What is DES in ecommerce?
DES stands for Data Encryption Services which uses encryptrion or decryption services in which the sender & reciever share a single common key to encrypt or decrypt the message.
What is an accurate description of an asymmetric encryption technology?
It is an encryption process that uses a public and private key pair to encrypt/decrypt data.
Does symmetric cryptography use the same key to encrypt and decrypt a message?
Yes
What is a characteristic of public key cryptography?
If data is encrypted with the public key, only the private key can decrypt itAnswer Explanation: Public key encryption uses an asymmetric algorithm, which uses a public key and private key combination for the encryption and decryption process. If data is encrypted with the public key, only the private key can decrypt the data. The public key cannot decrypt a message that was encrypted with the public key. Alternatively, if data is encrypted with the private key, only the public key can decrypt the data.
What is the meaning of encrypts?
The meaning of asymmetric encryption is that one key that is unique to a recipient is used only to decrypt data instead of a key being used to encrypt and decrypt that data.
What is triple encryption?
For some time it has been common practice to protect and tansport a key for DES encryption with triple-DES (3DES). The function follows an encrypt-decrypt-encrypt (EDE) sequence. Decrypt sequence is simply the same (encrypt) operation with the keys reversed.
What is secret key?
In secret key cryptography, a single key is used for both encryption and decryption. The sender uses the key (or some set of rules) to encrypt the plaintext and sends the cipher text to the receiver. The receiver applies the same key to decrypt the message and recover the plaintext. Because a single key is used for both functions, secret key cryptography is also called symmetric encryption.
What is secret key cryptography?

The receiver applies the same key to decrypt the message and recover the plaintext. Because a single key is used for both functions, secret key cryptography is also called symmetric encryption.
Which type of encryption technology uses two keys to encrypt and decrypt data?
If the keys are different, then it is asymmetrical. If it is the same key used twice to encode and decode; then it is symmetrical.
What is conventional encryption?
Conventional encryption ciphers rely on a single key for both encryption and decryption. Modern protocols will use a private key for encryption and a different public key for decryption. These two keys are mathematically related in a fashion that allows them to encrypt/decrypt the same data successfully.
How you can decrypt the file?
Only with the proper Encryption key, without that it's lost forever. Encryption uses a different algorithm every time, and only the key generated at the time of encryption can decrypt that file.
How many different keys will be required to give four people the ability to encrypt and decrypt the message using a symmetric cryptography algorithm?
ONEAnswer Explanation: Only one key would be required for everyone to be able to encrypt and decrypt the message. Symmetric cryptography uses the same "shared secret" key for encrypting and decrypting a message. A message encrypted using a symmetric encryption algorithm can be decrypted by anyone with the key. For this reason it is very important to ensure that the key is protected from unauthorized use. One of the primary security issues surrounding the use of symmetric cryptography is the method used to transport the key to users who need it, as most forms of communication are susceptible to eavesdropping.
