#### jwkToPem(Object jwk[, Object options]) -> String

The first parameter should be an Object representing the jwk, it may be public
or private. By default, either of the two will be made into a public PEM. The
call will throw if the input jwk is malformed or does not represent a valid
key.

##### Option: private Boolean _(false)_

You may optionally specify that you would like a private PEM. This can be done
by passing true to the private option. The call will throw if the necessary
private parameters are not available.
