Encryption Levels on the Cryptography Activities Pack

Hello,

In regards to the Cryptography Activities Pack. I was hoping to find what level of security is being used in the package. It lists algorithms such as AES, DES, RC2, Rijndael , and TripleDES, but doesn’t mention if it’s using 256-bit or 128-bit.

Does anyone know what the bit level of encryption is being used?

EDIT: More specifically is the AES encryption = AES-256 (this is the minimum I need to follow company standards)

Thanks!

NOTE: I am aware that this activites pack is now open source, but I was hoping someone here might know.
