  • zfsEncryption_SpeedTest

    Compares I/O speed on RAM-backed temporary ZFS datasets (unencrypted ZFS, ZFS native encryption, and ZFS over LUKS) datasets using fio

    • HERE is a link to the code (hosted on github)

  • zfs

    OpenZFS on Linux and FreeBSD

    • I actually ended up doing this. I think I may have found a bonafide bug having to do with how ZFS native encryption uses the ARC to cache data.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • LUKS2-docs

    • this is the authoritative source on what the LUKS header (the only unencrypted LUKS part) contains. Im not going to copy/paste all the details (the document is very specific), but it basically comes down to
