I see webwiz is getting to 160bit encryption, I am to understand some countries have limits to encyrption in terms of lengths of bits, do you know what the limits are anyone?

The limits are only for personal encryption like PGP, not for website databases.

Can i ask about encryption?

Does 160bit mean theres 160bits per bit of encrypted data?

160bits is the size of the encryption KEY that is used in the algorythm to change or rather encrypt the original data.

It means that there are 2^160 possible keys that could fit the "lock" where the password is stored.

The algorythm expands 16 32-bit words of message text to 80 32-bit subkey words. And, after 80 rounds of the hash function are applied to the 160-bit value, the original value and the result value are combined together (using 32-bit addition with no carries between words) to make the hash operation noninvertible.

Hashing isn't really encryption because it's one-way, and there are no export/import/use restriction on hash functions (since you can't use that to store or send encrypted messages, only check for integrity).
