Cryptology tutorial
WebCryptography, a subset of cybersecurity, is the field of implementing and perfecting data encryption to protect sensitive information. It’s an interdisciplinary practice employed in areas as diverse as government, academia, tech, and finance. A straightforward cryptography definition is the art of writing and breaking codes. WebTraditional Ciphers. In the second chapter, we discussed the fundamentals of modern cryptography. We equated cryptography with a toolkit where various cryptographic techniques are considered as the basic tools. One of these tools is the Symmetric Key Encryption where the key used for encryption and decryption is the same.

WebCryptography Hash functions. Hash functions are extremely useful and appear in almost all information security applications. A hash function is a mathematical function that converts a numerical input value into another compressed numerical value. The input to the hash function is of arbitrary length but output is always of fixed length.
