§Configuring Certificate Revocation

Certificate Revocation in JSSE can be done through two means: certificate revocation lists (CRLs) and OCSP.

Certificate Revocation can be very useful in situations where a server’s private keys are compromised, as in the case of Heartbleed.

Certificate Revocation is disabled by default in JSSE. It is defined in two places:

To enable OCSP, you must set the following system properties on the command line:

java -Dcom.sun.security.enableCRLDP=true -Dcom.sun.net.ssl.checkRevocation=true

After doing the above, you can enable certificate revocation in the client:

play.ws.ssl.checkRevocation = true

Setting checkRevocation will set the internal ocsp.enable security property automatically:

java.security.Security.setProperty("ocsp.enable", "true")

And this will set OCSP checking when making HTTPS requests.

Note: Enabling OCSP requires a round trip to the OCSP responder. This adds a notable overhead on HTTPS calls, and can make calls up to 33% slower. The mitigation technique, OCSP stapling, is not supported in JSSE.

Or, if you wish to use a static CRL list, you can define a list of URLs:

play.ws.ssl.revocationLists = [ "http://example.com/crl" ]

§Debugging

To test certificate revocation is enabled, set the following options:

play.ws.ssl.debug = {
 certpath = true
 ocsp = true
}

And you should see something like the following output:

certpath: -Using checker7 ... [sun.security.provider.certpath.RevocationChecker]
certpath: connecting to OCSP service at: http://gtssl2-ocsp.geotrust.com
certpath: OCSP response status: SUCCESSFUL
certpath: OCSP response type: basic
certpath: Responder's name: CN=GeoTrust SSL CA - G2 OCSP Responder, O=GeoTrust Inc., C=US
