fs_getcrypt - Displays the state of encryption for Cache Manager operations


fs getcrypt [-help]


The fs getcrypt command displays the default encryption mode that the Cache Manager will use when communicating with File Servers and Location Servers via authenticated connections.

The actual use of encryption and the chosen encryption algorithm is determined by the existence of valid rxkad or yfs-rxgk tokens and the security policies (if any) applied to the File Servers.


When rxkad tokens are in use, network communications will be encrypted using an encryption algorithm called fcrypt. Fcrypt is based on DES but is slightly weaker. Fcrypt and DES are obsolete. Consider upgrading the cell to use yfs-rxgk to obtain support for AES256 encryption.

Encrypting file traffic requires a token. Unauthenticated connections or connections authorized via IP-based ACLs will not be encrypted even when encryption is turned on.



Prints the online help for this command. All other valid options are ignored.


If encryption is enabled, the output is:

   Security level is currently crypt (data security).

If auth is enabled, the output is:

   Security level is auth (data integrity).

If encryption if disabled, the output is:

   Security level is currently clear.


There is only one way to invoke fs getcrypt:

   % fs getcrypt


No special privileges are required for this command.
