email hash

[Jaez]

My users are entering their email address as one means of authenticating
their account

I need to store but also protect their email addresses in a sql database

can I use HashPasswordForStoringInConfigFile but as this hashes to 160bits
I guess there must be a limit as to its input string length

Any ideals welcome

Jaez,

For the best protection, you should store usernames and passwords in the
database using a one-way hash.

Hope this helps,
