AFS::KTC_EKEY(3pm)
NAME
AFS::KTC_EKEY - Class to handle the AFS structure ktc_encryptionkey
SYNOPSIS
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;
DESCRIPTION
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.
COMPATIBILITY
This release does NOT support any features and interfaces from version
1.
METHODS
CONSTRUCTOR
- $key = AFS::KTC_EKEY->des_string_to_key(STRING);
- 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'. - $key = AFS::KTC_EKEY->ReadPassword(PROMPT [, VERIFY [, CELL]]);
- 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'. - $key = AFS::KTC_EKEY->StringToKey(PASSWD, 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'. - CLASS METHODS
- $string = AFS::KTC_EKEY->UserReadPassword(PROMPT [, REASON]);
- 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'. - ATTRIBUTES ACCESS
- $key->string;
- Returns the whole encryption key as a string.
