This little utility help you make build an Ethereum based key-pair With the private key you can sign messages that people can verify by just using your public key, and the message.
In this folder you find the following files:
+
|-- Dockerfile
|-- docs
| +-- somefile.pdf
|-- keystore
| +-- pw
| +-- UTC--2018-06-02T16-59-15.641342481Z--9c146d53758416334ef4556d9060d641fcd1711c
|-- Makefile
|-- README.md
+-- TT.txt
Never mind the TT.txt file. this is just a temp file where the hash value is kept.
The keystore and docs folders are created when they do not exist.
In keystore you find the active private key and your pw file. Please make sure you protect these files .
In ./docs you can store the files that you want to create a hash for or
that you would like to sign. The file somefile.pdf is just an example.
This also comes with a function to sign a hash (keccak-256sum) of any binary file. The docker will download and build all required tools. For more details on this tools. Check:
These little usefull projects are provided by Mattias Andrée (github: maandree). I would like to thank Mattias for his contribution. All projects (libkeccak and sha3sum) are under ISC license.
All commands are wrapped in a Makefile. You require the following:
- docker 18.03 or better
- GNU Make 3.81 or better
This will build the layer that brings the sha3 (keccak-256sum) functionality to the docker image.
make lib
make key PASSWD="<YourPasswd>"
make signature MESSAGE="HELLOWORLD" PASSWD="<YourPasswd>"
make verify MESSAGE="HELLOWORLD" SIGNATURE="<SignatureOf-HELLOWORLD>"
make signbin FILENAME="<FullPathAndFilename>" PASSWD="<YourPasswd>"
make verifybin FILENAME="<FullPathAndFilename>" SIGNATURE="<SignatureOf-BinaryFile>"
