This class provides methods to handle the AFS structure ktc_encryptionkey. This structure represents an encryption key which is used in the Kernel Token Cache (KTC). The KTC is part of the Cache Manager. It is used to create ktc_encryptionkey instances.
In version 2, some of the methods have been renamed. All old names and interfaces from version 1 are still available for compatibility, but are deprecated. These cases have been marked in the documentation.
You must not intermix names or interfaces from version 1 with names or interfaces from version 2. You either stick with version 1 or version 2.

-----------------------------------------------------
ka_ReadPassword AFS::KTC_EKEY->ReadPassword
ka_UserReadPassword AFS::KTC_EKEY->UserReadPassword
ka_StringToKey AFS::KTC_EKEY->StringToKey
ka_des_string_to_key AFS::KTC_EKEY->des_string_to_key
The STRING string is converted to a DES encryption key and this key is returned as an AFS::KTC_EKEY object. It calls the AFS system library function 'des_string_to_key'.
NOTE: this form is deprecated !!!
$key = ka_des_string_to_key(STRING);
Prints out a PROMPT and reads a string from the terminal, turning off echoing. If VERIFY (default 0) is set to 1 it requests that the string be entered again and the two strings are compared. CELL defaults to NULL. The string is then converted to a DES encryption key and the encryption key is returned as an AFS::KTC_EKEY object. It calls the AFS system library function 'ka_ReadPassword'.
NOTE: this form is deprecated !!!
$key = ka_ReadPassword(PROMPT, VERIFY, CELL);
The PASSWD string is converted to a DES encryption key and this key is returned as an AFS::KTC_EKEY object. It calls the AFS system library function 'ka_StringToKey'.
NOTE: this form is deprecated !!!
$key = ka_StringToKey(PASSWD, CELL);
Prints out a PROMPT and reads a string from the terminal, turning off echoing. This string is returned. On error the error message is returned in REASON. It calls the AFS system library function 'ka_UserReadPassword'.
NOTE: this form is deprecated !!!
$string = ka_UserReadPassword(PROMPT, REASON);
Returns the whole encryption key as a string.
