OpenSSL on the Android platform. --- The code in this directory is based on $OPENSSL_VERSION in the file openssl.version. See patches/README for more information on how the code differs from $OPENSSL_VERSION. Porting New Versions of OpenSSL. -- The following steps are recommended for porting new OpenSSL versions. 1) Retrieve the appropriate version of the OpenSSL source from www.openssl.org/source (in openssl-*.tar.gz file). Check the PGP signature (found in matching openssl-*.tar.gz.asc file) with: gpg openssl-*.tar.gz.asc If the public key is not found, import the the one with the matching RSA key ID from http://www.openssl.org/about/, using: gpg --import # paste PGP public key block on stdin 2) Update the variables in openssl.config and openssl.version as appropriate. At the very least you will need to update the openssl.version. 3) Run: ./import_openssl.sh import openssl-*.tar.gz 4) If there are any errors, then modify openssl.config, openssl.version and patches in patches/ as appropriate. You might want to use: ./import_openssl.sh regenerate patches/*.patch Repeat step 3. 5) Cleanup before building with: m -j16 clean-libcrypto clean-libssl clean-openssl clean-ssltest 6) Build openssl from the external/openssl directory with: mm -j16 snod && adb remount && adb sync system If there are build errors, then patches/*.mk, openssl.config, or android-config.mk may need updating. 7) Run tests to make sure things are working: # Run local openssl tests (cd android.testssl/ && ./testssl.sh) # Build and sync libcore tests (croot && cd libcore && mm -j16 snod && adb remount && adb sync) # Run tests from libcore (croot && vogar --classpath out/target/common/obj/JAVA_LIBRARIES/core-tests_intermediates/classes.jar javax.net.ssl tests.api.javax.net) # Run tests from Harmony (croot && vogar --classpath out/target/common/obj/JAVA_LIBRARIES/apache-harmony-tests_intermediates/classes.jar tests.api.java.math.BigIntegerTest org.apache.harmony.tests.java.math) # try an https website adb shell am start https://online.citibank.com # confirm result in browser The vogar tool can be found externally at http://code.google.com/p/vogar/ Quick installation instructions (without rebuilding from source): VOGAR=$HOME/vogar svn co http://vogar.googlecode.com/svn/trunk/ $VOGAR mkdir -p $VOGAR/build/ curl -o $VOGAR/build/vogar.jar https://vogar.googlecode.com/files/vogar.jar PATH=$PATH:$VOGAR/bin Within Google, you can find it under: /home/dalvik-prebuild/vogar/bin/vogar # You can also run openssl s_server as a test server on the device: adb push ./android.testssl/CAss.cnf /sdcard/CAss.cnf adb shell openssl req -config /sdcard/CAss.cnf -x509 -nodes -days 365 -subj '/C=US/ST=California/L=Mountain View/CN=localhost' -newkey rsa:1024 -keyout /sdcard/server.pem -out /sdcard/server.pem adb shell openssl s_server -cert /sdcard/server.pem -www -verify 1 adb shell am start https://localhost:4433 # confirm result in browser 8) Do a full build before checking in: m -j16 Optionally, check whether build flags (located in CONFIGURE_ARGS in openssl.config, plus some extras in android-config.mk), need to be updated. Doing this step will help ensure that the compiled library is appropriately optimized for speed and size.
