Question

我正在为Wikipedia的MD5哈希算法实现伪代码。它包括几个称为“ leftrotate”的操作，我指的是“向左移动”。但是，当我实现代码时，一切似乎都可以进行，直到向左移动为止。我不确定这是否是此实现的正确选择，我不确定是怎么做的以获取错误，或者我什至无法正确实现此实现。

# Process the message in successive 512-bit chunks:
binaryArray = [binary[i:i+512] for i in range(0, len(binary), 512)]
for chunk in binaryArray:
    M = [int(chunk[i:i+32]) for i in range(0,len(chunk),32)]
    A = a0
    B = b0
    C = c0
    D = d0

    for i in list(range(0,64)):
        if i >= 0 and i <= 15:
            F = (B&C)|((~B)&D)
            g = i
        elif i >= 16 and i <=31:
            F = (D&B)|((~D)&C)
            g = (5*i+1)%16
        elif i >= 32 and i <= 47:
            F = (B^C)^D
            g = (3*i+5)%16
        elif i >= 48 and i <= 63:
            F = C^(B|(~D))
            g = (7*i)%16
        F = F + A + K[i] + M[g]
        A = D
        D = C
        C = B + (F<<s[i]) #This is where the error occurs
    a0 = a0 + A
    b0 = b0 + B
    c0 = c0 + C
    d0 = d0 + D

预期：包含明文字符串的MD5哈希的输出文件

获取：错误或输出文件为空

哈希实现上的TypeError
