Pass a path to a *.pem file. A relative path will be resolved to the current working directory (which you can set with the cwd option)

`js
const privateKey = getPrivateKey({
filepath: "private-key.pem",
});
`

Defaults to process.cwd(). Used to resolve the filepath option and used as folder to find *.pem files.

`js
const privateKey = getPrivateKey({
cwd: "/app/current",
});
`

Defaults to process.env. Pass env.PRIVATE_KEY or env.PRIVATE_KEY_PATH to workaround reading environment variables

`js
const privateKey = getPrivateKey({
env: {
PRIVATE_KEY: "-----BEGIN RSA PRIVATE KEY-----\n...",
},
});
