The goal of redacted is to more easily redact sensitive data in strings. The package provides a set of utility functions for masking sensitive information in text data. This includes functions for redacting credit card numbers, phone numbers, and other sensitive information using regular expressions, as well as a utility function for general masking.
You can install the development version of redacted from GitHub with:
# install.packages("devtools")
devtools::install_github("parmsam/redacted")This is a basic example which shows you how to solve a common problem:
library(redacted)
## basic example code
text <- "My IP address is 192.168.0.1. Please don't share it with anyone."
redacted_text <- redact_ip_addresses(text)
cat(redacted_text)
#> My IP address is [REDACTED]. Please don't share it with anyone.
text <- "Hello, my email address is [email protected]. Please don't share it with anyone."
redacted_text <- redact_email_addresses(text)
cat(redacted_text)
#> Hello, my email address is [REDACTED]. Please don't share it with anyone.It will also redact multiple instances of the sensitive information in the string
text <- "My PIN is 1234. Your PIN is 4321."
redacted_text <- redact_pins(text)
cat(redacted_text)
#> My PIN is [REDACTED]. Your PIN is [REDACTED].Or replace with a custom string using the replace_with option
text <- "My PIN is 1234. Your PIN is 4321."
redact_pins(text, replace_with = "[PIN REDACTED]")
#> [1] "My PIN is [PIN REDACTED]. Your PIN is [PIN REDACTED]."
cat(redacted_text)
#> My PIN is [REDACTED]. Your PIN is [REDACTED].When you pass a single character such as * to replace_with, the matched string will be replaced with asterisks of the same length as the matched string
text <- "My PIN is 1234. Your PIN is 4321."
redacted_text <- redact_pins(text, replace_with = "*")
cat(redacted_text)
#> My PIN is ****. Your PIN is ****.
text <- "My PIN is 1234. Your PIN is 4321."
redacted_text <- redact_pins(text, replace_with = "#")
cat(redacted_text)
#> My PIN is ####. Your PIN is ####.You can also use the redact_pattern() function to redact any custom pattern from text
# Redact email addresses from a string
text <- "Contact me at [email protected]"
redacted_text <- redact_pattern(text, pattern = "\\S+@\\S+")
cat(redacted_text)
#> Contact me at [REDACTED]The redact_all() will attempt to redact using all of the underlying
redact_*() functions or a defined list of functions
text <- c("My phone number is 555-555-1234. My email is [email protected]")
redacted_text <- redact_all(text)
cat(redacted_text)
#> My phone number is [REDACTED]. My email is [REDACTED]
redacted_text <- redact_all(text, redact_funcs = list(redacted::redact_phone_numbers, redacted::redact_ip_addresses))
cat(redacted_text)
#> My phone number is [REDACTED]. My email is [email protected]Note that the redact_*()functions are built using
stringr::str_replace_all() so you can use them on a vector of strings
text <- c("My PIN is 1234.", "Your PIN is 4321.", "Their PIN is 1111.")
redacted_text <- redact_pins(text)
cat(redacted_text)
#> My PIN is [REDACTED]. Your PIN is [REDACTED]. Their PIN is [REDACTED].Contributions are welcome! Please open an issue to report a bug or suggest a new feature, or submit a pull request to contribute code changes.
