Hi: > I think you should look for CONFIG_CRYPTO_CHACHA20POLY1305 in the kernel > config.
after trying and testing, I found besides "CONFIG_CRYPTO_CHACHA20POLY1305", I also need "CONFIG_CRYPTO_LIB_POLY1305" and "CONFIG_CRYPTO_LIB_CHACHA". ovpn-dco will auto-load the three modules when doing CHACHA20POLY1305. at RHEL9 the later two are compiled into kernel directly, so only module CHACHA20POLY1305 module will be auto-loaded. maybe ovpn-dco should make dependency with these modules directly like wireguard. the device can do "100Mbs/60Mbps" upload/download speed with chacha20 dco. it seems dco is good at encryption, but not so good at decryption(wireguard can do 300Mbps). as a client normally I want fast decryption. is there parameter I can tune for faster decryption? _______________________________________________ Openvpn-users mailing list Openvpn-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-users
