You may be right, but i would guess that the key creation process will stay nearly the the same in alpha,beta and final version. I plan a package that will enable everybody to create this vouchers and as i am not a pro dev it will take some of my time. The key creation process will hopefully not change that much so it can be prepared now which will give me some more time for the graphics later on and i will be able to test my first results on the beta.
Actually we're considering one change, but I'll ansewer you on PM anyway
@ gimre thanks a lot, i don't want to hurry, pls. take your time
@ kodtycoon everything fine, tnx !

1. curve is secp256k1
2. public key is "compressed" (there's byte 02 or 03 byte used instead of encoding full Y, Y can be retrieved from X and that 02/03 byte)
encoding public key (PK):
1. d1 = sha3(PK)
2. d2 = ripe160(d1)
3. d3 = concat(version, d2), version byte for alpha is 0x98
4. chk = 4 first bytes of sha3(d3)
5. d4 = concat(d3, chk)
6. Base32encode(d4)
Perfect, that will help, thanks! Will the base32 use special alphabet? private key will be 32byte int? and is there already a wallet import format defined for the private key, will it be base32 or base58 encoded?
