  SQL Server Tips by Burleson


To compile the class you will need Microsoft Visual C++ 6.0 or later installed.
You should also ensure that you have a recent MS Platform SDK installed and configured.

Follow the normal procedure to register the DLL. You should register all the XP’s as implemented in the module “XPCrypt.cpp” using the TSQL statement “sp_addextendedproc”.

A lot of the XP’s return a variable sized output parameter e.g. the encrypted data, signature, hash or HMAC. To determine the maximum size for these variables you should call the function using the maximum size of data for the input and use the size of the output parameter for your definitions. This ensures that output data does not get truncated. Also since the encrypted data can be bigger than the plaintext input parameters, special care must be taken when designing tables which will stored encrypted data so that they will not cause problems with the inherent limit of 8000 characters in TSQL.
