DSA uses public-key cryptography. We need to first generate a DSA key pair that consists of a public key and a private key. The private key needs to be kept secret and the public key can be shared with others. We create a DSA signature using the private key and verify...

We can use the PyCryptodome module to generate RSA keys and encrypt and decrypt data using the generated RSA keys. We can also export the public key and the private key to files and import the keys from the files. Using the PyCryptodome module, we can generate RSA...

Using the RSA module of PyCryptodome one can encrypt and decrypt data easily using Python. RSA uses public-key cryptography. Using RSA one can generate a key pair consisting of a private key and a public key. The private key needs to be kept secret while the public...

We can encrypt and decrypt an image easily using the PyCryptodome module in Python. In this article, we would use the AES encryption algorithm in the CBC mode to encrypt an image. We would generate the key and the Initialization Vector (IV) randomly. And then, we...

In this article, we would discuss how to encrypt and decrypt files using Python. We would take a file name as input, encrypt it and store it in an output file. Also, we would generate a secret key securely and store the secret key in a file. Later, we would read that...
