I tried to generate a public key and a private key by using RSA 2048, then send the public key as hex to a destination. However, I faced a problem, the generated public key size is greater than 2048 bit. I used the following script. Could I know why the key size is greater than 2048 bit?
WebAPI principles¶. Asymmetric keys are represented by Python objects. Each object can be either a private key or a public key (the method has_private() can be used to distinguish them).. A key object can be created in four ways: generate() at the module level (e.g. Crypto.PublicKey.RSA.generate()).The key is randomly created each time.
