[Opensource] Strong Encryption

[Will]

Hello,

I've a couple questions about the
com.jcorporate.expresso.core.security.strongencryption.StringEncryption
class.

1. org.bouncycastle.jce.provider.BouncyCastleProvider() is hardcoded in
this class. Is this the only provider supported by Expresso?
2. Why was cryptix.jce.provider.CryptixCrypto() replaced?
3. Is the Rijndael still the recommend algorithm?
4. What is the max length of the cryptoKey? Will a 400 character key be
any better then a 100 character key?

Thanks for your time,
Will
