Is it possible to infect a file encrypted using GnuPG?
For example, if I had an encrypted file on an unsecured public ftp server, would someone be able to copy that file and attach a virus/trojan onto the file and then reupload to the server? Then when I next accessed/decrypted, I would then be infected with said virus?
I am currently storing encrypted files on public servers to store data that a few people access. I have just had a sinking feeling that I could be open to attack and possibly have this encrypted data leaked if a trojan was installed.
