What is the use of the rraes package and why it it not used for f1 #21

I'm studying the Chia proof of space construction and your implementation is a lifesaver. But I don't fully understand why the rraes package exists. Is it a custom aes implementation that you wrote, why is that necessary? And why is it not used for F1? Maybe I'm missing something in the chia docs.

Thank you,

The first version of the Chia PoSpace algorithm used AES and a reduced rounds version of it (RRAES) to generate the proofs. They have switched to ChaCha8 and BLAKE3 since I finished my PoC.

Glad you have found my implementation useful btw!
