• This error has been confirmed by @erichomanchuk, @RDeuzeman, @FlorentTorregrosa.
• This code used to work.
• More detail is available in the related comment above, but this seems to be the heart of the issue.

Hello,

There is a misunderstanding.

I have confirmed that the above code in composer.json file worked for me. But as I don't use it anymore due to new versions of the plugin, I can't confirm it does not work anymore for this particular version.

@FlorentTorregrosa: it seems that the code which you had working at one point no longer works. That is the issue here.

I can also comfirm I'm seeing this problem with ckeditor/fakeobjects (4.7.3), ckeditor/image (4.7.3) and ckeditor/link (4.6.2).

Oddly, if I go to the dist urls I am able to download the zip files without any problems, for instance ckeditor/fakeobjects:4.7.3. This makes me think that this could be a composer issue at its heart.

If I store the library locally, as in "url": "/Users/<user>/Downloads/fakeobjects_4.7.3.zip" I am able to install it with composer.

I'm using the following version of composer.

$ composer --version
Composer version 1.5.2 2017-09-11 16:59:25

After updating my composer to version 1.5.5 I got a detailed error when trying to install.

  [Composer\Downloader\TransportException]                                     
  The "https://ckeditor.com/cke4/sites/default/files/colorbutton/releases/col  
  orbutton_4.6.2.zip" file could not be downloaded: SSL operation failed with  
   code 1. OpenSSL Error messages:                                             
  error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify   
  failed                                                                       
  Failed to enable crypto                                                      
  failed to open stream: operation failed 

So the problem is a wrong or missing ssl certificate.

Printing the certificate locations in PHP showed me the following settings.

php -r 'print_r(openssl_get_cert_locations());'
Array
(
    [default_cert_file] => /usr/local/etc/openssl/cert.pem
    [default_cert_file_env] => SSL_CERT_FILE
    [default_cert_dir] => /usr/local/etc/openssl/certs
    [default_cert_dir_env] => SSL_CERT_DIR
    [default_private_dir] => /usr/local/etc/openssl/private
    [default_default_cert_area] => /usr/local/etc/openssl
    [ini_cafile] => 
    [ini_capath] => 
)

After setting ini_cafile in php.ini to the location of the cert.pem file (same setting as default_cert_file) the error is gone and composer can download the plugins.

My config after the change.

php -r 'print_r(openssl_get_cert_locations());'
Array
(
    [default_cert_file] => /usr/local/etc/openssl/cert.pem
    [default_cert_file_env] => SSL_CERT_FILE
    [default_cert_dir] => /usr/local/etc/openssl/certs
    [default_cert_dir_env] => SSL_CERT_DIR
    [default_private_dir] => /usr/local/etc/openssl/private
    [default_default_cert_area] => /usr/local/etc/openssl
    [ini_cafile] => /usr/local/etc/openssl/cert.pem
    [ini_capath] => 
)

Thanks @RDeuzeman, the steps above fixed this issue for me.

Interesting. That is not the original error I received, and I was on composer 1.5.5. I attempted your fix, but am still getting this new SSL error. Any suggestions?

I dug around a bit and had to download more recent certs: https://stackoverflow.com/questions/28283789/cannot-establish-ssl-connection-with-composer-with-php-5-6-3?answertab=votes#tab-top
