it fixes the issue About the ArrayIndexOutOfBounds
Your problem seems to be that when the input ends with ;, the 5th element gets discarded. For example:

code :

"abc;def;".split(";")  ->  ["abc", "def"]

"abc;def;".split(";", 3)  ->  ["abc", "def", ""]

"abc;def;".split(";", -1)  ->  ["abc", "def", ""]

String price;
if (values[3].startsWith("EUR ") || values[3].endsWith(" €")) {
    // ignore non-digits and non-commas, and replace commas with dots
    price = values[3].replaceAll("[^\\d,]", "").replaceAll(",", ".");
} else {
    // ignore non-digits and non-dots
    price = values[3].replaceAll("[^\\d.]", "");
}

File corrupt after BinaryRead/Write / FileStream.Read/Write /File.Read/WriteAllBytes

it helps some times Your encryption method is not invertible, and so you cannot reliably decrypt a general binary message with it. The problem occurs because it is possible for two different plaintext values to encrypt to the same ciphertext value, and when this happens there's no way for you to determine when decrypting which was the correct input value.
Example:

code :

if inByte = 100 and keyByte = 100:
    ApplyVernam(100, 100) = 100

if inByte = 0, keyByte = 100:
    ApplyVernam(0, 100) = 100

this.ResBytes[x] = this.ApplyVernam(this.FileBytes[x], this.FileBytes[1]);

this.ResBytes[x] = x == 1 ? this.FileBytes[x] : this.ApplyVernam(this.FileBytes[x], this.FileBytes[1]);

Read pattern from file and write to another file using python

should help you out You can use this regular expression, assuming all functions start on their own line (function SomeName()\n) and end on a new line (\n}), as in your example:

code :

import re

with open('file.js', 'r') as f:
    content = f.read()

functions = re.findall(r'(function\s.+?\(.*?\)\n.+?\n\})', content, re.DOTALL)
for i, func in enumerate(functions):
    with open('func{}.js'.format(i), 'w') as f:
        f.write(func)

function Script1(){
  var player = GetPlayer();
}

Read file, find pattern, edit and write back to same binary file

By : user2861356

Date : March 29 2020, 07:55 AM

may help you . I am trying to read a file which has several lines of data, modify one of the lines and write back the edits into the same file I read from. , Use this to modify according to pattern:

code :

import re
from os import rename

path = r'/path/to/binary'
tmp_file = path + r'.mod'

pattern = b'\x55\x4F\x50\x44\x01\x00\x00\x00\x00\x00\x00\x00\x00\x06\x05\x08\x07'
new_pat = b'\x55\x4F\x50\x44\x01\x00\x00\x00\x00\x00\x00\x00\x00\x06\x05\xde\xad'

myre = re.compile(pattern)
with open(path, 'rb') as read_file, open(tmp_file, 'wb') as write_file:
    write_file.write(myre.sub(new_pat, read_file.read()))

rename(tmp_file, path)

import struct
from collections import defaultdict
from os import rename

path = r'/tmp/rando_bin'
tmp_file = path + r'.mod'

location_start_hex = 0
location_end_hex = 8
fill_value = 0

mapper = defaultdict(set)
for hex_location in range(location_start_hex, location_end_hex + 1):
    mapper[hex_location // 2].add('right' if hex_location % 2 else 'left')


with open(path, 'rb') as read_file, open(tmp_file, 'wb') as write_file:
    byte_cnt = 0
    x = read_file.read(1)

    while x:
        if byte_cnt in mapper:
            if len(mapper[byte_cnt]) == 2:
                write_file.write(bytearray([fill_value]))
            elif 'left' in mapper[byte_cnt]:
                y = struct.unpack('B', x)[0]
                new_byte = y & int('00001111', 2)
                write_file.write(bytearray([new_byte]))
            else:
                y = struct.unpack('B', x)[0]
                new_byte = y & int('11110000', 2)
                write_file.write(bytearray([new_byte]))
        else:
            write_file.write(x)
        byte_cnt += 1
        x = read_file.read(1)

rename(tmp_file, path)
