Public bug reported: Due to the lack of HW accelerated AES, ChaCha20 is currently the most efficient cypher for Raspberry Pi4 users. It is enabled in the current 5.4 ubuntu kernels but unfortunately without CONFIG_CRYPTO_NHPOLY1305_NEON
CONFIG_CRYPTO_CHACHA20_NEON=m # CONFIG_CRYPTO_NHPOLY1305_NEON is not set The performance is significantly reduced as indicated in https://github.com/raspberrypi/linux/issues/3648#issuecomment-644251745 ----- Description: Ubuntu 20.04 LTS Release: 20.04 Linux rpi4 5.4.0-1014-raspi #14-Ubuntu SMP Sat Jul 4 10:25:33 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux ** Affects: linux-raspi (Ubuntu) Importance: Undecided Status: New ** Description changed: - - Due to the lack of HW accelerated AES, ChaCha20 is currently the most efficient cypher for Raspberry Pi4 users.
