## Quickstart

### Installing the library

```bash
npm install ocsp-hashes --save
```


### Using the library

```javascript
import * as ocspHashes from 'ocsp-hashes';

/**
 * Given a pem certificate file and issuer cert file.
 * @param {string} certPath The path to a certificate file.
 * @param {string} issuerCertPath The path to a issuer certificate file.
 * @param {string} hashingAlgorithm - default sha256.
 * @param {boolean} disableFilePathValidations - default false - only for development or if you know what you are doing.
 */
const ocspHashes = await ocspHashes.getOCSPHashes(certPath, issuerCertPath, hashingAlgorithm, disableFilePathValidations);
console.log('The ocsp object:');
console.log(ocspHashes);

const ocspHashes = await ocspHashes.getOCSPHashes(certPath, issuerCertPath, hashingAlgorithm);
console.log('The ocsp object:');
console.log(ocspHashes);

const ocspHashes = await ocspHashes.getOCSPHashes(certPath, issuerCertPath);
console.log('The ocsp object:');
console.log(ocspHashes);
