I'd have to agree with Fletch. Also, compression algorithms normally produce binary data which would cause issues when used in string context (null characters) leading to, at a minimum, collisions. Also I don't think MD5 or SHA1 will buy you much savings giving the string lengths you're talking about.

Update: As jethro points out ... I was confusing C strings with perl strings ... silly me.
