1gpg.program:: 2 Use this custom program instead of "`gpg`" found on `$PATH` when 3 making or verifying a PGP signature. The program must support the 4 same command-line interface as GPG, namely, to verify a detached 5 signature, "`gpg --verify $signature - <$file`" is run, and the 6 program is expected to signal a good signature by exiting with 7 code 0, and to generate an ASCII-armored detached signature, the 8 standard input of "`gpg -bsau $key`" is fed with the contents to be 9 signed, and the program is expected to send the result to its 10 standard output. 11 12gpg.format:: 13 Specifies which key format to use when signing with `--gpg-sign`. 14 Default is "openpgp" and another possible value is "x509". 15 16gpg.<format>.program:: 17 Use this to customize the program used for the signing format you 18 chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still 19 be used as a legacy synonym for `gpg.openpgp.program`. The default 20 value for `gpg.x509.program` is "gpgsm".
