SHA-256 hash

Calculate the SHA-256 hash of each element of a character vector.

Usage

hash_sha256(x)

hash_raw_sha256(x)

hash_obj_sha256(x, serialize_version = 2)

hash_file_sha256(paths)

Arguments

x

Character vector. If not a character vector, then as.character() is used to try to coerce it into one. NA entries will have an NA hash.

serialize_version

Workspace format version to use, see base::serialize().

paths

Character vector of file names.

Value

hash_sha256() returns a character vector of hexadecimal SHA-256 hashes.

hash_raw_sha256() returns a character scalar.

hash_obj_sha256() returns a character scalar.

hash_file_sha256() returns a character vector of SHA-256 hashes.

Details

hash_raw_sha256() calculates the SHA-256 hash of the bytes of a raw vector.

hash_obj_sha256() calculates the SHA-256 hash of an R object. The object is serialized into a binary vector first.

hash_file_sha256() calculates the SHA-256 hash of one or more files.
