Project web

URL: http://totpme.sourceforge.net

Development

You can simply build the software yourself.

How to get the sources

You should have git installed

git clone git://github.com/kwart/totp-me.git

or you can download current sources as a zip file

How to build it

Install Maven.

Download lcrypto-j2me-xxx archive ("xxx" - current version of lcrypto, for example "lcrypto-j2me-160.tar.gz") from the Bouncy Castle website, extract it and install the classes as a JAR file to your local repository:

wget https://www.bouncycastle.org/download/lcrypto-j2me-160.tar.gz
tar xf ./lcrypto-j2me-160.tar.gz
mvn install:install-file -Dfile=lcrypto-j2me-160/zips/cldc_bccore_classes.zip -DgroupId=org.bouncycastle -DartifactId=lcrypto-j2me -Dversion=1.60 -Dpackaging=jar

Build the totp-me and feed it with lcrypto version from the previous step:

mvn clean package -Dlcrypto.version=1.60

This default build uses Microemulator API implementation to simplify the build process, but it's only MIDP-2.0 implementation. To be sure the source code is MIDP-1.0 compatible, you should install Oracle WTK and provide path to it to Maven as wtk.home system property

mvn clean package -Dwtk.home=/opt/WTK2.5.2

How to run it in the Microemulator

Just use exec:java goal after you've successfully built the project (provide lcrypto version if needed).

mvn exec:java -Dlcrypto.version=1.60
