Include file(s)

[Jonathan Wood]

So, I'm seeing if I can compile the examples given at https://cryptopp.com/wiki/Advanced_Encryption_Standard. Unfortunately, those examples don't show any include statements. I included cryptlib.h but still have many symbols undefined.

Is there a master include file I can include so that I can compile that code?

Refresh your browser. The example was just updated.

Typically you include cryptlib.h for the various interfaces. Then you
include specific headers, like rijndael.h for AES, modes.h for a mode
like CBC, hex.h for hex encoding, filters.h for
StreamTransformationFilter.

Yes, I see it was updated now. I seem to be having a hard time though. Are there any examples that show 1) encrypting non-string data (BYTE*), and 2) encrypting using a password?

Thanks,

For (1), a StringSource handles both char* and byte*. See
https://www.cryptopp.com/wiki/StringSource.

For (2), you generally want a KDF or password-based KDF. See
https://www.cryptopp.com/wiki/KeyDerivationFunction.

I think the state of the art for {PB}KDF is Krawczyk's HKDF. The HKDF
page shows you how to derive independent keys using HKDF. See
https://www.cryptopp.com/wiki/HKDF.

Going beyond simple key derivation and encryption, you can achieve
very good security with an Integrated Encryption Scheme (IES). IES is
IND-CCA2, which is a strong notion of security. See
https://www.cryptopp.com/wiki/Integrated_Encryption_Scheme.
