# agetar
|
||||
actual description and development pending... I am lazy
|
||||
`agetar` is a simple wrapper around `tar` and `age` to easily pack files into an encrypted tar archive or extract files from an encrypted tar archive.
|
||||
|
||||
## dependencies
|
||||
- a posix-compliant shell
|
||||
- either `bsdtar` or `tar` (`bsdtar` takes priority)
|
||||
- [age](https://github.com/FiloSottile/age)
|
||||
|
||||
# usage
|
||||
```
|
||||
usage:
|
||||
agetar -e (-r RECIPIENT | -R PATH)... [-a] [-o OUTPUT] [--] FILES...
|
||||
agetar -e -p [-a] [-o OUTPUT] [--] FILES...
|
||||
agetar -d [-i PATH]... [-o OUTPUT] [--] FILES...
|
||||
|
||||
options:
|
||||
-e encrypt the input files to an output tar
|
||||
-d decrypt the input tar to output files
|
||||
-o OUTPUT encrypting: write output tar to OUTPUT. stdout if omitted
|
||||
decrypting: directory to extract to. PWD if omitted
|
||||
-a encrypt to a PEM encoded format
|
||||
-p encrypt with a passphrase
|
||||
-r RECIPIENT encrypt to the specified RECIPIENT. can be repeated
|
||||
-R PATH encrypt to the recipients listed at PATH. can be repeated
|
||||
-i PATH decrypt using the identity file at PATH. can be repeated
|
||||
|
||||
at least one FILE is required for both encrypting and decrypting
|
||||
if multiple are present, each will be processed with the same identities
|
||||
|
||||
you probably want an OUTPUT when encrypting, even if it's not required
|
||||
(age will yet at you for that anyway unless you also use -a)
|
||||
|
||||
most of these options are passed directly to age(1). see its man page for
|
||||
more details.
