Vernash

Encryption (Step By Step)




vernashCrypt()
public string vernashCrypt(byte[] text, string key, bool saveToFile, string filename)

Vernash(“Lorem ipsum dolor sit amet, consectetur adipisici elit, sed eiusmod tempor incidunt ut labore et dolore magna aliqua.”, “passphrase”) ==>
“UUYE>K>OEJG@9YADYW@X@7>R;P446T77?E471SV28<5CYN9H3U41W@XT?>7B<@35A@1R:MVH98WFWXESH?E@@@>F>40D0R<0A85?2LF....”

Step 1: randomExpansion(byte[] text)



randomExpansion(“Loerm ipsum...”) =>




Example: randomExpansion("ABC") =>





Step 2: expandText(byte[] text)



expandText() =>




expandedText = "0D3F531C61113D283F2E08183C2D0070492A2E471F4E021E23411B542F3D5718155D031D076C5910195B1D03124F6508610461..."


Step 3: scrambleText(string text, string key)




scrambleText(“0D3F531C61113D283F2E08183C2D0070492A2E471F4E02...”, “passphrase”) =>



Step 3,5: genKeyPos(int nPos, string key)



genKeyPos(468, “passphrase”) =>


Step 4: hashum(string sWord, int iTextLength)



hashum(expandText( “passphrase” ), textLen) =>




Variable Length HASH = "CYFTTNTUWNYFOCUGEETARLTWOWJHLANIVHIJFVDCPKMXETLWJYKHCEAVWDKQSDFKVVEUMPDYPGDIBBWX...."

 

Step 5: char RotCharUp(int value, char lBound, char rBound)



Final: Rotating chars

Now we have a pseudorandom, expanded and shuffled text and an Hash of the same length (468 bytes): we can rotate them!


Example:

  1. Rotate UP('A' + 'X' in the range A-Z) => 'S'

  2. Rotate DOWN('S' - 'X' in the range A-Z) => we should get: 'A'

 



We get: 'A'! Everything works!!!
