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. SEE ALSO

FS_SETCRYPT(1) AFS Command Reference FS_SETCRYPT(1) NAME
fs_setcrypt - Enables of disables the encryption of AFS file transfers SYNOPSIS
fs setcrypt [-crypt] <on/off> [-help] DESCRIPTION
The fs setcrypt command sets 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 File Server for users with valid tokens. This command does not control the encryption used for authentication, which uses Kerberos 5 or klog/kaserver. The complement of this command is fs getcrypt, which shows the status of encryption on the client. The default encryption status is enabled. This is a global setting and applies to all subsequent connections to an AFS File Server from this Cache Manager. There is no way to enable or disable encryption for specific connections. CAUTIONS
AFS uses an encryption scheme called fcrypt, based on but slightly weaker than DES, and there is currently no way to specify a different encryption mechanism. 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
-crypt <on/off> This is the only option to fs setcrypt. The -crypt option takes either "on" or "off". "on" enables encryption. "off" disables encryption. Since this is the only option, the "-crypt" flag may be omitted. 0 and 1 or "true" and "false" are not supported as replacements for "on" and "off". -help Prints the online help for this command. All other valid options are ignored. OUTPUT
This command produces no output other than error messages. EXAMPLES
There are only four ways to invoke fs setcrypt. Either of: % fs setcrypt -crypt on % fs setcrypt on will enable encryption for authenticated connections and: % fs setcrypt -crypt off % fs setcrypt off will disable encryption. PRIVILEGE REQUIRED
The issuer must be logged in as the local superuser root. SEE ALSO
