In sodium: A Modern and Easy-to-Use Crypto Library

Description

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.

Usage

bin2hex(bin)

hex2bin(hex, ignore = ":")

random(n = 1)

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))
