Aes-ctr for fast crypto
-
As per the latest blog piece, what is the status on AES-CTR (Counter mode) support for IPsec? OpenSSH prefers counter mode by default and the performance is quite significant compared to CBC mode.
OpenSSL speed benchmark example:
type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 467308.07k 519446.61k 539072.85k 542258.86k 543350.78k aes-128-ctr 372502.28k 1076462.27k 1883048.79k 2410511.36k 2672528.04k aes-128-gcm 241830.67k 583661.95k 765165.91k 840589.65k 837268.82k camellia-128-cbc 71470.59k 109661.25k 127749.63k 134138.54k 135187.11k
