What is RippleWarpWallet
You can find it here: https://termhn.github.io/ripplewarpwallet
RippleWarpWallet is a fork of the original WarpWallet used for making Ripple wallets instead of bitcoin ones. It is a deterministic ripple address generator. You never have to save or store your secret key anywhere. Just pick a really good passphrase - I recommend using Diceware, an online implementation of which you can find here - and never use it for anything else.
This is not an original idea. bitaddress.org's brainwallet is the original inspiration, and the original WarpWallet of course inspired this Ripple version. The source code is hosted on github.
WarpWallet adds two improvements over the traditional brainwallet:
(1) WarpWallet uses scrypt to make address generation both memory and time-intensive. And
(2) you can "salt" your passphrase with your email address. Though salting is optional, we recommend it. Any attacker of WarpWallet addresses would have to target you individually, rather than netting you in a wider, generic attack. And your email is trivial to remember, so why not?
If you're a programmer and want to implement WarpWallet yourself, here is the algorithm used. Ripple-specific functions are part of the ripple-keypairs npm package...
s1 = scrypt(key=(passphrase||0x1), salt=(salt||0x1), N=218, r=8, p=1, dkLen=32)
s2 = pbkdf2(key=(passphrase||0x2), salt=(salt||0x2), c=216, dkLen=32, prf=HMAC_SHA256)
secret = generateSeed(s1 ⊕ s2)
keypair = deriveKeypair(secret)
address = deriveAddress(keypair.publicKey)
