You also have support functions that help you encrypt / decrypt strings. The interface is shown bellow. // XTEA encryption and decryption function function XTeaEncryptBytes(const Data, Key: TBytes): TBytes; function XTeaDecryptBytes(const Data, [...]

Simple XML based storage – Part III.
As I promised a long time ago I have to conclude the SimpleStorage description with this final triology post. In this post I will present two very powerfull and complex mechanics behind SimpleStorage: Filters Adapters Filters Filters are a very powerful addition to SimpleStorage, that let us “filter” data before that data is written to [...]
