Well, there you go... So use SecureHashAlgorithm instead. On my little-endian
machine, BTW, this is what happens:
(SHA1 new hashMessage: 'ede8557d-8e2f-11d9-8a80-000a95e87d06tonyg') hex
'52FBE248257F325B5CEEBA8B2278A9A28442F8D6'
(SecureHashAlgorithm new hashMessage:
'ede8557d-8e2f-11d9-8a80-000a95e87d06tonyg') hex
'16rD6F84284A2A978228BBAEE5C5B327F2548E2FB52'
