How to open a Base64 encrypted 7z File on Windows?

Question

As the title already describes, I have a text file with base64-code which was originally a password protection *.7z file.

How do I proceed correctly to get the content from this file, under Windows?

---

My attempt so far was

1. Decode Content of Text File in ASCII (with a simple Python 2.7 Script)

2. Save Output as *.7z

3. Try to open this File with 7-Zip

But that did not work. If i try to open the file 7-Zip tells me, "{Target File} is no Archive".

Answer 1

You can use

certutil -decode base64encoded.7z decoded.7z

and then open the 7z file in 7Zip, enter the password etc. as usual.
