Providing Decryption
|
Detailed explanation-1: -A symmetric key is used during both the encryption and decryption processes. To decrypt a particular piece of ciphertext, the key that was used to encrypt the data must be used. The goal of every encryption algorithm is to make it as difficult as possible to decrypt the generated ciphertext without using the key.
Detailed explanation-2: -Definition: The conversion of encrypted data into its original form is called Decryption. It is generally a reverse process of encryption. It decodes the encrypted information so that an authorized user can only decrypt the data because decryption requires a secret key or password.
Detailed explanation-3: -Both users have to agree on a secret key to communicate using symmetric cryptography. After that, each message is encrypted with that key it is transmitted and decrypted with the same key. Here, key distribution must be secret.
Detailed explanation-4: -At AWS, security is the top priority. Starting today, Amazon Simple Storage Service (Amazon S3) encrypts all new objects by default. Now, S3 automatically applies server-side encryption (SSE-S3) for each new object, unless you specify a different encryption option.
