Mirabox notes

THE LOCATION OF THIS PAGE HAS MOVED!

The new location is https://github.com/psanford/mirabox. I've turned it into a full git repository so that it is easier for others to contribute. This gist will not be updated anymore and I won't be checking the comments. Please open an issue or a pull request on the git repo.

OLD CONTENT:

There's not a lot of good documentation about Globalscale Technology's [Mirabox][1] so this page is intended to document everything I know about it. My goal is to run a modern kernel and bootloader on the Mirabox.

How to convert a .pfx SSL certificate to .crt/key (pem) formats. Useful for NGINX
source: http://www.markbrilman.nl/2011/08/howto-convert-a-pfx-to-a-seperate-key-crt-file/
`openssl pkcs12 -in [yourfile.pfx] -nocerts -out [keyfile-encrypted.key]`
What this command does is extract the private key from the .pfx file. Once entered you need to type in the importpassword of the .pfx file. This is the password that you used to protect your keypair when you created your .pfx file. If you cannot remember it anymore you can just throw your .pfx file away, cause you won’t be able to import it again, anywhere!. Once you entered the import password OpenSSL requests you to type in another password, twice!. This new password will protect your .key file.
Now let’s extract the certificate:
`openssl pkcs12 -in [yourfile.pfx] -clcerts -nokeys -out [certificate.crt]`
