128 bit Mobile Device Security algorithms

SHA1 algorithm 64 bit or 128 bit

Please suggest which is best

What are your parameters? It should be obvious that the more bits, the less
breakable the security will be and the more processing power needed to
encrypt/decrypt the messages.

Another thing to consider is that certain algorithms or bit lengths might
have export regulations for certain countries.

And a third thing to consider is that older devices might not support high
encryption.

And if the device does support it, it might be really, really slow.
