Please see https://github.com/Obvious/ursa for a maintained alternative to this module, which should do everything this does.
This module provides access to RSA public-key routines from OpenSSL.
Support is limited to RSAES-OAEP and encryption with a public key, decryption with a private key.
See test/test.js and test/getters.js.
This module should work on both Node.js 0.4.x and 0.6.x.
