1 OpenSSL on the Android platform. 2 --- 3 4 The code in this directory is based on $OPENSSL_VERSION in the file 5 openssl.version. See patches/README for more information on how the 6 code differs from $OPENSSL_VERSION. 7 8 Porting New Versions of OpenSSL. 9 -- 10 11 The following steps are recommended for porting new OpenSSL versions. 12 13 1) Retrieve the appropriate version of the OpenSSL source from 14 www.openssl.org/source (in openssl-*.tar.gz file). Check the PGP 15 signature (found in matching openssl-*.tar.gz.asc file) with: 16 17 gpg openssl-*.tar.gz.asc 18 19 If the public key is not found, import the the one with the 20 matching RSA key ID from http://www.openssl.org/about/, using: 21 22 gpg --import # paste PGP public key block on stdin 23 24 2) Update the variables in openssl.config and openssl.version as appropriate. 25 At the very least you will need to update the openssl.version. 26 27 3) Run: 28 29 ./import_openssl.sh import openssl-*.tar.gz 30 31 4) If there are any errors, then modify openssl.config, openssl.version 32 and patches in patches/ as appropriate. You might want to use: 33 34 ./import_openssl.sh regenerate patches/*.patch 35 36 Repeat step 3. 37 38 5) Cleanup before building with: 39 40 m -j16 clean-libcrypto clean-libssl clean-openssl clean-ssltest 41 42 6) Build openssl from the external/openssl directory with: 43 44 mm -j16 snod && adb remount && adb sync system 45 46 If there are build errors, then patches/*.mk, openssl.config, or 47 android-config.mk may need updating. 48 49 7) Run tests to make sure things are working: 50 51 # Run local openssl tests 52 (cd android.testssl/ && ./testssl.sh) 53 # Build and sync libcore tests 54 (croot && cd libcore && mm -j16 snod && adb remount && adb sync) 55 # Run tests from libcore 56 (croot && vogar --classpath out/target/common/obj/JAVA_LIBRARIES/core-tests_intermediates/classes.jar javax.net.ssl tests.api.javax.net) 57 # Run tests from Harmony 58 (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) 59 # try an https website 60 adb shell am start https://online.citibank.com # confirm result in browser 61 62 The vogar tool can be found externally at http://code.google.com/p/vogar/ 63 64 Quick installation instructions (without rebuilding from source): 65 VOGAR=$HOME/vogar 66 svn co http://vogar.googlecode.com/svn/trunk/ $VOGAR 67 mkdir -p $VOGAR/build/ 68 curl -o $VOGAR/build/vogar.jar https://vogar.googlecode.com/files/vogar.jar 69 PATH=$PATH:$VOGAR/bin 70 71 Within Google, you can find it under: 72 /home/dalvik-prebuild/vogar/bin/vogar 73 74 # You can also run openssl s_server as a test server on the device: 75 adb push ./android.testssl/CAss.cnf /sdcard/CAss.cnf 76 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 77 adb shell openssl s_server -cert /sdcard/server.pem -www -verify 1 78 adb shell am start https://localhost:4433 # confirm result in browser 79 80 8) Do a full build before checking in: 81 82 m -j16 83 84 Optionally, check whether build flags (located in CONFIGURE_ARGS in 85 openssl.config, plus some extras in android-config.mk), need to be updated. 86 Doing this step will help ensure that the compiled library is appropriately 87 optimized for speed and size. 88
