python - Python 中的 XRP Warp 钱包

Question

我想用 Python 实现Ripple Warp 钱包。我能够成功生成一个地址，但它与网站输出不匹配。

这是我的代码：

from Crypto.Protocol.KDF import PBKDF2
from Crypto.Hash import HMAC, SHA256
import binascii
import scrypt
from xrpl.core import keypairs


def hmac_sha256(secret, salt):
    m = HMAC.new(secret, None, SHA256)
    m.update(salt)
    return m.digest()


def sxor(s1,s2):
    return ''.join(chr((a) ^ (b)) for a,b in zip(s1,s2))


def generate_keypair(passphrase, salt=""):
    # s1 = scrypt(key=(passphrase||0x1), salt=(salt||0x1), N=2^18, r=8, p=1, dkLen=32)
    s1 = scrypt.hash(passphrase.encode() + b"\x01", salt.encode() + b"\x01", 1 << 18, 8, 1, 32)
    print("S1: ",s1)

    # s2 = pbkdf2(key=(passphrase||0x2), salt=(salt||0x2), c=2^16, dkLen=32, prf=HMAC_SHA256)
    s2 = PBKDF2(password=passphrase.encode() + b"\x02",salt=salt.encode() + b"\x02",
        dkLen=32, count=1 << 16, prf=hmac_sha256)
    print("S2: ", s2)
    return binascii.hexlify(sxor(s1,s2).encode())


def getXRPAddress(passphrase, salt):
    # Use Warp Wallet algorithm to generate seed
    rawSeed = generate_keypair(passphrase,salt)
    # Generate Address with xrpl-py
    seed = keypairs.generate_seed(entropy=rawSeed.decode())
    public, private = keypairs.derive_keypair(seed)
    pk = keypairs.derive_classic_address(public)
    return pk


pk = getXRPAddress("helloworld",salt="")
print("Public Key:")
print(pk)
# returns: r4P69jspBpGvTcKQJf1XLRojZGWWjvop9c
# should be: r4LuZGjbLfrgNG59wcvNSeWF5EH5NiaiQZ

• 注意：这主要基于需要更新到 Python 3的脚本。

脚本输出为：r4P69jspBpGvTcKQJf1XLRojZGWWjvop9c

网站输出为：r4LuZGjbLfrgNG59wcvNSeWF5EH5NiaiQZ

我有什么问题或者我需要调整什么以匹配网站输出吗？
