Emoji, Emoji, What for Art Thou? Lisa Lebduska By providing a history and context for emojis, this essay argues that they are more a means of creative graphic expression than a threat to alphabetic literacy, and that their study contributes to a re-materilaizing of literacy. The essay acknowledges that in some instances emojis do help to clarify the intent or tone of alphabetic writing, but emojis, like alphabetic writing, are culturally and contextually bound.
To begin, it will perhaps be most helpful if you have a generic idea of the process before we get into the actual details. That way when you see the individual steps of the process you will have a better point of reference.
The basic process just a summary, we'll move on to details in a moment is this: Firefox the browser gets certificates from Comodo a Certificate Authority or CA for short but installs them into Firefox. Seamonkey Firefox is a stripped down version of Seamonkey This is not practical for our purposes.
We need the certificate to be used in Mozilla Thunderbird, not in Firefox or Seamonkey. At the same time, Thunderbird cannot retrieve the certificates we need from Comodo by itself.
So in summary, what we are doing is: Comodo the CA generates certificates for digital signatures and encryption of email CA sends a link via email in order for the end user to retrieve their certificates Browser gets the certificates from CA Browser installs the certificates to itself User asks browser to export certificates to user's computer User imports certificates into Thunderbird At this point, you might be scratching your head about the fourth step.
Why must the browser install the certificates to itself? Would it not be easier and simpler to simply download the certificates to the user's desktop and give the user instructions on the process for installing the certificates to the email program?
The answer is unfortunately, 'no'. By installing your certificates into an email program by the way, Thunderbird is not the only email client out there which can accept digital certificatesyou are using certificates for a new and specific purpose.
However, your browser has been using certificates ever since the day you installed it.
Every time that you visit a secure website, everything from eBay to Paypal and your online bank, in fact every time you see a lock icon on the address bar, you are visiting a site which has a certificate of some sort. The next time that you visit such a site, roll your mouse over the globe or lock icon and you will see a reference to Comodo, Verisign, Thawte, or other CAs.
This indicates that both the site you are visiting and your browser have a certificate that they can agree is secure and can use to protect your online transaction. The point is that your browser already uses certificates, and not only does it use them, it does so without any user interaction.
Imagine if the opposite were true. Instead of signing into your bank or shopping site, what if you had to manually approve or install a certificate to do so every time? Instead, your browser does what it is programmed to do, that is, it imports a certificate when you direct it to one.
This not only simplifies dealing with certificates in the long run, but also assures that your certificate is delivered to you in a secure manner.
Another way to put it is that it your retrieval of an email certificate is the unusual or out of scope transaction in the operation we are looking at; your browser is doing what comes naturally for the handling of certificates.
I should also add a disclaimer at this point that Comodo is not the only CA out there, and I am not necessarily advocating them as a CA above any of the others. In fact, it is also possible to generate your own keys as your own certificate authority, however such a process is advanced, will cause difficulty with other users being able to use your keys, and is well beyond the scope of this article.
For our purposes, if we can find a trusted certificate authority which will generate a certificate which both ourselves and our correspondents can use quickly and easily, and does not charge us for the privilege, let's use that one.
First start with Comodo. Comodo which will generate a certificate for your email address which lasts one year. Note that you want to permanently keep these certificates wherever you keep data files safe, even after they expire.
This is important because if you ever have to reinstall Thunderbird or move to a new computer you will not be able to read saved email encrypted with the old certificates if they are not incorporated in the new installation.
As a general rule you do not want to ever delete a certificate in the sense that it is lost and gone forever. Even if you should delete a certificate out of Thunderbird, or have to do so in order to resolve a program error message or limitation, make very sure that you back it up export it from Thunderbird first.
This is an important principle. Suppose that you password protect a file and burn it on to a CD. Even if you do not touch that CD for years to come, you will always have to use the password that you used for that file in order to access it.
