It's Monday morning. Fernando just sat down at his desk for another hard day at work - programming stuff and answering telephone calls - "have you tried turning it off and on again?"

As he is about to login onto his machine he notices a tiny bit of yellow paper sticking out from underneath the keyboard. He moves the keyboard away to find a sticky note with the following text on it:

51577830494373674D773D3D

He is not quite sure what to make of it, but he thinks that the new intern, Ganna, left it for him. The previous night the two were out on a date. He took her to this fancy restaurant and they seemed to have a really good time together. However when they had almost finished eating, she received a call and after a brief moment she said she had an urgent matter to attend to - promptly leaving without offering any explanation.

This made him think that she didn't actually enjoy the date at all - so he didn't quite bother call her afterwards.

Hints:

#1 (Obvious): Ganna is also a WINDOWS software developer. [Thanks for pointing out guys]

    $\begingroup$ Clearly not a very good engineer then. The message is blantantly longer than the information she wishes to convey. $\endgroup$ – Neil Nov 21 '14 at 11:18

    $\begingroup$ I think saying "Have you ever met a woman" proves he has a sense of humour. Calm down :) $\endgroup$ – Jimmery Nov 21 '14 at 13:58

    $\begingroup$ Taking your own intern out on a date is a bloody stupid idea. $\endgroup$ – Lightness Races in Orbit Nov 21 '14 at 18:45

Three steps:

Since there is no higher letter than F we can assume it is Hex code, if we convert it to ASCII: QWx0ICsgMw==

This looks like

a base64-encoded string. If we decode that: Alt + 3

Which gives us the following result when used in a web browser:

    $\begingroup$ Where does Alt+3 create a heart symbol? $\endgroup$ – hexafraction Nov 21 '14 at 11:38

    $\begingroup$ Generally you use the numpad for alt codes. Alt + Numpad 3 would probably be a bit more appropriate, but it wouldn't be a puzzle without some details being implicit. $\endgroup$ – zzzzBov Nov 21 '14 at 14:55

    $\begingroup$ Alt+(Numpad)3 works on Windows. So Ganna is a windows developer, which explains why she prefers long, convoluted, cryptic stuff over short and readable code. $\endgroup$ – Guntram Blohm Nov 21 '14 at 16:35
