Hello Everyone,
Cryptography has been around since the beginning of civilization. Caesars cipher was one of the earliest methods of cryptography which shifted plain text three characters forward for encryption and three characters backwards for decryption. This was considered strong in its prime but, today, would be considered insecure. Cryptography has advanced over the years with the use of public keys, private keys and hashing. It is faster, complex and more secure.
Cryptographic attacks evolve as do the methods of security professionals. A common type of attack is a brute-force attack which can be halted by the use of a long key that is complex in nature. Attacks, today, are mainly online. Attackers have many resources and tools at their disposal. Access to such resources and tools, continuously serves as a threat to cryptography. Attacks are becoming more advanced so a strong system is crucial.
As technology, data and threats advance over the years, so do the methods of cryptography. Cryptography will become faster, complex and more secure. Take a look at past encryption methods such as Caesars Cipher and compare it to the methods we use today like symmetric encryption. Cryptography will constantly advance to reach the goal of PAIN (privacy, authentication, integrity, non-repudiation). The methods we use will change but the main concept and goal remain constant: Keep private data, private.
Best Regards,
Devin Powell
