I am having trouble with flickr short urls, specifically those generated for sets.
Photos
I can see that for individual photos, if I select share and get the short url, they I would get flic.kr/p/{base58_encode(photoid)}. I can easily decode and encode the photoid and get the correct values.
Sets
I have tried the same for sets. If I select share on a set and get the short url, then I would get something like flic.kr/s/{base58_encode(setid)}. However, I am not sure that it is base58 encoded this time as decoding/encoding setid's with a base58 encoder/decoder does not return the correct values.
So, the question is, are the setid's encoded with a different encoder, or is there some sort of salt used with sets?
Many thanks in advance.
