des encryption example

Recently in the collation of data encryption and decryption, integration of C/s,. NET, Java three platform data encryption and decryption materials, so that three platform invoke related functions to decrypt the results are consistent and compatible. PS: The final collation of information may be issued in the form of electronic PDF, if it is beneficial to you, please pay attention to. C + + is directly usi

Engine object, to do some allocation of space and initialization of the work, instead of new to complete the allocation of space.MyKey = Keybuilder.buildkey (Keybuilder.type_des, Keybuilder.length_des, false);Then this code is used to create uninitialized key objects, before we talk about objects you must give them space before you use them! The Buildkey out here is just an object that has a blank space assigned to it, and you need to use the Setkey function to initialize the key later.((Deskey
