nodeCrypto will throw an error if encryptionKey is undefined: https://github.com/elastic/node-crypto/blob/master/src/crypto.ts#L37

This will type guard the parameter.

throw new Error('Encryption Key required.');
}

return nodeCrypto({ encryptionKey });

nit: Any chance we can update the types for node-crypto to allow decrypt to accept a generic argument, like the old interface supported?

decrypt<T>(valueToDecrypt: string, aad?: string): Promise<T>;

@legrego we actually had a heated discussion about the same in the node-crypto repo but we decided not to do so for a reason:
The valueToDecrypt is not validated in any way before decryption (apart from the fact that it's a string when encrypted). It means that we have no control over the output of the decrypt method.
i.e.: You might be expecting the decrypted value to be a string, but that doesn't stop anyone to provide a valueToDecrypt that gets decrypted into anything else (string[], object, boolean, ...).
In my opinion, accepting a generic argument would allow (and encourage) devs to set the expected output, defeating the purpose of TS as a best practice advisor. With the current implementation (no generic argument), TS reminds you might get an unexpected output and you should implement type-guards. If you are sure about the exact output because you have full control over the input, you can cast it.

Thanks for the explanation @afharo!
