What type of checksum?
All downloads from WinWorld Library have checksums attached to check file integrity. I have not found what type of checksum it is. Even checksum type detectors are not able to determine what type it is. Is it MD5, SHA1 or something different? It would be nice to replace the string "Checksum:" with "[TYPE] Checksum:" eg. "MD5 Checksum:". Not really on topic: I have some time ago tried to check download checksum. Not only I have not found what type it is, but even after trying all possible checksum types none was matching. It looks like there is some technical problem with download checksums.
