Not necessary. The xtea, xxtea don't fix mixing portion of tea in accordance with the
following papers: http://algolist.manual.ru/defence/well_known/tea.zip
Nop ;)No doubt there is no ideal hash algo, but if base algo has weaknes, using fixed one only can be better, Right ?
We don't need to keep a track of teacore upgrades against the attacks that allow to reveal secret key.
Tea hash uses tea algorithm only for mixing, not for private ciphering, so plain text is known
(this is hardcoded vector u32 k[] = { 0x9464a485, 0x542e1a94}), keys (constructed by names)
are known, output values are known.
Nothing to reveal - nothing to upgrade..
