B64F

Base64 Encode/Decode multiple files.

How to use

create .b64f file under working directory with list of files that should be encoded to base64 file. Each entry support glob pattern, for example:
```
pkg/util/testdata/*
**/*.yml
```
run the following command to encode the listed files. This will create a new sibling file for each listed file with additional .b64 extension, e.g. pkg/util/testdata/a.key will produce pkg/util/testdata/a.key.b64. Note that it will overwride the .b64 file if it already existed.
```
go run -mod=mod github.com/telkomindonesia/b64f encode
```
to decode back the .b64 files, run the following command on the same directory. Note that it will overwride the decoded file if it already existed.
```
go run -mod=mod github.com/telkomindonesia/b64f decode
```

Instead of using go run you can download pre-compiled binary from Github releases page.

Another alternative is to use docker, e.g.

docker run --rm \
    -v "$PWD:$PWD" -w "$PWD" \
    ghcr.io/telkomindonesia/b64f:latest \
    [decode|encode]

You can use makefie to make the command simpler, for example:

b64f: mode ?= "decode"
b64f:
    go run -mod=mod github.com/telkomindonesia/b64f $(mode)

which can then be used using make b64f or make b64f mode=encode

see testdata folder for example.
