"WebSHA1's resistance to birthday attacks has been partially broken as of 2005 in O (2^64) vs the design O (2^80). While hashcash relies on pre-image resistance and so is not vulnerable to birthday attacks, a generic method of hardening SHA1 against the birthday collision attack is to iterate it twice.
