- Yes, it is, assuming MD5 is a one-way function.

- Exponentiation is also exportable. With it, you can make RSA -- and make
- it as strong as you like by making the radix larger.
-
- It's the code using MD5 or exponentiation which would be the encryption
- code -- not the digest or exponentiation code itself.
