fs_getcrypt - Displays the state of encryption for AFS file transfers
fs getcrypt [-help]
The fs getcrypt command shows the status of network traffic encryption for file traffic in the AFS client. This encryption applies to file traffic going to and coming from the AFS server for users with valid tokens. The complement of this command is fs setcrypt which sets the status of encryption on the client.
AFS uses an encryption scheme called fcrypt, based on but slightly weaker than DES. Because fcrypt and DES are obsolete, the user must decide how much to trust the encryption. Consider using a Virtual Private Network at the IP level if better encryption is needed.
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.
If encryption is enabled, the output is:
Security level is currently crypt (data security).
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.
