SSL encryption

PHP Driver supports SSL encryption.

Connecting without SSL encryption

Given

a running Cassandra cluster with SSL encryption

And

the following example:

$cluster = Dse::cluster()->build();

try {
    $session = $cluster->connect();
} catch (Dse\Exception\RuntimeException $e) {
    echo "Connection failure" . PHP_EOL;
}

When

it is executed

Then

its output should contain:

Connection failure

Connecting with basic SSL encryption

Given

a running Cassandra cluster with SSL encryption

And

the following example:

$ssl     = Dse::ssl()
               ->withVerifyFlags(Dse::VERIFY_NONE)
               ->build();
$cluster = Dse::cluster()
               ->withSSL($ssl)
               ->build();

try {
    $session = $cluster->connect();
    echo "Connection success" . PHP_EOL;
} catch (Dse\Exception\RuntimeException $e) {
    echo "Connection failure" . PHP_EOL;
}

When

it is executed

Then

its output should contain:

Connection success

Connecting with certificate verification

Given

a running Cassandra cluster with SSL encryption

And

the following example:

$ssl     = Dse::ssl()
               ->withVerifyFlags(Dse::VERIFY_PEER_CERT)
               ->withTrustedCerts($_SERVER['SERVER_CERT'])
               ->build();
$cluster = Dse::cluster()
               ->withSSL($ssl)
               ->build();

try {
    $session = $cluster->connect();
    echo "Connection success" . PHP_EOL;
} catch (Dse\Exception\RuntimeException $e) {
    echo "Connection failure" . PHP_EOL;
}

When

it is executed with proper SSL credentials

Then

its output should contain:

Connection success

Connecting with client certificate verification

Given

a running Cassandra cluster with SSL encryption and client authentication

And

the following example:

$ssl     = Dse::ssl()
               ->withVerifyFlags(Dse::VERIFY_PEER_CERT)
               ->withTrustedCerts($_SERVER['SERVER_CERT'])
               ->withClientCert($_SERVER['CLIENT_CERT'])
               ->withPrivateKey($_SERVER['PRIVATE_KEY'], $_SERVER['PASSPHRASE'])
               ->build();
$cluster = Dse::cluster()
               ->withSSL($ssl)
               ->build();

try {
    $session = $cluster->connect();
    echo "Connection success" . PHP_EOL;
} catch (Dse\Exception\RuntimeException $e) {
    echo "Connection failure" . PHP_EOL;
}

When

it is executed with proper SSL credentials

Then

its output should contain:

Connection success
