\title{SHA-1 hash}
\usage{
hash_sha1(x)
hash_raw_sha1(x)
hash_obj_sha1(x, serialize_version = 2)
hash_file_sha1(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_sha1()} returns a character vector of hexadecimal
SHA-1 hashes.
\code{hash_raw_sha1()} returns a character scalar.
\code{hash_obj_sha1()} returns a character scalar.
\code{hash_file_sha1()} returns a character vector of SHA-1
hashes.
}
\description{
Calculate the SHA-1 hash of each element of a character vector.
}
\details{
\code{hash_raw_sha1()} calculates the SHA-1 hash of the bytes
of a raw vector.
\code{hash_obj_sha1()} calculates the SHA-1 hash of an R
object. The object is serialized into a binary vector first.
\code{hash_file_sha1()} calculates the SHA-1 hash of one or
more files.
}
\examples{
hash_sha1(c("foo", NA, "bar", ""))
