# Cardano Signature Verification

A lightweight typescript library to verify a cip30 datasignature

## Getting Started

```zsh
npm i @cardano-foundation/cardano-signature-verification
```

## Verification

You need a key and a signature from a [cip30 datasignature](https://cips.cardano.org/cips/cip30/#apisigndataaddraddresspayloadbytespromisedatasignature). Use e.g. `window.cardano."wallet_name".enable().then(api => api.signData(...))` or the [signMessage](https://github.com/cardano-foundation/cardano-connect-with-wallet/blob/main/src/hooks/useCardano.ts#L133) function of the [cardano-connect-with-wallet](https://github.com/cardano-foundation/cardano-connect-with-wallet) library to get a valid key and signature.

The plain message and/or the readable address can be provided for testing optionally. [Checkout this examples](index.test.ts).

```ts
verifySignature: (
  signature: string,
  key: string,
  message?: string,
  address?: string
) => boolean;
```

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

GitHub Actions: GitHub context variable exported as environment variable

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
