RSA has some weaknesses against chosen plain text attacks.
RSA is just an algorithm, so if you talk of chosen plaintext
or chosen ciphertext attacks, it needs to be in the context
of an encryption method. OAEP is a response primarily to
a chosen ciphertext vulnerabili

1) It doesn't
2) Do you mean with a 1024-bit modulus the encryption block size
is 936? Because of padding.

The SSL_set_fd and SSL_get_fd take an int as parameter for the socket.
While this was fine on windows 32 bit and on all *nix variants (even 64

I hope this can be fixed. Because a SOCKET on windows 64 bit is a
