Specifying custom hash alphabet

[Edijae]

I have extracted the below extract from your main page

Here we set the alphabet to consist of only four letters: "0123456789abcdef"
Hashids hashids = new Hashids("this is my salt", 0, "0123456789abcdef"); String hash = hashids.encode(1234567L);

hash is now going to be:
b332db5

the alphabet consists of 6 letters! a,b,c,d,e,f

any problem? the algorithm designed as you only need [0-9] and [a-f] chars?

@fanweixiao what @gikarasojo is trying to say is that we state that:
only four letters, but actually we have six.

@0x3333 @gikarasojo Oh, I see! yep, should be six, haha
