If you haven’t already, please send take the anonymous feedback form for the class (this is the same form linked on the last daily post).

If you didn’t complete the RSA ciphertext chain from last daily post, please catch up now (it’s an important one to get a handle on). Click back for instructions.

Use Fermat’s Primality Test to detect whether 2001 and 2003 are composite or probably prime. Show your work (but you can use a calculator like Sage for the exponentiation).

If one of them is probably prime, then try a different a and explain what you learn.
