In Excel and Word 95 and prior editions a weak protection algorithm is used that converts a password to a 16-bit verifier and a 16-byte XOR obfuscation array [1] key. [4] Hacking software is now readily available to find a 16-byte key and decrypt the password-protected document. [5] Office 97, 2000, XP and 2003 use RC4 with 40 bits. [4]
When the client sends a clear-text password, the authentication server will receive it, and compare it to a "known good" password. Since the authentication server has received the password in clear-text, the format of the stored password can be chosen to be secure "at rest". If an attacker were to steal the entire database of passwords, it is ...
Since the authentication server has to store the password in clear-text, it is impossible to use different formats for the stored password. If an attacker were to steal the entire database of passwords, all of those passwords would be visible "in the clear" in the database.
PPPoE is used to connect a PC or a router to a modem via an Ethernet link and it can also be used in Internet access over DSL on a telephone line in the PPPoE over ATM (PPPoEoA) over ADSL protocol stack. PPPoE over ATM has the highest overhead of the popular DSL delivery methods, when compared with for example PPPoA (RFC 2364). [11] [12] [13] [14]
RFC 2364 describes Point-to-Point Protocol over ATM (PPPoA) as a method for transmitting PPP over ATM Adaptation Layer 5 , which is also a common alternative to PPPoE used with DSL. PPP, PPPoE and PPPoA are widely used in WAN lines. PPP is a layered protocol that has three components: [4]

kppp – A kde GUI frontend for pppd.; gnome-ppp – A (discontinued) gnome GUI frontend for WvDial, which in turns depends on pppd.; pppconfig – It uses the standard ppp configuration files and sets ppp up so that the standard pon and poff commands (to connect and disconnect) and plog (to list the log) can be used to control ppp.
PPP configuration generally includes: user credentials, user name and password, and is unique to each user. ATM configuration includes: Virtual channel link (VCL) – virtual path identifier and virtual channel identifier (VPI/VCI), such as 0/32 (analogous to a phone number) Modulation (Type): such as G.dmt; Multiplexing (Method): such as VC ...
