  • ONTAP 9
  • CIFS

Answer

The SMB encryption supported in ONTAP 9 is as follows:

  • AES-128-CCM encryption is supported（SMB 3.X）
  • AES-128-GCM encryption is supported（SMB 3.1.1）
  • AES-256-GCM encryption is not supported
  • AES-256-CCM encryption is not supported

Additional Information

The encryption support for protocols other than SMB (such as SSH, TLS, NFS, etc.) is as follows:

  • For SSH, the following encryption methods can be specified:

aes256-ctr
aes192-ctr
aes128-ctr
aes256-cbc
aes192-cbc
aes128-cbc
3des-cbc
aes128-gcm
aes256-gcm

 

  • AES-128-CCM is not supported for SSH.
  • Regarding TLS, a specific list of encryption methods is not provided, but the standard encryption methods used in TLS 1.2 and TLS 1.3 are generally supported.
  • For NFS, a specific list of encryption methods is not provided, but encryption is supported in NFSv4.1 and NFSv4.2.
