cipher - Crack the code: JavaRelated


I got a card with a text from a software company, and it tells me to decode it.
The only thing written on the card is the following code:


  bWpvey9vam9rYjMxMjZBZXpvYnVzYmRmL2Rwbg==

Might be Java related



Answer




The string is base 64 encoded, decoding gives:


  mjo{/ojokb3126Aezobusbdf/dpn

The string /dpn gives a further clue how it needs to be deciphered; if you take the previous character in the ASCII table you get .com. Substituting each letter with the previous letter in the ASCII table gives the following email address. I have replaced @ with (at) to avoid email scrapers abusing this address.
