transfer.sh

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

The service at transfersh.com is of unknown origin and reported as cloud malware.

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

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 [email protected]: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:

provider --provider s3
aws-access-key (either via flag or environment variable AWS_ACCESS_KEY)
aws-secret-key (either via flag or environment variable AWS_SECRET_KEY)
bucket (either via flag or environment variable BUCKET)
s3-region (either via flag or environment variable S3_REGION)

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:

provider --provider storj
storj-access (either via flag or environment variable STORJ_ACCESS)
storj-bucket (either via flag or environment variable STORJ_BUCKET)

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:

provider
gdrive-client-json-filepath
gdrive-local-config-path
basedir

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
