cryptography hashes

This function uses the cryptography library to sign a given message. It first loads the private key from a PEM file, then calculates the hash of the message, and finally signs the hash with the private key using the PKCS1v15 padding and SHA256 hash algorithm.

cryptography

This code example uses the AES algorithm and CFB mode from the cryptography library to encrypt and decrypt data. First, a random key is generated, and then the key is used to encrypt the data. During the encryption process, PKCS7 padding is used to ensure that the size of the data block is a multiple of the AES block size. The decryption process is the reverse of the encryption process.

Cryptography default_backend

This code defines a function that signs the given data using the provided private key. The function first generates a random initialization vector (IV), then pads the data with PKCS1v15 padding, and finally signs the padded data using the SHA256 hash algorithm and PKCS1v15 padding mode.
