This is great, but is it supported in hardware or general-purpose CPU?  Also, when will this arrive for XC?

    Hi Walter_Kacynski​ , 
    To make sure, I got your question right, if you need specific hardware to get PQC enabled, it's no, as long as you switch to v17.5+ you are able to use the new ciphers. Here;s the KB for the hardware/software compatibility 
    https://my.f5.com/manage/s/article/K9476 

    The current implemented standard is to make sure a compatiblity exist with classic cryptography, by using ECDH algorith encapsulated with Quuantum resistent cipher. 

    For XC query, let me check on this one and get back to you

        Does F5 have any benchmarks on how much CPU will be consumed by activating these new ciphers on R-Series?
