I have been a subscriber on the DBA-Village newsletter for quite a few years now and every Sunday night I get an email that lists at the top some useful links, a pole and all of the threads on the forum since the last email. DBA-Village is quite a useful site but to view the content you must register. The registration is free.
There was a useful link this week to a short PL/SQL function that can be used to return the MD5 sum of a string. Running a checksum of any data held in the database that is critical can be a useful thing to do. Also check summing the data dictionary or just the PL/SQL held there can also be a useful task to ensure that the dictionary has not been altered by a hacker for his own purposes.
The page on DBA-Village is titled "Returning MD5 hash", the function is clean and simple.
