I hereby claim:

To claim this, I am signing this object:

plaintext = The secret text (message, password, ...) you want to encrypt.
ciphertext = A plaintext that has been encrypted.
cipher = A mathematical function that takes at least a key and a plaintext and produces a ciphertext. For example: AES.
hash function = A mathematical function that produces a hash which cannot be reversed back to plaintext.
key = A secret key that allows someone to decrypt a ciphertext back into a plaintext.
secret = see key.

Legacy Code

Classical: Code that relates to something which is no longer supported.
Modern: (1) source code inherited from someone else and (2) source code inherited from an older version of the software.

(3) BOTH Trifecta

	// This kind of sucks because is relies on the window object which means the React will have issues being Isomorphic (rendered server side).
	// So if anyone has a better suggestion as to attaching to a global object and waiting for it to exist i'm all ears.
