WebJan 12, 2024 · Cryptology is a young science. Though it has been used for thousands of years to hide secret messages, systematic study of cryptology as a science (and perhaps an art) just started around one hundred years ago.

WebNov 28, 2024 · Cryptography is the field that looks at how to keep information secure so that only the person who is supposed to see it can. Often the job involves cracking—or hacking—codes that encrypt data. Cryptographers use their knowledge of codes and computers to keep data and information safe. gainlord pty ltdWebCiphers are arguably the corner stone of cryptography.
