AES-GCM в клиенте IPSec

Recommended Posts


IPsec: добавлены AEAD-шифры в IKE и ESP: AES-CCM и AES-GCM (частично ускоряются аппаратно EIP93), CHACHA20-POLY1305

Обновился на 3.5.1. Увидел в changelog поддержку новых шифров.

Как включить AES-GCM или даже лучше ChaCha/Poly?

Я использую IPSec клиент вместе с тоннелем Gre. Настроил ipsec-encryption-level: high.

В результате на сервере (strongSwan) получаю AES_CBC-256/HMAC_SHA2_256_128

PS - у меня Keentic Ultra 907-566-601-126-887

PPS - на сервере настроены

version = 2

proposals = aes256-sha256-ecp256,aes256-sha1-modp2048,aes256-sha256-modp2048,aes256gcm16-sha256-modp2048

esp_proposals = aes256gcm16-sha256-ecp256,aes256ctr-sha256-ecp256,aes256-sha1-modp2048,aes256-sha256-modp2048,aes256gcm16-sha256-modp2048
