AFS::KTC_EKEY - Class to handle the AFS structure ktc_encryptionkey
use AFS::KTC_EKEY; use AFS::Cell qw(localcell); my $key = AFS::KTC_EKEY->ReadPassword('Password:'); print 'KEY = ', $key->string, " \n"; my $string = AFS::KTC_EKEY->UserReadPassword('Password:'); $key = AFS::KTC_EKEY->StringToKey($string, localcell); print 'KEY = ', $key->string, " \n"; $key = AFS::KTC_EKEY->des_string_to_key('aaa'); print 'KEY = ', $key->string, " \n"; undef $key;
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.
This release does NOT support any features and interfaces from version 1.
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'.
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'.
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'.
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'.
Returns the whole encryption key as a string.
