PyCrypto for AES encryption (the link you posted actually uses this). Pillow for image processing. You may install both libraries via Python’s pip package manager. cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests, and key derivation AES or Advanced Encryption Standard is encryption algorithm based on the Rijndael cipher developed by the Belgian cryptographers, Joan Daemen and Vincent Rijmen. The Advanced Encryption Standard (AES) specifies a FIPS-approved cryptographic algorithm that can be used to protect electronic data. The AES algorithm is a symmetric However, AES-CTR can be used securely in combination with other cryptographic Let C and T be the outputs that result from performing the Authenticated Encryption Function AES (acronym of Advanced Encryption Standard) is a symmetric encryption algorithm.
