h4siaizP2foaa/PiVeJmyVhKaGdO0v1+caaaaa==


I think a simple greeting would be too boring and banal, so I made an encrypted one The cyphering may look obvious, but don't jump to conclusions so fast.

Greetings bodqhrohro. What does your username and "h4siaizP2foaa/PiVeJmyVhKaGdO0v1+caaaaa==" mean?

My nickname is described here. In short, this is a diminutive form of my name followed with the onomatopoeia of pig grunt in Ukrainian, both written in Cyrillic and encoded in KOI-7.

Determining what does the title means is a challenge If it would turn up too hard, I will offer some hints.

Okay, still no any guesses, so here's my first hint. To decode this, the short pipeline of usual UNIX utilities is enough. Guess what Good luck!

Sorry bodqhrohro, I'm too busy to work out the meaning.

Okay, if still no one have guessed it, I'm uncovering the answer:

echo 'h4siaizP2foaa/PiVeJmyVhKaGdO0v1+caaaaa=='|tr A-Ma-m a-mA-M|base64 -d|gunzip

Luckily, it wasn't hard to recall it after almost a year

That's a lot of work to just get 'Hi all!'.

The double == is a dead giveaway that is is base64 encoded. FYI, base64 is not encryption but encoding Encryption requires a key to decrypt, encoding does not.

Welcome by the way!

I just guessed: "tr A-Ma-m a-mA-M" is your key

So although I suppose technically that is encryption, I wouldn't use it to protect my financial info. Clever though!

That's why I told it may look obvious. But it's not that simple.

Whaouh not very simple...
I'm wondering how one could tell about the "tr A-Ma-m a-mA-M" part... Was there any hint about it?
https://en.wikipedia.org/wiki/List_of_file_signatures can help regarding the gunzip part
