这段代码看起来是使用RSA加密算法生成密钥对，并进行信息加密的过程。以下是代码的完善建议：

1. 导入所需的模块和函数：

   from Crypto.Util.number import getPrime, inverse, getRandomRange
   from Crypto.PublicKey import RSA
   import base64

2. 修改 `long` 函数为 `int`：

   key = RSA.construct((int(n), int(e), int(d), int(p), int(p)))

3. 将 `xrange` 替换为 `range`（Python 3.x 不再支持 `xrange`）：

   for _ in range(s):

4. 修改打印语句中的 `enc.encode('base64')` 为 `base64.b64encode(enc)`：

   print(base64.b64encode(enc))

完成这些修改后，代码应该如下所示：

from Crypto.Util.number import getPrime, inverse, getRandomRange
from Crypto.PublicKey import RSA
import base64
from secret import s, FLAG

def gen_prime(s):
    while True:
        r = getPrime(s)
        R = [r]
        t = int(5 * s / 2) + 1
        for i in range(0, t):
            R.append(r + getRandomRange(0, 4 * s ** 2))
        p = reduce(lambda a, b: a * b, R, 2) + 1
        if isPrime(p):
            if len(bin(p)[2:]) == 1024:
                return p

while True:
    p = gen_prime(s)
    q = gen_prime(s)
    n = p * q
    e = 65537
    d = inverse(e, (p-1)*(q-1))
    if len(bin(n)[2:]) == 2048:
        break

msg = FLAG
key = RSA.construct((int(n), int(e), int(d), int(p), int(p)))
for _ in range(s):
    enc = key.encrypt(msg, 0)[0]
    msg = enc

print(key.publickey().exportKey())
print('-' * 76)
print(base64.b64encode(enc))
print('-' * 76)

请注意，这只是对代码进行了一些基本的修正和完善，还可能存在其他需要优化的地方。
