I came across this issue on OSX after using Homebrew to upgrade to PHP 7.0.12.

To resolve the problem I downloaded cacert.pem using WGET.

wget http://curl.haxx.se/ca/cacert.pem

I saved that file to my home directory /Users/alex/cacert.pem. Then configured my PHP.ini file to point to that cacert location.

To do this; First locate your php.ini and run the command php --ini that should produce:

$ php --ini
Configuration File (php.ini) Path: /usr/local/etc/php/7.0
Loaded Configuration File:         /usr/local/etc/php/7.0/php.ini
Scan for additional .ini files in: /usr/local/etc/php/7.0/conf.d

The INI file to edit is the one at the Loaded Configuration File location. Open that file in your editor of choice (Vim, etc) and find the setting openssl.cafile. This is probably commented out so uncomment it and insert the location of your cacert.pem.

You should then be able to run compose install, composer update, composer self-update, etc
