to encode plaintext values, transforming them into a seemingly random string of characters known as a hash value. This process ensures that the original information remains concealed and cannot be easily deciphered or exposed.

Hashing is a cryptographic function that plays a pivotal role in ensuring security, particularly within the realm of cybersecurity. It serves as a fundamental tool for safeguarding sensitive information from unauthorized access.

The use of hash values extends beyond mere encoding, however. They are also utilized for verifying the integrity of data. By comparing the hash value of a file or message with a previously generated hash, users can confirm that the content has not been altered or tampered with since the hash was initially created.

Hashing algorithms are designed to be one-way, meaning that it is practically impossible to reverse the process and retrieve the original plaintext value from the hash. This characteristic further enhances the security of hashed data, making it virtually impossible for attackers to uncover sensitive information.
