Encrypted end to end file transfer
We wanted to make end to end encryption as simple as possible using standard tools. wsend-gpg is a very simple 5 line script to get this done.

wsend-gpg requires wsend and gpg.
wsend-gpg uses wsend.net for backend file handling.
wget https://raw.githubusercontent.com/abemassry/wsend-gpg/master/install.sh -O - | bash
alias wsend="~/.wsend/wsend"; alias wsend-gpg="~/.wsend/wsend-gpg"; alias wget-gpg="~/.wsend/wget-gpg"
Note: This install command appends the alias to your .bashrc or equivalent
#!/bin/bash
#
gpg -c -z 9 --require-secmem --cipher-algo AES256 --s2k-cipher-algo AES256 --s2k-digest-algo SHA512 --s2k-mode 3 --s2k-count 65000000 --compress-algo BZIP2 "$1"

- Encrypt file
- Send file right from the command line without having to specify a directory
- Gives you a url
- Integrates well with unix pipes
- Send a file without registering
- User accounts available with large amounts of storage space

The API is REST like in the sense that there is a representational transfer of state. It isn't REST like in the sense that the only transport method that is used is HTTP POST.
To get a user id:
curl -F "start=1" https://wsend.net/createunreg
This should be saved to a file or a database
To send a file:
curl -F "uid=$id" -F "filehandle=@$fileToSend" https://wsend.net/upload_cli
Where $id is the id from the previous request and $fileToSend is the file you would like to send.
To see if the user has storage space available to send this file:
curl -F "uid=$id" -F "size=$fileToSendSize" https://wsend.net/userspaceavailable
Where $fileToSendSize is the filesize in bytes.
To register a user:
curl -F "uid=$id" -F "email=$email" -F "password=$password" https://wsend.net/register_cli
You want to protect the password from showing up anywhere as security measure. For the wsend command line script the password is not echoed and passed directly as a variable.
To log in a user:
curl -F "email=$email" -F "password=$password" https://wsend.net/login_cli
- Q: How does this differ from wsend
A: wsend-gpg uses wsend for file transfer to get a url for a file. wsend.net is used as a backend file store
- Q: How is this different from
scp?
A: scp is useful for transferring from one system to the other using the ssh protocol. wsend-gpg differs in that both systems don't have to be up and running, the transfer is done using the https protocol, and there are always two steps.
- Q: Why did you program this in Bash wasn't that painful? Bash isn't meant to do these things, you could have used python with pip, nodejs with npm, or ruby with rubygems.
A: While it was painful we wanted this script to be ubiquitous as possible and bash was installed on all of our *nix machines. We do have plans to write this in the languages you mention and will work towards this in the future. If you would like to write a client in one of these languages it would be something we would both appreciate and support. *Update node-wsend now available.
- Q: When are the Enthusiast and Hero accounts going to become available?
A: As soon as we generate enough income with the Supporter accounts we can purchase more servers and more space. We do not want to degrade the quality of paid accounts because paying customers deserve the best treatment. We do not want to offer services that we can't fully 100% support until we are ready to.
- Q: What is the max filesize?
A: For the Unregistered Account it is 200MB, for the Free account it is 2GB, for the Paid accounts it is 10GB. Since wsend-gpg encrypts the file using gpg it might take a long time to encrypt for a large filesize, also the disk is used to store the encrypted file temporarily so make sure you don't run out of space.
- Q: I have an unregistered account, why is my file not loading?
A: We remove files from unregistered accounts when they become 30 days old or space is needed on the server whichever comes first.
- Q: I have a free account, why are my files missing?
A: We remove files from free accounts when they become 30 days old or space is needed on the server whichever comes first.
- Q: But why, that doesn't seem right, no other service does this?
A: The wsend program and service is primarily provided for sending files. We have to maintain the best service possible for paying users, once the paying user-base grows we can support more benefits for the unregistered and free accounts. This service is not meant to compete with other services that store files for free, it can be used as a quick and easy way to send files.
- Q: Can I use the wsend script to interface with another web service?
A: By all means, its GPL licensed and you can adapt it to whatever service you would like or create your own.
- Q: I have a problem but it is not listed here, who should I ask?
A: While we will try to respond to all requests, you can contact us at https://wsend.net/about If you are a paying user we will definitely respond and will not rest till your problem is resolved. Just fill out the contact form with your email that is registered to your paid account. Paid accounts are so important to us because it not only keeps the lights on and the hard drives spinning, it validates what we are doing and it says you support us, you support the community, and you support an open internet where everyone can exchange ideas. You are also joining us in contributing to something larger than ourselves.

In this directory the executable bash script wsend is stored, along with the README.md documentation, the GPL COPYING licence, a file called version which stores the version and which wsend checks against the github repo to determine whether it should install updates, and a file called .id, which is an identifier for the command line user.

The executable bash script, this can send files and also install the ~.wsend/ directory. The only user file it changes is the .bashrc file by appending the alias to the end. If you have bash installed but use another popular shell it will install it to that .*rc file
