I've written a DLL wrapper for Crypto++ and it works fine - just a few things I'm not clear on,,,
I generate an RSA public/private key pair, then store them in PEM files. I seem to have to call DEREncodePrivateKey on the private key before Base64 encoding and writing to the file, and also having to call BERDecodePrivateKey when reading back the private key. If I use BEREncode on the private key rather than DEREncodePrivateKey when writing the key, I get a BERDecode error on readback. If I try using DEREncodePublicKey on the public key when writing and BERDecodePublicKey when reading I get a BERDecode error. However, if I just write the public key directly I can recover it perfectly. Why is the private key different from the public key in this? DER encoding is a subset of BER, so I can see why that works, but why is it needed rather than just "Save"? Bit confused as to what is actually happening here (even though I have a satisfactory solution - I just want to properly understand it).
