I'm BIP38 curious, please help me out! April 06, 2015, 04:55:23 PM

Last edit: April 07, 2017, 07:09:13 AM by minimalB Merited by LoyceV (8) #1 Hey,



I'd like to figure out how fast BIP38 paper wallets could get cracked in case someone gets to them physically and tries to guess the password.



I created three BIP38 encrypted paper wallets with easy to crack passwords. Only small and capital English letters are used (from "a" to "Z", no numbers, no special characters). Say thanks when you get the money : )



I'll update this post with results when all three wallets are redeemed.



Happy cracking!
