10	10		Link Lock is a tool for encrypting and decrypting URLs. When a user visits an
11	11		encrypted URL, they will be prompted for the password. If the password is
12		-	correct, Link Lock decrypts the original URL and redirects them. Otherwise, an
13		-	error is displayed.
	12	+	correct, Link Lock decrypts the original URL and redirects there. Otherwise, an
	13	+	error is displayed. If a hint is added, it is displayed right above the
	14	+	password prompt.
	15	+
	16	+	Link Lock has many uses:
	17	+
	18	+	- Store private bookmarks on a shared computer
	19	+	- Encrypt entire web pages (via [URL
	20	+	Pages](https://github.com/jstrieb/urlpages))
	21	+	- Send sensitive links over public or insecure channels (e.g., posting links
	22	+	to a public website that require a password to access)
	23	+	- Simple CAPTCHAs – particularly effective against basic web scrapers that do
	24	+	not respect `robots.txt`
	25	+	- Add a password to shared Dropbox or Google Drive links

	42	+
	43	+	- I am a college student, not a security professional – there may be
	44	+	best-practices I am not aware of.
	45	+	- Once someone decrypts a link, they can share the original URL as much as they
	46	+	want. Only share encrypted links with trusted people.
	47	+	- I am not comfortable using JavaScript, and I don't have a firm grasp of the
	48	+	nuances of the language – there may be bugs that I don't even know to check
	49	+	for.
	50	+	- This is the first project I have ever done using encryption – there is likely
	51	+	a subtle mistake somewhere.
	52	+	- Most of the encryption/decryption code is based on [MDN
	53	+	tutorials](https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/deriveKey#PBKDF2_2)
	54	+	for the `SubtleCrypto` API
