Pem2Jwk
A tool to convert a PEM file to a JSON Web Key (JWK). AThe package provides methods to convert both public and private PEM files, as well as a method to convert a private PEM to a public JWK.
Requirements
- OpenSSL 1.1.0 or later
Table of Contents
fromPublic
This method takes a public PEM file and converts it to a JSON Web Key (JWK).
Syntax
Pem2Jwk.fromPublic<T>(publicPem: PEM, extraKeys?: T): PublicJWK<T>Parameters
-
publicPem: The public PEM file. Can be a string or a Buffer. -
extraKeys(optional): An object that provides additional information to be included in the JWK.
Return Value
The public JWK.
Example
const publicPem = `-----BEGIN PUBLIC KEY-----
...
-----END PUBLIC KEY-----`;
const publicJwk = Pem2Jwk.fromPublic(publicPem);
console.log(publicJwk);fromPrivate
This method takes a private PEM file and converts it to a JSON Web Key (JWK).
Syntax
Pem2Jwk.fromPrivate<T>(privatePem: PEM, extraKeys?: T): PrivateJWK<T>Parameters
-
privatePem: The private PEM file. Can be a string or a Buffer. -
extraKeys(optional): An object that provides additional information to be included in the JWK.
Return Value
The private JWK.
Example
const privatePem = `-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----`;
const privateJwk = Pem2Jwk.fromPrivate(privatePem);
console.log(privateJwk);fromPrivateToPublic
This method converts a private PEM key to a public JWK. The private PEM key is passed as a parameter to the method, and the public JWK is returned.
The method works by first creating a temporary PEM file from the private PEM key and then using openssl to generate a public key from that file. The public key is then converted to a JWK using the fromPublic method.
Syntax
Pem2Jwk.fromPrivateToPublic<T>(privatePem: PEM, extraKeys?: T): Promise<PublicJWK<T>>Parameters
-
privatePem: The private PEM file. Can be a string or a Buffer. -
extraKeys(optional): An object that provides additional information to be included in the JWK.
Return Value
A Promise that resolves to the public JWK.
Example
const privatePem = `-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----`;
Pem2Jwk.fromPrivateToPublic(privatePem).then(publicJwk => {
console.log(publicJwk);
});
