  1. Regarding your question, ‘How is it calculated’, it’s an SHA1 hash.

    From dot net blog:

    Microsoft solves the ‘public key bloat’ problem by using a hash of the strongly-named assembly’s public key. These hashes are referred to as public key tokens, and are the low 8 bytes of the SHA1 hash of the strongly-named assembly’s public key. SHA1 hashes are 160 bit (20 byte) hashes, and the top 12 bytes of the hash are simply discarded in this algorithm.
