this.keys but no opts means cookies don't get signed

[jergason]

In Cookie.prototype.set (https://github.com/expressjs/cookies/blob/2dcb71f130a7eaafd16e71b9af70debe11d4c93f/lib/cookies.js#L69), the signed variable is true if opts.signed or this.keys is truthy. However, the check for whether to sign keys or not also checks if opts exists.

This means that if this.keys is truthy, but opts is undefined, the signed variable will be true but the key still won't be signed. My expectation is they key should be signed if signed == true, and it shouldn't depend on the existence of opts.

That seems to make sense, though I'm not sure how easy this will be to fix without including it in the major version bump, because I wonder how many people have the keys set but no options given. I'll have to think about it some. Also input from @jonathanong

Ha was gonna remove that in the next major

Cool, that was my suspicion. It seems weird that the existence of keys caused cookies to automatically sign. So I would almost say that the current behavior is intended: you only get signed cookies if you sent {signed: true} to .set. Does that sound right @jonathanong ?

Current behavior is intended :( I wanted the next version to have .sign() and .encrypt() as separate methods
