Difference between Symmetric And Asymmetric Encryption

Symmetric Encryption: It is the simplest kind of encryption that involves only one secret key to cipher and decipher information. It uses a secret key that can either be a number, a word or a string of random letters. It is blended with the plain text of a message to change the content in a particular way. The sender and the recipient should know the secret key that is used to encrypt and decrypt all the messages. While.

Asymmetrical encryption is also known as public key cryptography, which is a relatively new method, compared to symmetric encryption. Asymmetric encryption uses two keys to encrypt a plain text. Secret keys are exchanged over the Internet or a large network. It ensures that malicious persons do not misuse the keys. It is important to note that anyone with a secret key can decrypt the message and this is why asymmetrical encryption uses two related keys to boosting security. A public key is made freely available to anyone who might want to send you a message. The second private key is kept a secret so that you can only know.

Reason

Symmetric encryption is a type of encryption where only one key (a secret key) is used to both encrypt and decrypt electronic information. The entities communicating via symmetric encryption must exchange the key so that it can be used in the decryption process. This encryption method differs from asymmetric encryption where a pair of keys, one public and one private, is used to encrypt and decrypt messages.

By using symmetric encryption algorithms, data is converted to a form that cannot be understood by anyone who does not possess the secret key to decrypt it. Once the intended recipient who possesses the key has the message, the algorithm reverses its action so that the message is returned to its original and understandable form. The secret key that the sender and recipient both use could be a specific password/code or it can be random string of letters or numbers that have been generated by a secure random number generator (RNG).

Asymmetrical encryption is basically known as the Public Key Cryptography. This means that there are two keys to encrypt a plain text. Secret keys are exchanged over a connection to ensure that security is prioritized before messages are sent. This way, any malicious people cannot misuse the keys. Anyone with a secret key can decrypt the message which is why asymmetric uses two keys. A message encrypted using a public key can be decrypted using a public key. Security for the public key is usually not required because, like the name suggests, it is publicly available. Somewhat of a hidden in plain site strategy is used in Asymmetrical encryption. Popular types of Asymmetric algorithms include RSA, Eliptic curve techniques, DSA, and PKCS. When a server and a client require a secure encrypted communication, they send a query over the network to the other party, which sends back a copy of the certificate. The other party's public key can be extracted from the certificate. A certificate can also be used to uniquely identify the holder.

Unlike Asymmetrical, Symmetrical encryption involves only ONE secret key to cipher and decipher information. a secret key that can either be a number, a word or a string of random letters. It is a blended with the plain text of a message to change the content in a particular way. The most widely used symmetric algorithm is AES-128, AES-192, and AES-256.

Asymmetrical encryption usually has better security than symmetrical.
