And presumably has been tested against injection attacks (implied by 
your use of 'secure.')

JM:  That's the flip side.  If you CAN find some open-source that 
exactly meets your needs, it presumably has had lots of eyes on it to 
spot the little bugs that are likely to pop up in any new implementation.

There's a vast grey area between

1) so simple it's safer to do it myself


2) so complex the open-source version must have bugs, so I'd better do 
it myself.

in between, you use the open-source code or library.

But this is why I always start by trying to narrow the choice of what 
you *need*.

...the only secure system is one physically contained in a room with a 
padlock, and with a guard.  And only if the guard is yourself...
