10 Interesting Fact About Cryptography and encryption techniques

Transcript:

Languages:

• Cryptography comes from the Greek krypto which means hidden and graphein which means writing, so that cryptography can be interpreted as an art or science for hidden writing.
• Initially, cryptography is used for military and diplomatic purposes, but now cryptography is used in various fields such as finance, information technology, and telecommunications.
• One of the important figures in the history of cryptography is Julius Caesar, who created a simple encryption technique known as Caesar Password.
• There are several types of encryption techniques, such as substitution, transposition, and a combination of both.
• Modern cryptography uses symmetrical key algorithms and asymmetrical locks.
• Symmetrical lock algorithms use the same key for data encryption and decryption.
• Asymmetrical key algorithms use two different keys, namely public keys and private keys.
• Cryptography is also used in bitcoin and blockchain technology to secure user transactions and identity.
• One method of attack on encryption is Brute Force Attack, where the attacker tries all key combinations to get encrypted messages.
• Cryptography is also used in computer security, such as HTTPS protocols that are used to secure communication between browsers and web servers.
