uploadenc

Writes client-uploaded files directly to Amazon S3, encrypting them to a given public key in the process. Works great for securely sending yourself personal pictures from your phone, for example.

Overview:

• Uses node's https module to listen on given port (default 443)
• By default serves index.html with a simple html form containing an upload input that accepts multiple files
• When client clicks upload, data is encrypted on the fly and sent to a configured S3 bucket (using AWS credentials)

Needs a 1024+ bit RSA public key and working SSL certs to function. To create RSA keys:

openssl genrsa -out private.pem 4096

openssl rsa -in private.pem -pubout > key.pub

private.pem is to be kept in a secure place, preferrably completely offline. Do not keep private.pem anywhere on the server. key.pub does need to be on the server, alongside this code.

Needs at least Node v6.11 to work properly. Works fine on a Raspberry Pi, even with multi-GB file uploads.
