crypto.publicDecrypt doesn't seem to work

pub doesn't work. Only priv and bob.publicKey but I know that priv should work because in docs: Because RSA public keys can be derived from private keys, a private key may be passed instead of a public key. I really want to know why pub isn't working.

It's showing that:

@tniessen Is that an oversight? The 'private' here looks wrong to me:

node/lib/internal/crypto/cipher.js

Lines 68 to 69 in c80771d

	const publicDecrypt = rsaFunctionFor(_publicDecrypt, RSA_PKCS1_PADDING,
	'private');

Since that means preparePrivateKey() is called, not preparePublicOrPrivateKey().

@bnoordhuis I think so, yes. I am surprised it went unnoticed for so long, but it is probably a rarely used function.
