Today I'm posting a sample I did some time ago which shows how to generate key pairs, encrypt and decrypt data with C++ and CryptoAPI. The comments in the code should be self-explanatory.<SAMPLE>複製 // INCLUDES #include "stdio.h" #include "conio.h" #include "window...
Encrypt and decrypt application data by usingCryptProtectDataandCryptUnprotectData. NoteAlthoughCryptProtectDataandCryptUnprotectDatause entropy, the encryption is only as strong as the data supplied for encryption. It is important to supply a strong password. A user who supplies a weak password can weaken ...

As for key management - i guess i can have the server create a new key every preconfigured period of time, encrypt it with the old key and post it to the data store for the client to decrypt and start using, but it's kind of overkill for my needs. ...
