Tell me, how are hash functions like SHA1 used to secure webpages in SSL? I'm looking at hashes on HTTPS certificates, but they're meaningless to me.

Well, my hash function isn't meant for security purposes, but is meant for putting entries into a list without having to search through the whole list of items. Hashcodes assign an index of an entry into a particular index of an array. Since a hashcode % arraysize can have similarities, there are collisions.

http://en.wikipedia.org/wiki/Cryptographic_hash_function I think the way it works is the hashcode function is one-way, therefore the hash values are not decryptable. That is just my interpretation of it, though.
