Signature mismatch, could not verify the phar file integrity

This has been running on my computer for a few years and I have been able to do self-updates regularly in the past.

When I run curl -sS http://getcomposer.org/installer | php, I get:

PHP Warning:  openssl_verify(): supplied key param cannot be coerced into a public key in - on line 576
PHP Warning:  openssl_free_key() expects parameter 1 to be resource, boolean given in - on line 577
Signature mismatch, could not verify the phar file integrity

As I workaround for my dev env, I used curl -sS http://getcomposer.org/installer | php -- --disable-tls.
