CBOR Object Signing and Encryption

This repository is home to an incomplete implementation of RFC 8152 written in Typescript.

Initialising submodules

This project uses a Git submodule from the repository at github.com/cose-wg/Examples.git. That repository contains test cases. So you will need to pull them down for tests to run. To activate the submodule, run the following:

git submodule init
git submodule update

Signing

The following algorithms are supported for COSE_Sign1

| Signing Algorithm | Description | | ---------------------------------------------------------------- | --------------------------------------------------------------------------------------------- | | ES256 | Elliptic Curve Digital Signature Algorithm using the P-256/brainpoolP256r1 curve with SHA-256 | | ES384 | Elliptic Curve Digital Signature Algorithm using the P-384/brainpoolP384r1 curve with SHA-384 | | ES512 | Elliptic Curve Digital Signature Algorithm using the P-512/brainpoolP512r1 curve with SHA-512 | | EdDSA | Elliptic Curve Digital Signature Algorithm using the Ed25519/Ed448 curve with SHA-512 | | PS256 | RSA Probabilistic Signature Scheme (RSASSA-PSS) with SHA-256 | | PS384 | RSA Probabilistic Signature Scheme (RSASSA-PSS) with SHA-384 | | PS512 | RSA Probabilistic Signature Scheme (RSASSA-PSS) with SHA-512 |
