What is a symmetric encryption?
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.
Which algorithm do you use to exchange shared private keys?
The diffie hellman key exchange uses prime numbers to generate an asymmetric key pair which is used to create a secure channel over which a privet symmetric key can be sent.
How is cryptography used?
Cryptography is basically the process of hiding information in order to protect the sensitive information, data or message from unknown attacks for any reasons. Cryptography actually consists of two terms encryption and decryption. The process in which message is ciphered or encrypted is known as encryption and the process in which message is deciphered at recipients end is known as decryption. And this whole process is known as cryptography. Public keys and private keys are used in the process of cryptography. Cryptography can be seen as symmetric and asymmetric. In symmetric cryptography same key is used for both encryption and decryption while in asymmetric different keys are used for both encryption and decryption. Today Cryptography is used in various fields like ATM, e-banking, IT security, Maths etc.
What is the single name for group of keys?
The collective nouns are a bunch of keys or a ring of keys.
How does the circle of 5ths relate to the order of sharps and flats?
The Circle of Keys is a diagram of all Major and minor keys signatures. The sharp keys are arranged from the top, moving clockwise. The flat keys are arranged from the top, moving counterclockwise. There are fifteen Major keys: seven sharp keys, seven flat keys, and one key with no sharps or flats. Likewise, there are fifteen relative minor keys. The keys at the bottom of the circle are called enharmonic keys because their tones sound the same but are named and written differently. The Circle of Keys is sometimes called the Circle of Fifths because the keys are arranged an interval of a fifth apart.
