-## Purpose
+### Purpose
 
-provide the password needed to open the encrypted private key file
+- provide the password needed to open the encrypted private key file
 (/var/flash/websrv_ssl_key.pem) from FRITZ!OS versions above 06.20
-
+- new version computes the password itself from ```maca``` value
+- no more hassle with static vs. dynamic linking and/or using the proxy binary
+- the project contains a library (shared and static), the exported functions are backward-compatible with previous version(s)
+- some function from previous versions are useless now and are implemented as 'dummy function'
+- the computation of MD5 hashes (in md5.c) was copied (with some minor changes) from the uClibc sources - the (default) libuclibc/libcrypt does not export the needed functions, so they were duplicated here
+- the provided binary ```privatekeypassword``` may be used from other programs (or shell scripts) to get the clear-text of the password for the private key file
