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
