I like crypto. Need I say more?

comment How are symmetric cryptographic keys stored?
I'm going to migrate to Security.SE as that is the better place for this question. They deal with more practical issues, we deal with mostly theoretical questions related to cryptography.

@axel, please don't cross-post to multiple sites. It is against SE rules.

What @yyyyyyy said. Now, I'm going to ask the cryptography related question, why would you want to do this?

To answer the questions: A) no, B) likely also no as I don't believe you have anything that is really secure. Cryptographers are skeptical of new ciphers/protocols. Even if they come from seasoned professionals.

@RickyDemer, If so, I hope the OP isn't just planning on using a stream cipher. That was my initial guess too.

@ampersand is there something missing in the PDF that is downloaded on the left hand side? It appears to be the whole thing to me.

Are you saying you came up with a way to do end-to-end encryption between two individuals that share no keys in advance?
