Is there a chance to get the same key with different data and is it possible to crack the key?

Question

Cryptography

Is it possible that using this algorithm you can get two identical keys, but with different data? And if so, what is the likelihood of that? And is it possible to crack the key?

import random

def _gen_salt(msg):
    salt = 0
    for x in msg:
        salt = ord(x) ** len(msg)
    salt = salt + salt - len(msg) * salt
    return salt

def _crypt(msg, bits=64):
    # Stage 1 string
    enc = ""
    # Stage 2 string
    val = ""

    # Salt
    salt = _gen_salt(msg)
    # Key
    key = random.randint(12, 1247)

    # Stage 1
    for c in msg:
        val = 500 - ord(c)
        # IDK how it works, just random operators
        val = str(hex(int(
            salt * val + val - key * key ^ key ** val * val
        )))
        enc += val[3:][:128] + "-"

    # Stage 2
    for x in enc.split("-"):
        if x:
            val += str(hex(int(
                int(x, 16) * salt * key % key
            )))

    # Parse encrypted string
    val = val.replace("0", "").replace("x", "")
    val = val[::2] + val
    val = val[:128] + val[:512:salt - key]
    val = val[::3] + val[::2] + val

    # Fix size
    if len(val) < bits:
        pos = 1
        while len(val) < bits:
            if len(val) >= bits:
                break
            val += val[::pos]
            pos += 1
            if pos > 100:
                pos = 1

    # Return encrypted string
    return val[:bits] + val[:bits:2]

def crypt(msg, bits=128):
    # Encrypt string and fix string length, if possible
    enc = _crypt(msg, bits).replace("-", "")[:bits]
    return enc, len(enc)

PS Please do not yell about my code.
