I wouldn't trust a compression algorithim, even if it is
keyed. They tend to use obscurity, rather than a good cryptosystem.
If your customer expects that a competitor might spend an hour
to break the encryption, then you want something stronger. (Not that
the algorithim will be broken in an hour, but many people, especially
outside the security field, underestimate the effort that will be put
into breaking a system.)
I find that a good basic test of encryption strength is if the
US government forbids its export. If its export is not forbidden,
then the encryption is very weak, and shouldn't be trusted.
