The javax.xml.crypto and javax.xml.crypto.dsig packages are not available in Android (as of version 2.3). Therefore, standard Java API does not work. But you can use the Apache Santuario library to do that. Here are the steps: Download the xml security source distribution (curently version 1.4.4). Build with ant. Create your own library jar (only the apache classes, no javax): jar -cf xmlsec-1.4.4.jar -C build/classes org Copy xmlsec-1.4.4.jar to the libs directory of your Android project. Here's the Java code: import java.io.*; import javax.xml.parsers.*; ...

Key points: Java String.matches() matches the entire string, not a partial string. Use java.util.regex.Matcher.find() to match a partial String. For case insensitive match, use Pattern.compile with case insensitive flags: // Case insensitive for ASCII Pattern p = P... Use (?i) or (?iu) (for unicode) to inline case-insensitive flag: boolean b = "StringToMatchAgainst".matches("(?... Test code: import java.util.regex.*; public class Test...

From http://hardware.slashdot.org/story/10/09/17/0247246/HDCP-Master-Key-Is-Legitimate-Blu-ray-Is-Cracked : MakeMKV rips most Blu-Rays very easily. If you want to re-encode with compression like x264, Handbrake will do it easily (though it takes about 6 hours at "20" quality on my i7 HTPC). The audio is a little tricky, but with MKVmerge you can just take the stream that MakeMKV gave you and mux it into the video stream Handbrake spat out. Subtitles are tougher because of the way they're done on Blu-Ray, but I find that opensubtitles.org usually has a perfectly-timed SRT file for my rips, most often from a guy called Shoocat. With newer codecs, the text is super-smooth and often looks better than the subtitles on the blu-ray. The only really hellacious problem I've had with moving my Blu-Ray...

Parsing XML in Java is really simple: import java.io.*; import javax.xml.parsers.Docu... The parser implementation details are hidden behind the JAXP API. In case you want to know which parser implementation is used, this is what the JavaDoc for DocumentBuilderFactory.newInstance says: Use the javax.xml.parsers.DocumentBuilderFactory system property. Use the properties file " lib/jaxp.properties " in the JRE directory. This configuration file is in standard java.util.Properties format and contains the fully qualified name of the implementation class with the key being the system property defined above. The jaxp.properties file is read only once by the JAXP implementation and it's values are then cached for future use. If the file does not exist when the first attempt is made to read from it, no further attempts are made to...

This XML signature validator comes from the Apache XML Security project. It validates the signature according to the core validation processing rules . It does not verify that the key used to generate the signature is a trusted key. You can override the KeySelector class to make sure that the signing key is from a trusted store. import javax.xml.crypto.*; import javax.xml.cry...

Java SE 6 contains built-in utilities to generate XML signatures. This is an example that generates XML signatures using a Java keystore. It has options to generate signature for the whole document, for an element with a specific ID, or for elements matched by an XPATH expression. The XML document used to test is taken from Getting Started with XML Security : <?xml version="1.0"?> <PatientRecord> ... This is the Java code: import java.io.FileInputStream; import java.io.... However, it looks like the XPATH transform is not working. The digest generated with XPATH filter is exactly the same as that without it (i.e., the whole document)!
