THE INFORMATION IN THIS ARTICLE APPLIES TO:
SYMPTOM
EFT records incorrect MAC when Ciphers AES128-GMC and AES256-gmc are used
CAUSE
The ciphers aes256-gcm@openssh.com and aes128-gcm@openssh.com contain the integrity check inside itself. With OpenSSH, there no need to use any other "explicit" MAC algorithm.
MORE INFORMATION
The logs are expected to be made clear in a subsequent EFT release.
