This seems like it would work, because if the hashes are truly unique, the only way, it seems, without brute forcing, to decrypt the data would be to use the same hash as what you used to encrypt it.
WebHashing is an engineering problem and the primary challenge is an efficiency one - how to make it expensive to find the password given the hash. One of the principle results of that kind of thinking is the importance of making password hashes slow. And the science and mathematics of hashing is only slowly getting better. WebMar 23, 2024 · Data Hashing can be used to solve this problem in SQL Server. A hash is a number that is generated by reading the contents of a document or message. Different messages should generate different hash values, but the same message causes the algorithm to generate the same hash value. The HashBytes function in SQL Server
