HASHBYTES is one of the useful functions when it comes to generate hash values on the basis of different types of algorithms. From MS SQL server version 2012 additionally the SHA2_256, SHA2_512 algorithms were introduced. I have been using hashbytes for a long time and at best convert them to char, for ease of use, but not to bigint. fn_varbintohexstr(HashBytes('MD5', 'HelloWorld')), 3, 32). I want to get the MD5 Hash of a string value in SQL Server 2005. Errors of the Severity Level 16 are generated by the user and can be fixed by the SQL Server user.

SQL Server 2016, which at the time of this writing is in a Release Candidate 0 state of readiness, has been changed to handle several of these best practices. The real answer is a true hashing function, and in SQL Server that means HASHBYTES. Before we look at “Trusted Assemblies”, let’s take a moment to review the context of the situation. Consider using HashBytes instead.
