\title{MD5 hash}
\usage{
hash_md5(x)
hash_raw_md5(x)
hash_obj_md5(x, serialize_version = 2)
hash_file_md5(paths)
}
\arguments{
\item{x}{Character vector. If not a character vector, then
\code{\link[=as.character]{as.character()}} is used to try to coerce it into one. \code{NA} entries
will have an \code{NA} hash.}
\item{serialize_version}{Workspace format version to use, see
\code{\link[base:serialize]{base::serialize()}}.}
\item{paths}{Character vector of file names.}
}
\value{
\code{hash_md5()} returns a character vector of hexadecimal MD5
hashes.
\code{hash_raw_md5()} returns a character scalar.
\code{hash_obj_md5()} returns a character scalar.
}
\description{
Calculate the MD5 hash of each element of a character vector.
}
\details{
\code{hash_raw_md5()} calculates the MD5 hash of the bytes
of a raw vector.
\code{hash_obj_md5()} calculates the MD5 hash of an R
object. The object is serialized into a binary vector first.
\code{hash_file_md5()} calculates the MD5 hash of one or more
files.
}
\examples{
hash_md5(c("foo", NA, "bar", ""))
}
\seealso{
\code{\link[tools:md5sum]{tools::md5sum()}} for a base R MD5 function that works on
files.
