Advice/help/better solution for checking whether a given string can be a valid IP address or not

Asked 2021-Jun-13 at 14:31

Honestly, I think the code which I've written is trash and I don't think it's the best way to solve the problem. I need a few suggestions or improvements to solve this problem. I'm still new to coding. Appreciate it if you can give some tips on how to work with strings and various string functions.

CONDITIONS FOR THE STRING TO BE AN IP ADDRESS:-

An identification number for devices connected to the internet. An IPv4 addresses written in dotted quad notation consists of four 8-bit integers separated by periods.

In other words, it's a string of four numbers each between 0 and 255 inclusive, with a "." character in between each number. All numbers should be present without leading zeros.

Examples:

192.168.0.1 is a valid IPv4 address
255.255.255.255 is a valid IPv4 address
280.100.92.101 is not a valid IPv4 address because 280 is too large to be an 8-bit integer (the largest 8-bit integer is 255)
255.100.81.160.172 is not a valid IPv4 address because it contains 5 integers instead of 4
1..0.1 is not a valid IPv4 address because it's not properly formatted
17.233.00.131 and 17.233.01.131 are not valid IPv4 addresses because they contain leading zeros

Here's my code (I know it's trash and doesn't make any sense):-

You had a lot of loose 47, 48, etc. values for things like '0'. Better to use the latter syntax.

There were a number of if range checks. Using some additional state variables can reduce the complexity.

Using inputString[i] everywhere is cumbersome. Better to do (e.g. int chr = inputString[i]; and use chr instead--it's simpler and easier to read).

ANSWER

Answered 2021-Jun-13 at 10:42

I think what's happening here is that you've put the container name before the environment argument list to the docker run command.

So instead of setting the PACT_BROKER_DATABASE_NAME and other environment variables for the running container with your custom values, they are simply being discarded by the runtime.

Try this instead:

Trying to blur highest variance point of an image but some conversion problem exist in code

Asked 2021-Jun-10 at 20:29

I am trying to blur of highest variance point from the image. I wrote code below. 1st part finds the variance of the image. I checked the resultant variance of an image and it is correct. (I used Lena's image) In 2nd part, I find the highest variance coordinates and send to this Function which finds gaussian blur. When I execute this code, it throws "C:\Tmp\blur_highest_variance.py", line 66, in sigma=15) numpy.core._exceptions.UFuncTypeError: Cannot cast ufunc 'subtract' output from dtype('float64') to dtype('uint8') with casting rule 'same_kind' I tried a few conversions between types but no avail. Can you show me some direction?

ANSWER

Answered 2021-Jun-10 at 18:48

The error message tells us the line and the reason for the error:

Traceback (most recent call last):
File "C:\Tmp\blur_highest_variance.py", line 66, in sigma=15)
numpy.core._exceptions.UFuncTypeError: Cannot cast ufunc 'subtract' output from dtype('float64') to dtype('uint8') with casting rule 'same_kind'

It is more simple to debug the code using intermediate variables:

QUESTION

Which encryption password does cryptography.fernet uses?

Asked 2021-Jun-10 at 19:40

I am making a program which encrypts and decrypts texts. I am using Python 3.7 and cryptography.fernet library. I want to enter some information about my program's encryption standard to the GitHub page but I didn't understand which encryption does Fernet uses.

Here is my sample code which I am used in my project. I want to encrypt with 256-bit (AES-256) key but the key which this code generates is longer than 32 characters. It's 44 characters. But in official web site of cryptography library it says this code generates 128-bit key. What is the name of this 44 character (352-bit) key? Or is there any way for 256-bit symmetric encryption without PyCrypto?

...

ANSWER

Answered 2021-May-03 at 13:26

It is well written in the documentation;

Implementation

Fernet is built on top of a number of standard cryptographic primitives. Specifically it uses:

AES in CBC mode with a 128-bit key for encryption; using PKCS7 padding.

HMAC using SHA256 for authentication.

Initialization vectors are generated using os.urandom().

For complete details consult the specification.

Therefore you cannot use AES-256 with Fernet

Cryptography.io library has other modes too, in the hazardous material layer including CBC, CTR, and GCM for AES-256, too.

PyCrypto can use a wide range of mode of operations for AES-256 including CBC, CTR, GCM, SIV, and OCB

Not clear how you get 44 bytes, here is the way to get the 32-bytes;

ANSWER

Answered 2021-Jun-08 at 10:00

Instead of adding the CRC to the image data, you may append the CRC to the end of the PNG file (as binary file).
Applications that read the new file (with few for bytes at the end) are going to ignore the redundant bytes.

Copy the content of download.png to bitadd_crc.png
Write the CRC (as two HEX digits or other format), to the end of bitadd_crc.png file.

The only difference of bitadd_crc.png and download.png is going to be the last two bytes.

Can I buy a single MAC address for a computer project?

Asked 2021-Jun-02 at 16:28

So, I'm currently building an 8-Bit computer, and working on getting it connected to the internet, clearly just on a simple LAN to start off, in the hope of making ARP requests and such like which would be pretty cool. I have had a little look around and I can only find standards companies selling MAC address by the million, this wont work for me.

Does anyone know how someone can accquire a single MAC address for personal use, not making money from it, but registered non the less.

Cheers all!

ANSWER

Answered 2021-Jun-02 at 16:28

Well one idea is that Microchip sells small EEPROM memory chips preprogrammed with a MAC address. One example of this is the AT24MAC602. It also contains a unique read-only 128-bit serial number and 2Kb (256 bytes) of user-accessible serial EEPROM NVM storage.

One way to use this would be to incorporate the chip into your design. Another would be to read out the MAC with an appropriate reader and hard code the address into your project.
