Class CryptoMain

java.lang.Object

com.hissenit.crypto.CryptoMain

public class CryptoMain
extends java.lang.Object

This class holds the version information of the library and includes all cryptographic default settings.

All settings can also be set individually in the respective classes. These crypto parameters are always stored in the libraries respective compact format, hence changing (default or individual) settings in future versions of your app based on this library does not interfere with previously stored keys or encrypted data.

For instance, you could argue that administrator account passwords should be hashed with a larger salt or iteration count, accepting a performance impact but only for specific admin accounts not the whole user database. Such a scenario can be easily built using CrococryptLib.
