            How to generate a byte string consisting of random nonzero bytes using Python?
            Asked 2022-Jan-30 at 23:40

            As part of implementing the PKCS #1 v1.5 padding scheme for RSA, I need to generate an octet string of length n consisting of pseudo-randomly generated nonzero octets. I'm looking for the best way to do this using Python.

            You mentioned my previous question here.

            I just faced the same issue as you on Colab. It is 100% issue with libraries.

            Initially, I got the error for SMOTE:

            • `AttributeError: 'SMOTE' object has no attribute '_validate_data'

            After installing/reinstalling libraries I got exactly your error.

            How did I resolve it?

            • Started to run Colab and imported all common libraries (pd, np, scikit, etc).
            • Installed PyCaret via pip install. Then import pycaret and from pycaret.classification import *
            • Colab reacted: you have issues with scipy, sklearn, lightgbm, please restart your runtime.
            • Restarted my runtime on Colab
            • Imported all libraries again as I did in step 1
            • Ran import pycaret and from pycaret.classification import * only

            This question is the inverse of the existing one here: Encrypt in python 3.7 and decode in NODEJS 12 .

            I would prefer to use the exact equivalent of tweet-nacl on python but that project says it is old and not recommended https://github.com/warner/python-tweetnacl . Their recommended replacement is https://github.com/pyca/pynacl : but that one is an interface to libsodium not tweet-nacl and there is no clear documentation on how to achieve the decryption.

            I just found out that the problem was in the MySQL Datatype.

            • BLOB: Can handle up to 65,535 bytes of data.

            • MEDIUMBLOB: The maximum length supported is 16,777,215 bytes.

            Changing the datatype to MEDIUMBLOB in my DB makes everything work ok.

            This is how I am decrypting encrypted_bytes_database and reading this .csv file as a pandas df.

            Web cryptography implement HKDF for the output of ECDH
            Asked 2021-Jun-13 at 11:02

            I want implement a elliptic curve diffie hellman using HKDF as key derivation function. I am using a python backend and (vanilla) javascript in frontend. I am using python cryptography library in backend and Web Crypto api in frontend as cryptographic library. I created ECDH key pair in both side and exchanged the pbulic keys. Now I am trying to create the AES shared key with the exchanged public key and private key along with HKDF algorithm. I am able to do it in the python backend (I followed this example for the python code):

            ...

            ANSWER

            Answered 2021-Jun-13 at 11:02

            The referenced Python code uses P-384 (aka secp384r1) as elliptic curve. This is compatible with the WebCrypto API, which supports three curves P-256 (aka secp256r1), P-384 and P-521 (aka secp521r1), see EcKeyImportParams.

            The following WebCrypto code generates a shared secret using ECDH and derives an AES key from the shared secret using HKDF. In detail the following happens:

            • To allow comparison of the derived key with that of the referenced Python code, predefined EC keys are applied. The private key is imported as PKCS#8, the public key as X.509/SPKI. Note that due to a Firefox bug concerning the import of EC keys, the script below cannot be run in the Firefox browser.
            • After the import the shared secret is created with ECDH using deriveBits() (and not deriveKey()).
            • The shared secret is imported with importKey() and then the AES key is derived using HKDF, again with deriveBits().

            InvalidSignature with python cryptography

            I want to verify a signature of some payload, given a public ECDSA key, and I know beforehand that the signature is correct. I want to use the cryptography python library, but the problem being, I can't make the verification work and always get a InvalidSignature exception, even though the signature should be correct.

            Here the code snippet I'm currently using. The public key is base64 encoded and in DER format (so no ---BEGIN PUBLIC KEY --- etc.) and the signature is base64 encoded as well. The message is some JSON data as a string, with no spaces.
