In gpg: GNU Privacy Guard for R

PGP Signatures

Description

Utilities to create and verify PGP signatures.

Usage

gpg_verify(signature, data = NULL, error = TRUE)

gpg_sign(data, signer = NULL, mode = c("detach", "normal", "clear"))

Arguments

signature	path or raw vector for the gpg signature (contains the PGP SIGNATURE block)
data	path or raw vector with data to sign or verify. In gpg_verify this should be NULL if signature is not detached (i.e. clear or normal signature)
error	raise an error if verification fails because you do not have the signer public key in your keyring.
signer	(optional) vector with key ID's to use for signing. If NULL, GPG tries the user default private key.
mode	use normal to create a full OpenPGP message containing both data and signature or clear append the signature to the clear-text data (for email messages). Default detach only returns the signature itself.
