I don't know if ASN.1 is turing complete, but I don't think Simplicity can handle arbitrary depth recursion, either. Luckily, to parse a BER coded certificate, you only need a fixed depth. Of course, if you are actually parsing BER in a smart contract, you should really reconsider what life choices brought you to this point :) But it might be useful for a non-blockchain related crypto library.
