> In order to configure our dataSource without requiring a plaintext password in the configuration file, we extended JdbcDataSource to create our own custom implementation. Our dataSource config now looks something like this:
> {code:xml}
> <dataSource type="com.foo.FooDataSource" driver="oracle.jdbc.OracleDriver" url="jdbc:oracle:thin:@db-host-machine:1521:tst1" user="testuser" password="{ENC}{1.1}1ePOfWcbOIU056gKiLTrLw=="/>
> {code}
> We are using the RSA JSAFE Crypto-J libraries for encrypting/decrypting the password. However, this seems to cause an issue when we try use Solr in a Cloud Configuration (using Zookeeper). The error is "Strong key gen and multiprime gen require at least 1024-bit keysize." Full log attached.
> This seems to be due to the hard-coded value of 512 in the org.apache.solr.util.CryptoKeys$RSAKeyPair class:
> {code:java}
> public RSAKeyPair() {
>   KeyPairGenerator keyGen = null;
>   try {
>     keyGen = KeyPairGenerator.getInstance("RSA");
>   } catch (NoSuchAlgorithmException e) {
>     throw new SolrException(SolrException.ErrorCode.SERVER_ERROR, e);
>   }
>   keyGen.initialize(512);
> {code}
> I pulled down the Solr code, changed the hard-coded value to 1024, rebuilt it, and now everything seems to work great.
