+Microsoft PPP compression/encryption (MPPC/MPPE)
+CONFIG_PPP_MPPE_MPPC
+ Support for the Microsoft Point-To-Point Compression (RFC2118) and
+ Microsoft Point-To-Point Encryption (RFC3078). These protocols are
+ supported by Microsoft Windows and wide range of "hardware" access
+ servers. MPPE is common protocol in Virtual Private Networks. According
+ to RFC3078, MPPE supports 40, 56 and 128-bit key lengths. Depending on
+ PPP daemon configuration on both ends of the link, following scenarios
+ are possible:
+ - only compression (MPPC) is used,
+ - only encryption (MPPE) is used,
+ - compression and encryption (MPPC+MPPE) are used.
+
+ Please note that Hi/Fn (http://www.hifn.com) holds patent on MPPC so
+ you should check if this patent is valid in your country in order to
+ avoid legal problems.
+
+ For more information please visit http://free.polbox.pl/h/hs001
+
+ To compile this driver as a module, choose M here. The module will
+ be called ppp_mppe_mppc.o.
