MOSS

The link to MOSS should be removed or disambiguated. The only reasonable disambiguation would be to Microsoft Office SharePoint Server, but that article doesn't suggest it is the appropriate target of the link. —Ksn 15:56, 28 July 2006 (UTC)[reply]

When?

First sentence says "early". Is that 2005, 1995, 1885 or sthg else? 86.185.216.121 (talk) 15:24, 24 April 2011 (UTC)[reply]

Ok, found answer. Will edit page. 86.185.216.121 (talk) 15:25, 24 April 2011 (UTC)[reply]

Usage in SSL

Aren't pem files used in apache?

Are they related? Family Guy Guy (talk) 06:47, 7 March 2012 (UTC)[reply]

I was wondering this too because the article on X.509 links here when it is talking about PEM files, which are a Base64 representation of the certificate binary data. (That's what you use in Apache HTTPD.) It seems like the PEM format may have been developed originally for the Privacy-Enhanced Mail and the usage of this file extension for Base64-encoded X.509 certificates is a legacy of that? If so this deserves a mention on the article, but I don't have a source proving this relationship. Jpp42 (talk) 12:45, 12 July 2012 (UTC)[reply]

Spelling/case confusing

The title is Privacy-enhanced Electronic Mail. It appears to be a proper noun, but should it be Privacy-enhanced electronic mail (as a common noun)? The article itself uses Privacy-enhanced Mail (without the "Electronic"). --Mortense (talk) 09:09, 28 August 2013 (UTC)[reply]

Tone flag

That one long paragraph is a soft apple, with this at the core:

This is an IETF standard, a result of a group working for a long time. The basic idea ...

Decoding examples with openssl

Use openssl req to operate on certificate requests, and -text to convert to text format:

   $ openssl req -text <<__EOF__
