In Java, you can use Expression.Sql, the same should work in C#, something like:

var table = session.CreateCriteria(typeof(Table))
            .Add(Expression.Sql("MD5(column)= ?", value, NHibernateUtil.String))
            .UniqueResult<Table>();

where value is the hex-encoded value of your MD5 hash.

Although, one word of caution - if the value stored in the database is the user's password, then your design is flawed and insecure. You should only store salted, hashed passwords in the database. No, you shouldn't even do that, you should right away use bcrypt, scrypt or PBKDF2 for that.
