I'm leaning towards RSA too, but I wish I could remember the specifics about why it's preferred for digital signatures.

Okay, I've got it! Rijndael is the same as AES, which is a great choice for signing certificates because of its strong security and widespread adoption. I'm confident that's the right answer.

Diffie-Hellman is for key exchange, not digital signatures, so I can rule that one out. I think it's between RSA, Rijndael, and RC6 for this question.

I'm a bit confused on the differences between Rijndael and RC6. Are they both block ciphers? I'll need to review the properties of each one to decide which is more appropriate for this use case.
