Generate Secret Key from Password

The GenEncodedSecretKey method provides a way to produce a secret key from an arbitrarily sized password string. The secret key produced will be equal in bit length to the KeyLength. A given string passed to GenEncodedSecretKey will always produce the same key. (In other words, this is really a hash function and not a random key generator.)
