Just noticed we’ve got two alike tags:

  • Multiple encryption means encrypting a message two or more times using either the same, or a different algorithm.

  • Double encryption is the process of encrypting a message multiple times, either using the same or a different algorithm.

Both practically describe the same.

Because “double encryption” seems to be one of many forms of “multiple encryption”, I would like to suggest making a tag synonym of .

As you’ll notice, is merely used by this question. Meaning: we could also simply replace that double-encryption tag and let the tag fade out, but chances are that someone else will come along and use that tag again… so I guess making it a synonym of the multi-encryption tag could be the smarter move. What do you think?

    $\begingroup$ Well, arguably the tag excerpt is wrong, since double encryption means.. double encryption. As in 'twice'. But I agree, double-encryption is too specific as a tag IMHO. $\endgroup$

  • $\begingroup$ @Thomas Yep, that tag description isn’t the best. Whatever… the way I interpret things is that double-encryption is indeed encrypting it twice – aka “more than once”, which would also make it fit the multiple-encryption tag from the more-than-once perspective. Yet, I’m not saying I’m seeing things correctly in this case, that’s why I’ve thrown it in here for discussion. ;) $\endgroup$

  • $\begingroup$ What's wrong if both of the tags exist? Does same meaning tags create any problem? $\endgroup$

  • $\begingroup$ @Giliweed There’s no actual “problem”. It’s more of a keeping-things-clean thing, as double-encryption is somewhat redundant due to the existence of multiple-encryption. $\endgroup$

I removed from the one in question. If it ends up popping up again in the future, we can consider blacklisting it.
