I know that OpenSSL extension is in PHP source, but I can't enable it when I perform apt-get install php5. There is not even a apt-get install php5-openssl. How I must proceed?

I think SSL support doesn't depend on an extension, it's already built into Ubuntu's PHP. Try creating a PHP file in your web server with this content:
<?php phpinfo() ?> then access it in a browser (). You should see:

and

I have only these PHP packages installed: libapache2-mod-php5, php5-cli, php5-common, php5-gd, php5-mcrypt, php5-mysql.
3Try:
php -i | grep -i openssl If you have the OpenSSL extension installed, you should see something like this:
openssl OpenSSL support => enabled OpenSSL Library Version => OpenSSL 1.0.1f 6 Jan 2014 OpenSSL Header Version => OpenSSL 1.0.1f 6 Jan 2014 openssl.cafile => no value => no value openssl.capath => no value => no value OpenSSL support => enabled It seems that the OpenSSL extension is installed by default.
Update:
If you don't have this extension, you can edit php.ini file.
From php.ini:
;;;;;;;;;;;;;;;;;;;;;; ; Dynamic Extensions ; ;;;;;;;;;;;;;;;;;;;;;; ; If you wish to have an extension loaded automatically, use the following ; syntax: ; ; extension=modulename.extension ; ; For example, on Windows: ; ; extension=msql.dll ; ; ... or under UNIX: ; ; extension=msql.so ; ; ... or with a path: ; ; extension=/path/to/extension/msql.so ; ; If you only provide the name of the extension, PHP will look for it in its ; default extension directory. ; 6I installed OpenSSL 1.1.0f using
