install SMIME Certificates

obtain free SMIME Certificates

Free certificates usable for S/MIME are available from:

Some of them are free only for personal use. It can also cost money to revoke a free certificate.

Let’s Encrypt does not currently offer S/MIME certificates. See https://community.letsencrypt.org/t/s-mime-certificates/153 for a thread explaining why you can’t use their SSL/TLS certificates for S/MIME.[edit]

To obtain certificate from an authority

Safari, Firefox and Microsoft Internet Explorer contain cryptotools capable of generating public/private keypairs. When signing up for a certificate with an authority, their website triggers your browser to create a keypair and transmit to them the public key, which is then certified. For this reason, when you return to pick up your completed certificate (typically a few minutes later), it is mandatory that you do so with the same browser on the same computer . You will otherwise not possess the private key necessary for pickup.

Be thoughtful about whether to select to “digitally sign all messages by default”. Institutional firewalls may protect their own security protocols and break your cryptographic signature, leaving your recipient with all kinds of warnings about the message being invalidly signed. As S/MIME usage is still not widespread, most people still don’t know how to interpret this. A broken signature will probably seem worse to them than receiving a message with no crypto signature at all, even though the contents are identical in both cases.

Youtube-dl – tips

Youtube-dl is a python based command line video downloader that just works. Despite its name would suggest, youtube-dl downloads more than just youtube videos, it currently supports more than 800 online video and audio sites. If you are using a desktop app or web app to download videos now, chances are it’s using youtube-dl in the back-end. You are better off using youtube-dl instead considering you get so much more power and options with it. Here are some simple tips to get you started.

Install from the source

There are multiple options to get started with installing youtube-dl, I personally recommend installing from the source simply because how frequently its database gets updated and most OS package managers are a bit late when keeping up with the updates. The best thing about youtube-dl is that it runs on all major OS as long as you have python installed.

Windows users can download latest exe file. For Linux, MacOS users:

sudo curl -L https://yt-dl.org/latest/youtube-dl -o /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl

Download using cURL to the proper application directory.
Apply proper access permission to run youtube-dl.
Always update to the latest version

Online video players are updated frequently which can often break how youtube-dl download video files from your favorite site. So, just like browser video downloading extensions, it’s a good idea to keep it up-to-date. You could make a cronjob, but I prefer to do it manually.

Updating youtube-dl is as simple as typing:

youtube-dl -U

How to Find and Remove @eaDir Directories on Synology NAS

Synology NAS @eaDir directories popping up everywhere. These are “hidden” folders equivalent to thumbs.db on Windows where the package stores thumbnail files associated with iTunes support. If you’re not using iTunes you don’t need these directories. You can remove them in two steps.

In SSH use the following to locate them:

cd /
find. -type d -name"@eaDir"

and if you’re feeling adventurous you can automatically delete them like so:

find . -type d -name "@eaDir" -print0 | xargs -0 rm -rf
