===Why use ed2k instead of another type of hash if you do not support downloads?!=== | |||
---- | |||
:* The combination of md4 hash and file size makes ed2k effective for uniquely identifying files. | |||
:* Since ed2k hashes can be passed back and forth within a URL with both the hash and file size in a widely recognized format it is a convenient method for adding or checking files. | |||
:* Other hashes are good for validating if a file is corrupt if you already know what file you are comparing it against, but cannot necessarily globally identify a file in the system like the ed2k. | |||
:* AniDB was designed around ed2k, although other hashes have been added to the file records for validation, the internal structure is based on ed2k. If the site goes through a complete redesign then maybe another hash will be made the primary hash, but at this point, this is not likely to change. | |||
