Historia trougout, covet communication has played a vital role in espionage, diplomacy, and military operations. Two key techniques used to hide messages are steganography and cryptography. While both aim to protect information, they y don so in fundamentally different ways.

Co to jest Steganografia?

Steganography involves hiding a message with in another file or object, making the presence of thee message undistantable. Common methods include embedding text with images, audio files, or even videos. The goal is to conceal thee very y existence of thee e communicaton.

For example, a secret message could be hidden in thee least signitant bits of an image 's pixels. To an observer, the image appears normal, but a specific algorithm can extract thee hidden message.

Co to jest Kryptografia?

Kryptografy focuses on szyfrowane messages so that only authorized parties can read them. It transformations prefultext into ciphertext using algorytmy ms ande keys. Even if someone busteps thee message, they can not understand it without thee decryption key.

Popular cryptographic methods included de symetric critiption, like AES, and asymetric critiption, like RSA. These techniques are essential for security online communication, banking, and goverment secrets.
