Whoops! My example forgot to include its "getDefault()" method!
package a.b.c; public class SSL extends org.apache.commons.ssl.SSLClient { public static SSLSocketFactory getDefault() throws GeneralSecurityException, IOException { return new SSL(); } public SSL() throws GeneralSecurityException, IOException { super(); super.setCheckCRL( true ); super.setCheckHostname ( false ); super.setCheckExpiry( false ); TrustMaterial tm = new TrustMaterial( "/path/to/certs.pem" ); char[] password = "secret".toCharArray(); KeyMaterial km = new KeyMaterial( "/path/to/pkcs12.der", password ); super.setTrustMaterial( tm ); super.setKeyMaterial( km ); } } On 1/27/07, Julius Davies <[EMAIL PROTECTED]> wrote:
ps. If you are interested, here's how you provide the hook to " not-yet-commons-ssl.jar". Add a new "config property" (config file, System.getProperty(), get/set bean... however you normally do these things) to your library. The property should be something like this: "org.apache.commons.net.ssl.clientFactory" If the property is not, your library should probably just default to this: HttpsURLConnection.getDefaultSSLSocketFactory(); That's usually preferable to SSLSocketFactory.getDefault() because HttpsURLConnection's default socket factory will magically use the browser's ssl-proxy settings and client certs if Java is being run from "Webstart" or from an applet. (And, seriously, you never know where someone is going to use your library!) Anyway... back to "not-yet-commons-ssl".... Suppose the following is set: org.apache.commons.net.ssl.factory=a.b.c.SSL The contract of the "hook" is that the class specified will contain a static getDefault() method, so you can use this to get the factory: Class c = Class.forName( "a.b.c.SSL" ); Method m = c.getMethod( "getDefault", null ); SSLSocketFactory sf = (SSLSocketFactory) m.invoke( null, null ); Meanwhile, the application developer who's using your library can then do something like this to specify a particular set of TrustAnchors, Client Certificates, special validation, etc, that they know they need when using SSL in their environment. (Really handy for dealing with self-signed "dev" certs in a way that doesn't pollute every SSL socket then created anywhere in the JVM!). package a.b.c; public class SSL extends org.apache.commons.ssl.SSLClient { public SSL() throws GeneralSecurityException, IOException { super(); super.setCheckCRL( true ); super.setCheckHostname ( false ); super.setCheckExpiry( false ); TrustMaterial tm = new TrustMaterial( "/path/to/certs.pem" ); char[] password = "secret".toCharArray(); KeyMaterial km = new KeyMaterial( "/path/to/pkcs12.der", password ); super.setTrustMaterial( tm ); super.setKeyMaterial( km ); } } The nice thing about this hook: "commons-net" doesn't have to include ANY reference to "not-yet-commons-ssl". There's no compile-time dependency, and certainly no runtime dependency. The static getDefault() method is already a standard part of javax.net.ssl.SSLSocketFactory! Application developers using your library *could* specify this! org.apache.commons.net.ssl.clientFactory=javax.net.ssl.SSLSocketFactory (I guess in FTP's case, you also need to create Server-Sockets for those weird "PASSIVE" connections?... But it's all the same - just one more line of config that can be ignored since you'll safely default to " javax.net.ssl.SSLServerSocketFactory.getDefault()" anyway unless people want to get fancy with not-yet-commons-ssl's "SSLServer" class). yours, Julius http://juliusdavies.ca/commons-ssl/ On 1/27/07, Julius Davies <[EMAIL PROTECTED]> wrote: > > Hi, > > I thought I'd mention that "not-yet-commons-ssl-0.3.5" might be useful > when using FTPS: > > http://juliusdavies.ca/commons-ssl/ > > Apache has recieved my personal CLA, and my company's CCLA.
