fs_getcrypt

FS_GETCRYPT(1)						       AFS Command Reference						    FS_GETCRYPT(1)

NAME

       fs_getcrypt - Displays the state of encryption for AFS file transfers

SYNOPSIS

       fs getcrypt [-help]

DESCRIPTION

       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.

CAUTIONS

       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.

OPTIONS

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

OUTPUT

       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.

EXAMPLES

       There is only one way to invoke fs getcrypt:

	  % fs getcrypt

PRIVILEGE REQUIRED

       No special priviledges are required for this command.
