For round-trip testing of ``cose_sign.js` and `cose_verify.js` take some`
JSON, e.g. { "Foo" : "Bar }`, CBOR package, COSE sign, compress and base45
convert it for use in a QR:
1. COSE sign
1. compact the JSOn into CBOR
1. sign and package as a COSE message
1. ZLIB compress
1. Base45 encode
1. COSE verify
1. Base45 decode
1. ZLIB decompress
1. check the signature on the COSE message
1. unpack the CBOR into JSON
1. Generate the CSCA and DSC with `./gen-csca-dsc.sh` `
1. Ensure the dependencies are installed: npm install`
1. Run the command: echo "{'A': 1234}" | npm run sign | npm run verify`
1. You should see the output: {"A": 1234}`
Or the larger example:
`
echo '{ "Foo":1, "Bar":{ "Field1": "a value", "integer":1212112121 }}' | npm --silent run sign > barcode
cat barcode | | npm run verify
Which should output:
`
{
"Foo": 1,
"Bar": {
"Field1": "a value",
"integer": 1212112121
}
}
