Hash roll

Augustine's friend took a important file of augustine and stashed it.

He was able to grab all the files from his friend's machine but he is worried that the files are encrypted.

Help him get the file back

About the Challenge

We got 2 files, nothing.pdf and also encrypted1.zip (This is a zip protected password) and we need to find the password for encrypted1.zip

How to Solve?

Open the nothing.pdf first, and then tried to use CTRL + a keyboard shortcut to select all texts

pdf

You will notice there was very small text at the bottom of the PDF file. Now, press CTRL + c to copy the text and CTRL + v to paste the text into a text editor (in this case, I'm using Notepad). We got some interesting results.

Never gonna give you up
Never gonna let you down
Never gonna run around and desert you
Never gonna make you cry
Never gonna say goodbye
Never gonna tell a lie and hurt you
We've known each other for so long
Your heart's been aching, but you're too shy
to say it
29ebf2f279da44f69a35206885cd2dbc might be something you need

Afterward, I tried searching the MD5 hash on Google, and we found out that the password for the zip file is diosesamor

hash

Extract the zip file, and you will find one file called flag.jpg. Open it to obtain the flag.
