Sigserver

Server to allow uploading and serving of signatures.

Prequisites

1. Node

Running Server

npm start

Environment Variables

There are a few environment variables you can set to modify the server's behavior:

1. SIGNATURE_PATH - where to store the signature files. if not set, will default to ./public/signatures
2. PORT - configure the listening port. if not set, defaults to 8080

If you want to enable TLS, set the following two variables. Failure to set both will result in TLS being disabled. For more information you can read this.

1. CERT_PATH - path of the cert, eg) server.crt
2. KEY_PATH - path of the key, eg) server.key

Simple Manual System Test

# start server
npm start

# generate binary file, binary.dat
i=0; while [ $i -lt 256 ]; do echo -en '\x'$(printf "%0x" $i)''  >> binary.dat; i=$((i+1));  done\n

# curl server, uploading binary.dat
curl --header "Data-Filename: file.dat" --header "Content-Type:application/octet-stream" --location --request POST "http://127.0.0.1:8080/upload" --data-binary "@./binary.dat"

# verify upload was successful
cat ./public/signatures/file.dat

# verify through browser or curl endpoint
curl http://localhost:8080/signatures
