In mattmoo/daohtools: Tools for working with registry data and transforming to days alive and out of hospital (DAOH)

Encrypts a column (or columns) from a file, with a given password, generates lookup tables, and zips the tables into an encrypted zip file with the password. Files are (optionally) saved to a timestamped directory, and a timestamped zip file is then (optionally) generated. The data with encrypted ID columns will be saved to the specified path, with the same file name as the original, but

Description

It's your responsibility to securely erase the identifiable data. Use something that specifically overwrites it, your operating system will not do that by default.

Usage

encrypt.col(
  input.file.path,
  col.names,
  password = NULL,
  save.encrypted.table = T,
  save.lookup.table = T,
  save.password = T,
  save.zip = T,
  table.save.dir = NULL,
  lookup.save.dir = NULL,
  encrypted.column.suffix = ".IDencrypted",
  encrypted.file.suffix = "_IDencrypted",
  output.to.console = T
)

Arguments

input.file.path	Character file path readable by data.table::fread
col.names	Character vector of columns to encrypt.
password	The password with which to encrypt. If NULL, the user will be prompted. Probably not best practice to store this unencrypted in scripts. Could maybe move to certificates one day. (Default: NULL)
save.encrypted.table	Save encrypted data as CSV to table.save.path (Default: T)
save.lookup.table	Save lookup tables for each encrypted column (Default: T)
save.password	Save the password in a plain text file (Default: T)
save.zip	Save all generated files in an encrypted ZIP file with same password, this probably requires Rtools, and for the zip function to be in Windows PATH (Default: T)
table.save.dir	Character directory to save table with encrypted data to (Default: same as input)
lookup.save.dir	Character directory to save lookup tables to (Default: same as input)
encrypted.column.suffix	Character to append to original column names to indicate that they are encrypted. (Default: '.IDencrypted')
encrypted.file.suffix	Character to append to original file names to indicate that they are encrypted. (Default: '_IDencrypted')
output.to.console	Say what's going on in the console (Default: T)
