rcrypt

rcrypt provides easy symmetric file encryption for R based on GPG. You must have GPG installed before using rcrypt. Most symmetric GPG encryption options are supported. See the R help documentation for more details. The code can be seen here https://bitbucket.org/bklamer/rcrypt.

Install

GPG must be installed if you wish to use rcrypt. Windows users should install GPG from the program available at https://www.gpg4win.org/. Mac OS users should install GPG from the program available at https://gpgtools.org/. You can check if GPG is installed on your computer by running the following from a command line: gpg --version.

To install rcrypt from CRAN:

install.packages("rcrypt")

To install the development version of rcrypt from Bitbucket:

devtools::install_bitbucket("bklamer/rcrypt")

Examples

# Encryption requires only the input file
encrypt("file.csv")
# You can designate the output location
encrypt("file.csv", output = "path/to/file.csv.gpg")
# Not suggested, but passphrases can also be supplied
encrypt("file.csv", passphrase = "your-passphrase")

Default encryption settings:

# Decryption requires only the input file
decrypt("file.csv.gpg")
# You can designate the output location
decrypt("file.csv.gpg", output = "path/to/file.csv")
# Not suggested, but passphrases can also be supplied
decrypt("file.csv.gpg", passphrase = "your-passphrase")

Warnings

For increased security, GPG normally uses a pop-up box to enter the passphrase. If you wish to bypass this, enter the passphrase through the encrypt or decrypt function as mentioned above. If bypassed, the passphrase may be saved in the script as cleartext, saved in the terminal history in cleartext, and/or available in the list of processes in cleartext.

Improvements Needed
