What are the key milestones in the evolution of cryptographic algorithms?

The evolution of cryptographic algorithms includes several key milestones, such as the development of symmetric key algorithms like DES in the 1970s, the introduction of public key cryptography with RSA in 1977, and the emergence of modern algorithms like AES in 2001.

Can you explain how RSA works?

RSA works by generating two large prime numbers and multiplying them to create a modulus. The public key consists of this modulus and an exponent, while the private key is derived from the prime factors. It allows secure data transmission.

What are some common uses of cryptographic algorithms today?

Common uses include securing online transactions, encrypting emails, protecting sensitive data, and ensuring secure communications over the internet.

How do cryptographic algorithms ensure data integrity?

They use hash functions to create a unique fingerprint of data. Any change in the data results in a different hash, indicating tampering.

What future trends do you see in cryptography?

Future trends may include quantum-resistant algorithms, increased use of blockchain technology, and advancements in homomorphic encryption.
