This library contains the implementation of popular crypto algorithms from scratch using C++

Some classical/modern ciphers in C language and Python to encrypt and decrypt important information and keep the information safe, such as integrity, authentication, confidentiality and availability of the data. Some implemented ciphers are: Affine, DES and AES (with modes of operation for BMP images)

Measurement of encryption and decryption times using different operating modes for the AES Cipher

It is an Advanced Encryption Standard with 128-bit key values and also its some versions like Cipher Block Chaining and Output Feedback.

Program to encrypt and decrypt files using ECB, CBC, CFB, OFB.

High performance, Bi-directional gRPC file streaming encryption service using Four square cipher, One time pad, SHA1, XXTEA, Output-feedback block cipher.

Алгоритм шифрования SAFER+. Работает как с тектом, так и с bmp картинками. Присутствует режим работы ofb.

AES 128/192/256 encryption/decryption in modes: CBC, ECB, CTR, OFB & CFB

This project implements the International Data Encryption Algorithm (IDEA) in Output Feedback (OFB) mode, combined with Schnorr signature for data integrity and Elliptic Curve Diffie-Hellman (ECDH) for secure key exchange. It ensures robust encryption, authentication, and secure communication.

Feistel network implementation with EBC, CBC, OFB modes.
