Key exchange

[richardschneider]

Problem

As a key holder
I want to exchange the key with other systems
So that they can use the same key

Solution

Most other systems will accept a key in PKCS #8 or PCKS #12 format. Both formats allow encrypting with a password, which should be enforced.

PKCS #8 is a natural choice, because PKCS #12 requires a certificate which is not currently supported. PEM encoding (text not DER) is preferred.

Design

• Every private key class implements export ([format], password).
• keys implements import (data, [format], password).

Where format defaults to pkcs-8.

This allows libp2p/js-libp2p-keychain#7 to create and save keys using this library.

@diasdavid Have you looked at jsrassign. It has PKCS 7 and 8 support.

@richardschneider I never tried it out, but looks like it has what you need and it is CJS
