Steganography vs. Cryptography: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on February 7, 2024
Steganography is the art of hiding information within other non-secret media, while cryptography involves encrypting information into an unreadable format.

Key Differences

Steganography and cryptography both deal with securing information, but in different ways. Steganography involves concealing the existence of information within another harmless medium, making the hidden information imperceptible. Cryptography, on the other hand, focuses on transforming information into a secret code, altering its appearance but not hiding its existence.

In steganography, the main goal is to prevent the detection of hidden information. For example, embedding a secret message in a digital image or audio file. Cryptography aims to secure information by making it unintelligible to unauthorized readers, such as using encryption algorithms to scramble text.

Steganography does not alter the structure of the message but hides it within another file or medium. Cryptography transforms the message's structure and appearance into a coded format, requiring a key for decryption.

Steganography’s effectiveness lies in its ability to conceal the presence of communication. On the contrary, cryptography announces the presence of encrypted data, but ensures that only intended recipients can understand its contents.

The use of steganography can be traced back to ancient times, like writing on a messenger's shaved head and letting the hair grow back to hide the message. Cryptography also has a long history, with examples like the Caesar cipher used in Roman times to encrypt military communications.
