What does a cryptographer do?

In today's computer-centric world, cryptography is most often associated with scrambling plaintext (ordinary text, sometimes referred to as cleartext) into ciphertext (a process called encryption ), then back again (known as decryption). Individuals who practice this field are known as cryptographers.

What is cryptography in Computer Science?

In computer science, cryptography refers to secure information and communication techniques derived from mathematical concepts and a set of rule-based calculations called algorithms, to transform messages in ways that are hard to decipher.

What are the different types of cryptography?

There are numerous cryptographic algorithms in use, but in general they can be broken into three categories: symmetric cryptography, asymmetric cryptography, and hash functions. Each has its own role to play within the cryptographic landscape. Symmetric cryptography. The Caesar cipher we discussed above is a great example of symmetric cryptography.
