While the best VPNs (like ExpressVPN, NordVPN and Surfshark) rely on an AES-256 encryption, there are a number of outdated services that still rely on PPTP and What key size is used for AES (#1) and in which mode it is run (CBC/ECB/..)? HMAC-SHA-256 and AES will give the same sized output regardless of whether 128 bit or 256 bit keys are used. This should use the KDF with SHA-256 and AES with 256 bit key size. aes-256-ecb" option specifies the version of the AES algorithm which uses 256-bit keys. a.
