QUESTION
I'm generating a digital signature(using https://pypi.org/project/rsa/) and saving it on a qrcode(using https://pypi.org/project/qrcode/) so I can distribute them on paper and scan them later. However, the byte sequence scanned is different from the one i originally created, why the verification fails.
The following code
...ANSWER
Answered 2022-Mar-29 at 06:25- I would highly recommend that you encode whatever you want to sign in base64 before signing. This is a standard approach for digital signatures, ensuring consistency of the signed data.
- The output of the pyzbar.decode function is an array of "Decoded" objects, of which you're not retrieving the correct element.
Below the corrected code:
QUESTION
I am going over the description of Sha-512. It is mentioned that the initial hash value consists of the sequence of 64-bit words that are obtained by taking the fractional part of the first eight primes. I am trying to replicate these values in Python, but I am not getting the same results. To include more digits, I am using the mpmath library.
...ANSWER
Answered 2022-Mar-08 at 21:38As a comment already explained, you're actually only using 53 bits in your calculations (native CPython float precision).
Here's an easy way to reproduce the result you're apparently after:

I was really hoping to allow existing users on our Rails app (6.0.4.1) that is currently using Authlogic (6.4.1) to be able to log in using existing passwords when we migrate to Devise (4.8.1).
Every article that I've seen has a nice explanation of how to do it IF the encryption is SHA-512. In those cases you modify config/initializers/devise.rb and setting config.encryptor = :authlogic_sha512 (source: https://gist.github.com/rpheath/8343779).
However, at some point our app moved from SHA-512 to SCRYPT by doing the following in order to transition users smoothly:
...ANSWER
Answered 2022-Feb-04 at 20:04Per https://github.com/heartcombo/devise/issues/3779, use devise-scrypt.
The common solution for this still seems to be using the devise-encryptors and devise-scrypt gems which means a number of additional of moving parts.
Yes, Devise supports other encryptors via extensions, that's the way to go. -José Valim

Looking at migrating all shiro hashed passwords to spring security hashed passwords (using Pbkdf2PasswordEncoder)
So far, what I'm looking at is reconstructing the shiro hash into proper format for spring password encoder to match successfully.
Taking a sample shiro hash:

Answered 2022-Jan-31 at 18:01The reason is that Spring Security does not include the algorithm and rounds in the hashed value.
You can keep the same hash by implementing your own encoder like so:

i have a Strimzi kafka cluster, deployed using the following yaml. LoadBalancer is enabled on port 9094, without TLS
I've a KafkaTopic created, and when i try to produce to the Topic on port 9094, it gives TopicAuthorization exception.
...ANSWER
Answered 2022-Jan-31 at 09:29None of your listeners has enabled authentication. So when you connect to it, you are just authenticated as ANONYMOUS. And ANONYMOUS has no ACLs, so it is not allowed to do anything. So you either need to enable authentication and use it or you need to disable the authorization. You should also always check the broker logs where you get the full authroization error with all details and make it more clear what the issue is.

QUESTION
I am trying to sign a pdf document from a 3rd party signature provider. I send them the document hash, after creating the empty signature and they send a timestamp token (we agreed it would be a timestamp signature) and I add the signature back into the pdf. the api call to get the timestmp and crl and ocsp goes well, but once I generate the pdf with the signature, adobe says the signature is not valid and the error is:
Error during signature verification.
Signature contains incorrect, unrecognized, corrupted or suspicious data. Support Information: SigDict /Contents illegal data
