15.2 encryptr package
The encryptr package is our own and allows users to store confidential data in a pseudoanonymised form, which is far less likely to result in re-identification.
Either columns in data frames/tibbles or whole files can be directly encrypted from R using strong RSA encryption.
The basis of RSA encryption is a public/private key pair and is the method used of many modern encryption applications. The public key can be shared and is used to encrypt the information.
The private key is sensitive and should not be shared. The private key requires a password to be set, which should follow modern rules on password complexity. You know what you should do! If the password is lost, it cannot be recovered.
