unlock_gpg_key_passphrase: Functions that attempts to unlock a gpg key for decryption

In knitrdata: Data Language Engine for 'knitr' / 'rmarkdown'

Description

This function will attempt to unlock a specific GPG key by first encrypting a small amount of information using the (public) key and then immediately decrypting it using the (private) key, thereby causing the keyring to temporarily store the key passphrase. This can be helpful if one is trying to knit a document with encrypted data chunks, but the key for those data chunks is locked with a passphrase. See the package vignette section Workarounds for GPG data chunk error: Password callback did not return a string value for more details.

Usage

unlock_gpg_key_passphrase(
  id = ifelse(is.null(name), ifelse(is.null(email), NULL,
    gpg::gpg_list_keys()$id[gpg::gpg_list_keys()$email == email]),
    gpg::gpg_list_keys()$id[gpg::gpg_list_keys()$name == name]),
  name = NULL,
  email = NULL
)

Arguments

id	Identifier of the GPG key
name	Name associated with the desired GPG key
email	Email associated with the desired GPG key

Value

Will return the identifier of the GPG key that was unlocked.
