    PGP/GPG Email encryption, with RSA-4096, ECC(Elliptic-Curve), RSA-16384 ?

    Posted: 17 Apr 2019 08:57 AM PDT

    Hiya,

    Which one of these encryptions is most secure for PGP/GPG email encryption:

    RSA-4096,

    ECC(Elliptic-Curve),

    RSA-16384

    ?

    Which one are N~SA and F~BI Proof?

    How to encrypt email with RSA-16384 Public/Private key for PGP/GPG ? how secure is the RSA-4096, ECC(Elliptic-Curve) and RSA-16384 comparing to each other in sequence? Is there any more secure way to create PGP/GPG further secure than above algorithms?

    Tnx

    I'm trying to create a CSPRNG, how bad is my idea?

    Okay, so my idea is:

    Take random input from /dev/random on POSIX-like OSes, on Windows use CryptGenRandom.

    then run AES-256 over it. (in software, I don't trust the AES instructions, nor do I trust the data straight out of the OSes random interface, hence doing all of this)

    mix it (probably with XoRoShiRo).

    re-AES-256 it.

    re-mix it.

    I don't know a whole lot about cryptography, but I can't really see any issues with this idea; hence asking this question.

    Currently I'm only planning on using it for testing my libraries, but I'm writing a video codec and at some point may need to support encrypting frames or sub-frame blocks or something.
