The functions bin2hex
and hex2bin
convert between binary (raw)
vectors and corresponding string in hexadecimal notation. The random
function generates n
crypto secure random bytes.
Arguments
- bin
raw vector with binary data to convert to hex string
- hex
a string with hexadecimal characters to parse into a binary (raw) vector.
- ignore
a string with characters to ignore from
hex
. See example.- n
number of random bytes or numbers to generate
Examples
# Convert raw to hex string and back
test <- charToRaw("test 123")
x <- bin2hex(test)
y <- hex2bin(x)
stopifnot(identical(test, y))
stopifnot(identical(x, paste(test, collapse = "")))
# Parse text with characters
x2 <- paste(test, collapse = ":")
y2 <- hex2bin(x2, ignore = ":")
stopifnot(identical(test, y2))
