Answer 1

This is not supported natively by Node.js version v0.11.13 or below, but it seems that next version of Node.js (a.k.a v0.12) will support this.

Here is the clue: https://github.com/joyent/node/blob/v0.12/lib/crypto.js#L358

See crypto.publicEncrypt and crypto.privateDecrypt

Here is the future documentation for this https://github.com/joyent/node/blob/7c0419730b237dbfa0ec4e6fb33a99ff01825a8f/doc/api/crypto.markdown#cryptopublicencryptpublic_key-buffer
