If you don't find any official degree online you can always stick to a bootcamp course that is similar to Harvard Math 55. It has had several forms. The most interesting ones being either Halmos + Rudin (plus many aids such as Gelbaum & Olmsted) or just Hubbard & Hubbard. Either way you will get a very solid introduction to mathematics that covers algebra and analysis, in a really rigorous way.

However, being a computer scientist I think a different approach to mathematics can be more enjoyable and also much more useful for many theoretical and practical developments that are yet to come. The downside is that materials are a lot less cohesive (any other references appreciated!). I'm talking about an approach with a focus on the foundations of mathematics, emphasizing logic, category theory and type theory.
