Host base64 encoded file on Google Blogger page body

It is possible to host base64 encoded information on Blogger page body. For example I publish a page with base64 encoded information:spacewalk-2.8-install-centos-7.5.sh

And now it is possible to decode back this file on Linux with:

curl -s "https://catonrug.blogspot.com/feeds/posts/default/7187828752353625240?alt=json" | jq -r '.entry|.content|."$t"' | base64 --decode > ~/spacewalk-2.7-install-centos-7.4.sh

On Windows using additional libraries:

Execute:

curl -s "https://catonrug.blogspot.com/feeds/posts/default/7187828752353625240?alt=json" | jq -r ".entry|.content|.\"$t\"" > spacewalk-2.7-install-centos-7.4.base64
certutil -decode spacewalk-2.7-install-centos-7.4.base64 spacewalk-2.7-install-centos-7.4.sh
