I am trying to implement JavaScript interpreter for Bitcoin scripts, but I have problem with counting value of OP_HASH160. I found that
Hash160(x) = RIPEMD160(SHA256(x))
However, when I try to count it this way using CryptoJS library, I get different value than on page http://paulkernfeld.com/bse/.
CryptoJS.RIPEMD160(CryptoJS.SHA256("02c34538fc933799d972f55752d318c0328ca2bacccd5c7482119ea9da2df70a2f")).toString() = "e81794c3da1564a196665dd0f74483185f524fe2"
where "02c34538fc933799d972f55752d318c0328ca2bacccd5c7482119ea9da2df70a2f" is the first element on the top of the stack.
Could somebody explain how exactly operation OP_HASH160 works?
Thx! :)
