15.9 Encrypting a file
Encrypting the object within R has little point if a file with the disclosive information is still present on the system. Files can be encrypted and decrypted using the same set of keys.
To demonstrate, the included dataset is written as a .csv file.
Check that the file can be decrypted prior to removing the original file from your system.
Warning: it is strongly suggested that the original unencrypted data file backed up in a secure system in case de-encryption is not possible, e.g., the private key file or password is lost.
