+Subject: [PATCH] pppd: Use openssl for the DES instead of the libcrypt / glibc
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It seems the latest glibc (in Fedora glibc-2.27.9000-12.fc29) dropped
+libcrypt.  The libxcrypt standalone package can be used instead, but
+it dropped the old setkey/encrypt API which ppp uses for DES.  There
+is support for using openssl in pppcrypt.c, but it contains typos
+preventing it from compiling and seems to be written for an ancient
+openssl version.
+
+This updates the code to use current openssl.
+
+[paulus ozlabs org - wrote the commit description, fixed comment in
+ Makefile.linux.]
