3 Byte output hashing algorithm

So for a project that I am working on, I am trying to get a hashing algorithm but I don't know anything about hashing algorithms. The final outcome I would like to archive is inputing a 6 byte value and get 3 unique bytes as my output.

My other alternative is one algorithm that inputs a 2 byte value and outputs 1 unique byte.

Is this possible?

** Edit: I would need this in C language if possible or pseudo code.

Most hash functions can take arbitrary numbers of bytes since they are by nature compression functions. As for the output, you can just take the first 3 bytes of the output. Any cryptographically safe hash function will output bytes that are suitable for this.

For example, in Python it would be:

from hashlib import sha256

s = sha256(<your bytes>)
output = s.digest()[:3]
