transfer.sh Go Report Card Docker pulls Build Status

Easy and fast file sharing from the command-line. This code contains the server with everything you need to create your own instance.

Transfer.sh currently supports the s3 (Amazon S3), gdrive (Google Drive), storj (Storj) providers, and local file system (local).

Disclaimer

@stefanbenten happens to be a maintainer of this repository and the person who host a well known public installation of the software in the repo.

The two are anyway unrelated, and the repo is not the place to direct requests and issues for any of the pubblic installation.

No third-party public installation of the software in the repo will be advertised or mentioned in the repo itself, for security reasons.

The official position of me, @aspacca, as maintainer of the repo, is that if you want to use the software you should host your own installation.

Usage

Upload:

$ curl -v --upload-file ./hello.txt https://transfer.sh/hello.txt

Encrypt & Upload:

$ gpg --armor --symmetric --output - /tmp/hello.txt | curl --upload-file - https://transfer.sh/test.txt

Download & Decrypt:

$ curl https://transfer.sh/1lDau/test.txt | gpg --decrypt --output /tmp/hello.txt

Upload to Virustotal:

$ curl -X PUT --upload-file nhgbhhj https://transfer.sh/test.txt/virustotal

Deleting

$ curl -X DELETE <X-Url-Delete Response Header URL>

Request Headers

Max-Downloads

$ curl --upload-file ./hello.txt https://transfer.sh/hello.txt -H "Max-Downloads: 1" # Limit the number of downloads

Max-Days

$ curl --upload-file ./hello.txt https://transfer.sh/hello.txt -H "Max-Days: 1" # Set the number of days before deletion

X-Encrypt-Password

Beware, use this feature only on your self-hosted server: trusting a third-party service for server side encryption is at your own risk

$ curl --upload-file ./hello.txt https://your-transfersh-instance.tld/hello.txt -H "X-Encrypt-Password: test" # Encrypt the content sever side with AES265 using "test" as password

X-Decrypt-Password

Beware, use this feature only on your self-hosted server: trusting a third-party service for server side encryption is at your own risk

If you want to use TLS using lets encrypt certificates, set lets-encrypt-hosts to your domain, set tls-listener to :443 and enable force-https.

If you want to use TLS using your own certificates, set tls-listener to :443, force-https, tls-cert-file and tls-private-key.

Development

Switched to GO111MODULE

go run main.go --provider=local --listener :8080 --temp-path=/tmp/ --basedir=/tmp/

Build

$ git clone git@github.com:dutchcoders/transfer.sh.git
$ cd transfer.sh
$ go build -o transfersh main.go

Docker

For easy deployment, we've created an official Docker container. There are two variants, differing only by which user runs the process.

The default one will run as root:

docker run --publish 8080:8080 dutchcoders/transfer.sh:latest --provider local --basedir /tmp/

The one tagged with the suffix -noroot will use 5000 as both UID and GID:

docker run --publish 8080:8080 dutchcoders/transfer.sh:latest-noroot --provider local --basedir /tmp/

Building the Container

You can also build the container yourself. This allows you to choose which UID/GID will be used, e.g. when using NFS mounts:

# Build arguments:
# * RUNAS: If empty, the container will run as root.
#          Set this to anything to enable UID/GID selection.
# * PUID:  UID of the process. Needs RUNAS != "". Defaults to 5000.
# * PGID:  GID of the process. Needs RUNAS != "". Defaults to 5000.

docker build -t transfer.sh-noroot --build-arg RUNAS=doesntmatter --build-arg PUID=1337 --build-arg PGID=1338 .

S3 Usage

For the usage with a AWS S3 Bucket, you just need to specify the following options:

If you specify the s3-region, you don't need to set the endpoint URL since the correct endpoint will used automatically.

Custom S3 providers

To use a custom non-AWS S3 provider, you need to specify the endpoint as defined from your cloud provider.

Storj Network Provider

To use the Storj Network as a storage provider you need to specify the following flags:

Creating Bucket and Scope

You need to create an access grant (or copy it from the uplink configuration) and a bucket in preparation.

To get started, log in to your account and go to the Access Grant Menu and start the Wizard on the upper right.

Enter your access grant name of choice, hit Next and restrict it as necessary/preferred. Afterwards continue either in CLI or within the Browser. Next, you'll be asked for a Passphrase used as Encryption Key. Make sure to save it in a safe place. Without it, you will lose the ability to decrypt your files!

Afterwards, you can copy the access grant and then start the startup of the transfer.sh endpoint. It is recommended to provide both the access grant and the bucket name as ENV Variables for enhanced security.

Example:

export STORJ_BUCKET=<BUCKET NAME>
export STORJ_ACCESS=<ACCESS GRANT>
transfer.sh --provider storj

Google Drive Usage

For the usage with Google drive, you need to specify the following options:

Creating Gdrive Client Json

You need to create an OAuth Client id from console.cloud.google.com, download the file, and place it into a safe directory.

Usage example

go run main.go --provider gdrive --basedir /tmp/ --gdrive-client-json-filepath /[credential_dir] --gdrive-local-config-path [directory_to_save_config]

Shell functions

Bash, ash and zsh (multiple files uploaded as zip archive)

Add this to .bashrc or .zshrc or its equivalent
transfer() (if [ $# -eq 0 ]; then printf "No arguments specified.\nUsage:\n transfer <file|directory>\n ... | transfer <file_name>\n">&2; return 1; fi; file_name=$(basename "$1"); if [ -t 0 ]; then file="$1"; if [ ! -e "$file" ]; then echo "$file: No such file or directory">&2; return 1; fi; if [ -d "$file" ]; then cd "$file" || return 1; file_name="$file_name.zip"; set -- zip -r -q - .; else set -- cat "$file"; fi; else set -- cat; fi; url=$("$@" | curl --silent --show-error --progress-bar --upload-file "-" "https://transfer.sh/$file_name"); echo "$url"; )

Now you can use transfer function

$ transfer hello.txt

Bash and zsh (with delete url, delete token output and prompt before uploading)

Add this to .bashrc or .zshrc or its equivalent
