Package Exports

rsa-pem-from-mod-exp
rsa-pem-from-mod-exp/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (rsa-pem-from-mod-exp) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

node-rsa-pem-from-mod-exp

Create RSA Public Key PEM from Modulus and Exponent value in node.js. There are no dependencies to other modules for use.

This allows you to use the modulus/exponent values for validating signed value.

The original code is based on the answer to this stackoverflow question.

Install

npm install rsa-pem-from-mod-exp

Usage

//getPem = function(modulus_base);
var getPem = require('rsa-pem-from-mod-exp');

//modulus should be a base64/base64Url string
var modulus =  "niqcAxl7LclB0kE6q9AcAd8EE+0W6AsriR9Fs9T+6QVXl8uiCiAbh/KCyy8X8C2bHsFpNBvwGTqMwHbqZqWBVUvYRtfCFcy3Xmertb09DnOBeWqKS4181kss97JDO6G07QNbuLSWwkkO82CHD1kUmeF5/dof0Ra6bsRXqppdo86NzlgFud+E2s5BM3XwewZVSpA69bwEiXaRDhrsg5mqeOm68VyxE8LQu+895kKsBnTvTueZTrXT+HNaIveoYe8+Lb7b/mZYtlhrDK0i/8EDox85vxnzKZ7wNswqqcDg6vfC2911phSTPh13jv2FIOkjO/WHhHEzRnS2VQqivqIbsQ";

//exponent should be base64/base64url
var exponent = "AQAB";

var pem = getPem(modulus, exponent);

In the above example pem will now contain the following string.
