Build Instructions for BorderCastle

Clone this repository into a local work directory, called IC_HOME in the following steps, and make it the current directory.
Download the full distribution from the BouncyCastle GitHub release page, e.g. bc-java-r1v81.zip.
Unpack the downloaded archive and rename the created folder to crypto:

    IC_HOME$ unzip bc-java-r1v81.zip
    IC_HOME$ mv bc-java-r1v81 crypto
    IC_HOME$ chmod -R u+w crypto/*

This should result in a directory structure similar to the following:

    IC_HOME$ ls -Al
    total 296260

    IC_HOME$

Execute the script to convert the project structure to maven:

    IC_HOME$ bin/bouncycastle-to-maven-layout.sh

Execute the script to perform the package renaming and other replacements:

    IC_HOME$ bin/bouncycastle-to-bordercastle.sh

Apply the patch for the chosen version to add the BorderCastle specific additions and changes:

    IC_HOME$ patch -p1 < bouncycastle/crypto-1.81.patch

Compile the libraries with Maven (assuming a version compatible with Maven 3.0.5):

    IC_HOME$ mvn clean install

If all went well, you'll find the built libraries in the target folder in each of the maven project folders, e.g.:

    IC_HOME$ find -name "*.jar"
    ./ic-light/target/ic-light-1.81.jar
    ./ic-mail/target/ic-mail-1.81.jar
    ./ic-pg/target/ic-pg-1.81.jar
    ./ic-pkix/target/ic-pkix-1.81.jar
    ./ic-prov/target/ic-prov-1.81.jar
    ./ic-test/target/ic-test-1.81.jar
    ./ic-tls/target/ic-tls-1.81.jar
    ./ic-util/target/ic-util-1.81.jar
