Thank you for your comment. The reason I use my own database is that it allows me to store the data as compact as possible and also allows me to control better what is stored. I'm sure the CDB system is fast and everything, but I doubt it comes any faster since I preload everything into memory before starting to process. The in-memory data is stored in more or less efficient hashtable allowing near O(1) acccess times.
Interesting project.
Hi! Interesting work. Good idea to use openssl
for digests.
As I understand you use own database format,
to store file data (checksums,stat
information,etc.).
It may be interesting for you:
osec - it's mine integrity checker, that uses CDB
for database. CDB works faster then others.

CDB mmap() all data into memory, so it's fast
enough.
This is very efficient, 'cause it is a Constant
(Read-only or Write-only).
It also uses hashtable to made access faster.
Size of database is small, cause it have
read-only/write-only design.
