Apply the encryption key to the file.
Copyright is not encrypted.
Not without knowing your secret keyword to decrypt them.
If data is encrypted with the public key, only the private key can decrypt itAnswer Explanation: Public key encryption uses an asymmetric algorithm, which uses a public key and private key combination for the encryption and decryption process. If data is encrypted with the public key, only the private key can decrypt the data. The public key cannot decrypt a message that was encrypted with the public key. Alternatively, if data is encrypted with the private key, only the public key can decrypt the data.
If data is encrypted with public key, only private key can decrypt it. AGN

The purpose of encryption is to make a message/data unreadable to someone who does not have the key to decrypt it, so it is highly likely that encrypted data will appear to be gibberish.

From the file's Properties dialog box ,click the Advanced button. In the Advanced Attributes dialog box, uncheck Encrypt contents to secure data
Strictly saying it does matter, for instance, if you have a compressed and then encrypted file it would be harder to decrypt it because you might don't know which compression mechanism was used. When you have an encrypted and then compressed file. It's very easy to find out which copression algorithm was used. Thus, you just have to decrypt the file. In the first case you also have guess the compresson algorithm.
