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...

We can use Fernet from the cryptography module in Python to encrypt and decrypt data securely. The Fernet module uses a symmetric-key encryption algorithm to encrypt and decrypt data. So, if we use a secret key to encrypt plaintext, we would need to use the same...

bcrypt is a password hash function using which one can hash passwords. The bcrypt algorithm is based on Blowfish cipher and it incorporates a salt while hashing a password. Moreover, bcrypt is an adaptive function. It uses several iterations while hashing a password....
