To complement the evaluation of the encrypted data, the Lena image is coded and its metrics are compared with those reported in the literature, yielding some useful results. It is shown that the pseudo-random sequences produced by the cryptographic key generator have acceptable properties with respect to randomness, which are validated in this paper using National Institute of Standards and Technology (NIST) statistical tests. Also, it is applied to a simulated electrical energy consumption signal and implemented on a prototype, using low hardware resources, to measure physical variables hence, the unpredictability degree was statistically analyzed using the resulting cryptogram. You can also use it to encrypt a phrase with RSA, AES-256, or One Time Pad algorithm, to compute text, file, or folder hash values, and to securely shred files and folders. It is basically a free software to encrypt files and folder with AES-256 encryption. Moreover, the algorithm exploits dynamic simplicity and synchronization to generate encryption sub-keys using unpredictable seeds, extracted from a chaotic zone, in order to increase their level of randomness. Hyper Crypt is a free portable RSA key generator for Windows. In this work, a pseudo-random cryptographic generator algorithm with a symmetric key, based on chaotic functions, is proposed.

These chaotic systems encode information to obviate its orbital instability and ergodicity. A key generation algorithm, which is a randomized algorithm that outputs a public-key and a secret-key. The literature provides evidence that many types of chaotic cryptosystems have been proposed. Then, we need to define the following algorithms.

Cryptographic algorithms have played an important role in information security for protecting privacy.
