    A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.

    Encryptron

    Encryptron

    An encryption software using C# 4.0

    First of all, let us understand the need for an encryption software. Just think of you sending a message of extreme confidentiality, someone else fetches it and goes through it. A breach in the security! We can’t allow that to happen. So, virtually every data send over a network is encrypted now-a-days. Let’s look at this now: Vdmbnld!`f`ho !Sdutsohof!whrhunsr!`oe!bnedsr-!une`x!H&l!fnhof!un!rinv!xnt!`o!houdsdruhof!unqhb!ui`u!hr-!inv!un!qsdq`sd!`o!dobsxquhno!rnguv`sd!trhof!B”!5/1!`oe!Vhoenvr!Gnslr/ Qsdsdpthrhudr!; 0/!Lhbsnrngu!Whrt`m!Rutehn/!) This is absolute fuzzy mess! That’s ‘encryption’ according to my software. Now feed this data back in the software you get usual form the plain English language. Put the same software at both terminals it may help in encoding and deciphering simultaneously
