How to switch OpenSSL version on Mac using Homebrew?

Scenario: you have both OpenSSL 1.0 and 1.1 installed (using Brew) in your OSX system and you want to switch the current active version without removing other versions that already installed. Here is how to do it.

Step 1 - List all OpenSSL versions

$ ls -al /usr/local/Cellar/openssl*

Idea from ShinyMarusu @ Reddit:

• https://www.reddit.com/r/Piracy/comments/auhyxk/how_do_i_download_from_panbaidu/eovyg8g/
• I just unintentionally discovered how to do it after searching how to create an account for day and a half. LOL hope it works for you too.
• First go to this link (baidu cloud app) to register. Use your phone number to get the verification code and enter. For the rest, use google to translate the page and put your email adress, name, etc. and you're good to go. This method logs you to the cloud directly so you just step over the problematic pan,baidu registration which rejects non-chinese phone numbers for some reason. After registering I refreshed the page of the file I was trying to download and it showed me as already logged in, then I FINALLY could download the mod. It's sad this method isn't listed anywhere, I really searched a lot... Anyways, good luck!

More notes:

• It's a pain in the rear. It took me an hour, but at least it worked.
• Get an Chinese email. You will use it as yo

Place file into qemu root directory Do cd path/to/qemu && ./name_of_file name_of_target (i.e. x86_64-softmmu) Library is at /path/to/qemu/x86_64-softmmu/libqemu.so You might need to compile vl.c and link with it in your final binary, just do something like this:

#define main __definetly_not_main
#include "/path/to/qemu/vl.c"
#undef main

import struct

# returns encoded dict
# this function assumes data in a particular format: it contains an array of field and values.
# each field is represented as a tuple of size 4 (value, wire type, field number, if field is an array)
# eg. message Msg { int64 id = 1; string text = 2; } => [[1234, 'varint', 1, False], ['hello world', 'string', 1, False]]
# also we can assume that every protobuf message is a dict at start, so this function is an entry point for encoding.
