Hi,
1. Is the AES-Encryption of a file by gnupg vulnerable to known-
plaintext attacks ?
No.
2. Does this depend on the lenght of the plaintext ?
No.
2.1 Is a strong Passphrase even safe, if the size of the known
plaintext is just 1 Byte or even 10 GB ?
Yes.
3. Is it possible for sombody, who does not know the strong
Passphrase, to guess reliably, if the encrypted data contains a
known file ?
Cannot be answered in the context of this question. It depends on the
cipher mode.
4. Why or Why not (1.,2.,3 )?
