CRC32 Checksum How to in Player Profile

[cybernine186]

I have developed a tool for viewing/editing the player profile in the character_ table. The viewing and editing works for int values only (Which almost every value seems to be a numeric value) but I am having trouble trying to figure out how the CRC32 check works. So far from my research the CRC32's value runs off the sizeof value. I am using PHP and it has build in capabilities for CRC32 and sizeof. Can anyone help me or point me in the right direction of being able to recreate the checksum in the player profile in the database or is the checksum totally worthless to the EQ client?
