Package Exports

node-rsa
node-rsa/src/libs/jsbn

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 (node-rsa) 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

Node.js RSA library
Based on jsbn library from Tom Wu http://www-cs-students.stanford.edu/~tjw/jsbn/

Pure JavaScript
No needed OpenSSL
Generating keys
Supports long messages for encrypt/decrypt
Signing and verifying

Installing

npm install node-rsa

Testing

npm test

Usage

Create instance

var NodeRSA = require('node-rsa');

var key = new NodeRSA([key], [options]);

key - parameters of a generated key or the key in PEM format.
options - additional settings

signingAlgorithm - algorithm used for signing and verifying. Default 'RSA-SHA256'

"Empty" key

var key = new NodeRSA();

Generate new key 512bit-length and with public exponent 65537

var key = new NodeRSA({b: 512});

Load key from PEM string

var key = new NodeRSA('-----BEGIN RSA PRIVATE KEY-----\n'+
                      'MIIBOQIBAAJAVY6quuzCwyOWzymJ7C4zXjeV/232wt2ZgJZ1kHzjI73wnhQ3WQcL\n'+
                      'DFCSoi2lPUW8/zspk0qWvPdtp6Jg5Lu7hwIDAQABAkBEws9mQahZ6r1mq2zEm3D/\n'+
                      'VM9BpV//xtd6p/G+eRCYBT2qshGx42ucdgZCYJptFoW+HEx/jtzWe74yK6jGIkWJ\n'+
                      'AiEAoNAMsPqwWwTyjDZCo9iKvfIQvd3MWnmtFmjiHoPtjx0CIQCIMypAEEkZuQUi\n'+
                      'pMoreJrOlLJWdc0bfhzNAJjxsTv/8wIgQG0ZqI3GubBxu9rBOAM5EoA4VNjXVigJ\n'+
                      'QEEk1jTkp8ECIQCHhsoq90mWM/p9L5cQzLDWkTYoPI49Ji+Iemi2T5MRqwIgQl07\n'+
                      'Es+KCn25OKXR/FJ5fu6A6A+MptABL3r8SEjlpLc=\n'+
                      '-----END RSA PRIVATE KEY-----');

Also you can use next methods:

key.generateKeyPair([bits], [exp]);
key.loadFromPEM(pem_string);

bits - key size in bits. 2048 by default.
exp - public exponent. 65537 by default.

Export keys

key.getPrivatePEM();
key.getPublicPEM();

Test key

key.isPrivate();
key.isPublic([strict]);

strict - if true method will return false if key pair have private exponent. Default false.

Encrypting/decrypting

key.encrypt(buffer, [encoding], [source_encoding]);

Return encrypted data.
buffer - data for encrypting, may be string, Buffer, or any object/array. Arrays and objects will encoded to JSON string first.
encoding - encoding for output result, may be 'buffer', 'binary', 'hex' or 'base64'. Default buffer. source_encoding - source encoding, works only with string buffer. Can take standard Node.js Buffer encodings (hex, utf8, base64, etc). 'utf8' by default.

key.decrypt(buffer, [encoding]);

Return decrypted data.
buffer - data for decrypting. Takes Buffer object or base64 encoded string.
encoding - encoding for result string. Can also take 'buffer' for raw Buffer object, or 'json' for automatic JSON.parse result. Default 'buffer'.

Signing/Verifying

key.sign(buffer, [encoding], [source_encoding]);

Return signature for buffer. All the arguments are the same as for encrypt method.

key.verify(buffer, signature, [source_encoding], [signature_encoding])

Return result of check, true or false.
buffer - data for check, same as encrypt method.
signature - signature for check, result of sign method.
source_encoding - same as for encrypt method.
signature_encoding - encoding of given signature. May be 'buffer', 'binary', 'hex' or 'base64'. Default 'buffer'.
