===FNV-0 hash (deprecated)===
The FNV-0 hash differs from the FNV-1 hash only by the initialisation value of the ''hash'' variable:<ref name= FNV_basics /><ref name=FNV0>{{Cite web|url=http://www.isthe.com/chongo/tech/comp/fnv/index.html#FNV-0|title=FNV Hash - FNV-0 Historic not|website=www.isthe.com}}</ref>

 '''algorithm''' fnv-0 '''is'''
     ''hash'' := 0
 
     '''for each''' ''byte_of_data'' to be hashed '''do'''
         ''hash'' := ''hash'' × '''''FNV_prime'''''
         ''hash'' := ''hash'' [[XOR]] ''byte_of_data''
 
     '''return''' ''hash''

The above pseudocode has the same assumptions that were noted for the FNV-1 pseudocode.

A consequence of the initialisation of the hash to 0 is that empty messages and all messages consisting of only the byte 0, regardless of their length, hash to 0.<ref name=FNV0 />

Use of the FNV-0 hash is [[deprecated]] except for the computing of the FNV offset basis for use as the FNV-1 and FNV-1a hash parameters.<ref name= FNV_basics /><ref name=FNV0 />
