Using the following command to initialize a keystore, I get the following exception:

java -jar org.cumulus4j.keymanager.cli-1.0.0-SNAPSHOT.jar initDateDependentKeyStrategy -keyActivityPeriod 30s -keyStorePeriod 1y -keyStoreID test-fleque

java.lang.IllegalArgumentException: source too long! Cannot encode length 16819252 in 2 bytes!

    A faster way to reproduce this is:
    java -jar org.cumulus4j.keymanager.cli-1.0.0-SNAPSHOT.jar initDateDependentKeyStrategy -keyActivityPeriod 30s -keyStorePeriod 2d -keyStoreID test-fleque -userName fleque

    I analysed the bug and created a test case for it:

    org.cumulus4j.keystore.test.DateDependentKeyStrategyTest.initialiseWithManyKeys()

    I already implemented a solution and tested it: It works fine, but it breaks compatibility: EncryptedProperty has now the (newly introduced) overridden method 'getEncryptedDataLengthHeaderSize()'. If the result is changed from 2 to 4, it works fine, but a bigger 'length' field means that the old key-stores cannot be read anymore.

    We therefore need to increment the file version number (from 1 to 2) and implement a mechanism that allows for reading old files (they can be automatically converted to the new format, IMHO - i.e. only reading needs to take the old version into account - writing doesn't necessarily).

    Because I do not have enough time, I left the file format unchanged, for now. Need to do this later.

    There are now two supported key store file versions: 1 and 2. The KeyStore can read both and will always write version 2.
