How to resolve SSLProtocol Syntax Error

H. Ferrence asked:

I am trying to install an SSL Certificate.

When I restart apache I get this error:

SSLProtocol: Illegal protocol ‘\xe2\x80\x93SSLv2’

Here are my conf file directives:

<VirtualHost *:443>
    ServerAlias *
    DocumentRoot /home/abc/public_html/
    SSLEngine on
    SSLProtocol all -SSLv2 -SSLv3
    SSLCertificateFile /etc/ssl/mycert_example_com_cert.cer
    SSLCertificateKeyFile /etc/ssl/mycert.key
    SSLCACertificateFile /etc/ssl/mycert_example_com_interm.cer
    ErrorLog logs/sites_error_log
    CustomLog logs/sites_access_log common

My answer:

Your configuration line doesn’t contain the expected hyphen (-). It instead contains an en dash (). It looks similar, but it’s a completely different character.

In fact, it appears both of them are en dashes.

This can happen if you copy and paste from a web site which has unhelpfully changed hyphens to en dashes.

To solve the problem, replace both of the en dashes with hyphens.
