  • RE: Does T-SQL have a means of iterating over the columns of a table?

    I'm assuming what you want to do is roll your own Change Data Capture, where you are capturing only those columns that changed within a row, and then insert into...

  • RE: Losing All Traces of Data

    If all the organization's databases and backups are encrypted, then a far more realistic scenario (although still improbable) is that an insider figures out a way to somehow copy and...

    splitting hairs.

    Losing the salt would be the equivalent of losing the symmetric key, if the domain is known. In the case of a social security...

  • RE: Losing All Traces of Data

    The "Right To Be Forgotten" is an interesting legal concept. Not only is it technically and logistically impossible, but apparently it doesn't apply equally to all individuals (ie: regular folks...

    at this point you might as well use symmetric key encryption instead of hashing.

  • RE: Storing encypted SSN's

    Post the SHA2_256 hash of any validly formatted plaintext SSN (ie: any code conforming to 999-99-9999), and I'll reply back with the un-hashed plaintext SSN number.

    For example use this:

    PRINT HASHBYTES('SHA2_512',...
