SQL Server Authentication cracking

Ok guys this is what I'm trying to do:
The username and password used for this example is sa/password.

The algorithm to encrypt the password is simply to expand every byte of the password to 2 bytes, swap the higher and lower 4 bits within each byte, xor each byte with A5. For example to encrypt the character "p":

(ASCII is 70 hex):
70 is expanded to 70 00
After the swap the result is: 07 00
XOR with A5: A2 A5

Hence to decrypt it, we will take the odd bytes, XOR with A5, and swap the higher and lower 4 bits.
Take A2
XOR with A5: A2 XOR A5 = 07
Swap: 7 becomes 70.

Hope that explains that, here is how I'm trying to do it.

sList = []
def main():
    #Get every byte of password and load it into a linked list, drop the odd numbered bytes (should be A5)
    password = ENCRYPTED()
    dropA5Bytes(password)
   
    xorThroughList(password, "a5") #the input password data and A5 converted to decimal   
    #XOR with A5
    reverseListItems(password)#
    #Reverse the order of each item in linked list
    printLinkedList(password)#
#Print linked list
#
#Convert linked list contents into text
    convertLinkedPassword(password)
#Print linked list
    printLinkedList(password)
def dropA5Bytes(sList):
    while (sList.count("a5") != 0):
        sList.remove("a5")

def xorThroughList(sList, key):
    for i in range(len(sList) - 1):
        sList[i] = str(int(sList[i], 16) ^ int(key,16)).zfill(2)

def reverseListItems(sList):
    for i in range(len(sList) - 1):
        sList[i] = sList[i][1] + sList[i][0]

def printLinkedList(password):
    print(password)
   
def convertLinkedPassword(password):
    for i in range(len(sList) - 1):
        sList[i] = chr(int(sList[i],16))
       
   
def ENCRYPTED():
    return ["b1","a5","93","a5","e2","a5","f6","a5","c6","a5","b6","a5","11","a5","f3","a5","32","a5","4d"]
   
main()

Oh yeah. it doesn't work right here is my output

['02', '45', '17', '38', '99', '91', '81', '68', '51', '4d']
['02', '45', '17', '38', '99', '91', '81', '68', '51', '4d']
The first should be the decrypted password in hex
the second should be in ascii.  It's not.. and the password isn't right either.

What does /prog/ think?

I think you need to sage this bullshit, stat.
