Hash operations treat stack values as text

[rapodaca]

OP_ADD appears to treat stack items as hex values, as expected:

0x0a 0x06 OP_ADD 0x10 OP_EQUAL

However, it looks like OP_SHA256 (and OP_RIPEMD160) treats stack items as text. I expect this to fail (but it passes):

0x0a OP_SHA256 0xca978112ca1bbdcafac231b39a23dc4da786eff8147c4e72b9807785afee48bb OP_EQUAL

and this to pass (but it fails):

0x61 OP_SHA256 0xca978112ca1bbdcafac231b39a23dc4da786eff8147c4e72b9807785afee48bb OP_EQUAL

Ideas?

I suggest using bitcore's Script library. It is better maintained.
