I might throw up a bounty to do an "intermediate code generator" as well. (this won't be hard - just another simple recipe using scrypt,sha256,base58)

Here is what I imagine... another tab that says "Encrypted Wallets"

On the tab there would be two functions: generate intermediate code, and decrypt encrypted wallet

THe intermediate code takes a passphrase and makes a code (or series of codes) out of it. The code can be used by someone else to generate bip38-encrypted paper wallets without knowing the passphrase. Intermediate code generator takes a passphrase as input, and outputs a string that simply encodes 4 bytes of salt, 4 bytes of a combined "batch" and "sequence" number, and one compressed EC point. The EC point is G * sha256(scrypt(passphrase, salt, 16384, 8, 8 ) + batch+sequence bytes) or something substantially similar. The sequence number can be incremented to create more intermediate codes from the same passphrase without repeating the scrypt.

standardized encrypted paper wallets would be nice

Up next is the BIP38 stuff.

+1

higher resolution art would be nice. It's much too low for my taste.
