BroCode

"BroCode" is a tool capable of encrypting, decrypting a-z, 0-9, string with encryption key. The encryption key is of course can be anything but only known by authorized ones. This tools mainly is to improve my python skill as well as my for my own personal uses. Below you can see how "what is goin on 123" string is encrypted with a encryption key "mykey" string.

Tip: Standalone binaries are in the bin for those in case you're not aware of.

Encryption Method

String : "what is goin on 123"

Encryption_key : mykey

Any spaces must be replace with '+' The string is split into length of blocks equal to the length of encryption_key

  what+is+goin+on+123
  what+ is+go in+on +123+

Then convert the blocks into its digital equivalent from the dictionary table. a=01, b=02, ... , z=26, +=00, 1=27,...9=35,0=36 'what+'=2308012000, 'is+go'=0919000715, 'in+on'=0914001514 '+123+'=0027282900 Proceed to convert the encryption key to its digital equivalent also mykey:1325110525

For each of the block each two digit in the block may sum with encrption_key relatively. In case the sum goes beyond 36 (which is total supported character count - 1) sum % 37 (total supported character count) = x and take the x. Then the convert the result back into it alphabetical equivalent to get encypted string.

     2308012000  0919000715  0914001514 0027282900
     1325110525  1325110525  1325110525 1325110525
     ----------  ----------  ---------- -----------
     3633122525  2207111203  2202112002 1315023425  ----> "07lyy vgklc vbktb mob8y"

The string is finally encrypted as 07lyyvgklcvbktbmob8y by encryption_key mykey
