| gpg.program:: |
| Use this custom program instead of "`gpg`" found on `$PATH` when |
| making or verifying a PGP signature. The program must support the |
| same command-line interface as GPG, namely, to verify a detached |
| signature, "`gpg --verify $signature - <$file`" is run, and the |
| program is expected to signal a good signature by exiting with |
| code 0, and to generate an ASCII-armored detached signature, the |
| standard input of "`gpg -bsau $key`" is fed with the contents to be |
| signed, and the program is expected to send the result to its |
| standard output. |
| |
| gpg.format:: |
| Specifies which key format to use when signing with `--gpg-sign`. |
| Default is "openpgp" and another possible value is "x509". |
| |
| gpg.<format>.program:: |
| Use this to customize the program used for the signing format you |
| chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still |
| be used as a legacy synonym for `gpg.openpgp.program`. The default |
| value for `gpg.x509.program` is "gpgsm". |
