In HanOostdijk/HOQCenc: Encryption routines

Description

Read and write encrypted files

Usage

read_enc_ascfile(
  filename,
  decode = T,
  key = "1VerySecretPasword",
  trans = "cfcvp"
)

write_enc_ascfile(
  text,
  filename,
  encode = T,
  key = "1VerySecretPasword",
  trans = "cfcvp"
)

read_enc_binfile(
  filename,
  decode = T,
  key = "1VerySecretPasword",
  trans = "cfcvp",
  bufsize = 2000,
  raw2char = F
)

write_enc_binfile(
  text,
  filename,
  encode = T,
  key = "1VerySecretPasword",
  trans = "cfcvp"
)

Arguments

filename	a connection() object or a character string for use in readLines() or writeLines()
decode	Logical scalar indicating if decoding should be done (if TRUE)
key	Character string with key for the xcode() function
trans	Character string with the transformations to be done by the xcode() function#'
text	Character string that has to be written
encode	Logical scalar indicating if encoding should be done (if TRUE)
bufsize	Integer indicating the buffersize to be used for read_enc_binfile
raw2char	Logical scalar indicating if rawToChar conversion should be done in read_enc_binfile

Value

Character string with the data read in case of the read_enc_ascfile function otherwise NULL.

Examples

## Not run: 
han<- write_enc_ascfile("han",'mycoded.txt')
read_enc_ascfile('mycoded.txt',decode = FALSE)
# [1] "L7Gq 63aiI7x92kx"
read_enc_ascfile('mycoded.txt',decode = TRUE)
# [1] "han"

## End(Not run)
