Python generates a pair of RSA keys and saves the public and private keys as .pem files respectively. Use the public key in the generated RSA key pair to encrypt the data, and then use the private key to decrypt. Convert RSA’s public key exponent (E) and modulus (N) to .pem format
You can use the cryptography library to generate a pair of RSA keys and save the public and private keys as .pem files respectively. Here is a sample code: from cryptography.hazmat.backends import default_backend from cryptography.hazmat.primitives import serialization from cryptography.hazmat.primitives.asymmetric import rsa # Generate RSA key pair private_key = rsa.generate_private_key( public_exponent=65537, key_size=2048, backend=default_backend() ) # Get […]

One Demo handles the front-end and back-end multi-part uploading of large files, resumed uploading at breakpoints, and instantaneous uploading.
1Foreword File uploading is very common in project development. Most projects will involve the uploading of pictures, audios, videos, and files. Usually a simple Form can upload small files, but when encountering large files, such as more than 1GB, or When the user’s network is relatively slow, simple file upload is not applicable. The user […]
