Packing, encrypting and uploading deliverables
Intro
Sometimes when I do client work, I don’t have time to set up Git repositories. When the work is done, I generate the invoice based on the time spent on the project, and I have to ship the deliverables.
Recently I’ve been working on a C# project, and I use a Windows10 laptop where I happen to have a WSL installed.
I could set up a continuous integration (CI) environment to trigger
builds for every commit, and have the binaries available in some artifact
repository, or I could set up a file server for this and use scp or
sftp, but again, that’s not the case.
Transferring the deliverables by e-mail doesn’t always work because sometimes the e-mail provider will block attachments that contain binaries or exceed a certain size.
Because of this I needed a simple solution to just pack the deliverables (with strong enough encryption, data + headers) and just upload them to a file sharing service.
File sharing services
I’ve had a look at existing file sharing services, and specifically I wanted to find something that:
allows direct download (no waiting times, no pop-ups, no ads)
doesn’t require registration
supports upload using
curldoes not require me to use a browser for the upload
is free
There are many such services but these ones were a good fit for this use-case:
100 MB
14 days
500 MB
Upload script
To run this script you’ll need some packages installed:
sudo apt-get install p7zip-full jq makepasswd curlAnd the script itself:
#!/bin/bash
DIR="$1"
PASS=$(makepasswd --chars 40)
ARCHIVE=d1.7z
if [[ -e "$DIR" && -d "$DIR" ]]; then
rm -f $ARCHIVE
find "$DIR" -name "*.dll" -or -name "*.exe" | xargs -I{} rm "{}"
7z a -r -p$PASS -mx=9 -mhe=on -t7z $ARCHIVE "$DIR"
echo "Password:" > pass.txt
echo "$PASS" >> pass.txt
echo "" >> pass.txt
echo "Mirrors:" >> pass.txt
curl -F "file=@$ARCHIVE" https://file.io/?expires=1w | jq -c -r '.link' >> pass.txt
curl --upload-file ./$ARCHIVE https://transfer.sh/$ARCHIVE >> pass.txt
echo "" >> pass.txt
curl --upload-file ./$ARCHIVE https://free.keep.sh >> pass.txt
echo "" >> pass.txt
else
echo "Invalid directory as argument"
fiUsage
Here’s a usage example, creating a directory with a file in it, using the script to create the encrypted archive, and afterwards displaying the urls where it was uploaded together with the password.
user@home:/tmp/sandbox$ mkdir test1 user@home:/tmp/sandbox$ echo "test" > test1/test.txt user@home:/tmp/sandbox$ ./pack_encrypted.sh test1 [...] user@home:/tmp/sandbox$ cat pass.txt Password: tEGiJqdGwiynoCIIDAat6JrTHVCCPb5RFzitrb3o Mirrors: https://file.io/8d1cZVdQ49iY https://transfer.sh/gb7x9w/d1.7z https://free.keep.sh/F44BQzpAUMEbnAzB/d1.7z
