Find hash algorithm?

Question

I'm trying to find out which method of hashing was used to generate certain strings. It's 32 bits (4 Bytes).

Found out it was DBJ v1. Any idea how to implement in C#? Thanks :)

Example Hashes: 00 02 B5 D5 - hash 30 - string

35 A0 FD 6A - hash 6F 66 66 65 6E 73 69 76 - string

05 7B DC 6C - hash 70 6C 61 79 65 72 20 75 73 65 64 20 6F 66 66 65 6E 73 69 76 65 20 6C 61 6E 67 75 61 67 65 - string

This is important so thank you!
