raw2hex convers a raw vector into hexadecimal representation
optional separator string
sep is omitted or
NULL then the resulting character
vector will have as many elements as the raw vector. Otherwise the
elements are concatenated using the specified separator into one
character string. This is much more efficient than using
paste(raw2hex(x), collapse=sep), but has the same effect.
Character vector with the hexadecimal representation of the raw vector.
1 2 3 4 5 6 7 8 9
raw2hex(PKI.digest(raw(), "SHA1"), "") raw2hex(PKI.digest(raw(), "MD5"), ":") ## this is jsut a performance comparison and a test that ## raw2hex can handle long strings x <- as.raw(runif(1e5) * 255.9) system.time(h1 <- raw2hex(x, " ")) system.time(h2 <- paste(raw2hex(x), collapse=" ")) stopifnot(identical(h1, h2))
