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.
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 the term for a website that uses encryption techniques to protect its data?
secure site
What is hushmail?
See the related link for more information. Hushmail offers secure and unreadable email to its users. It uses PGP encryption and a key management system to secure email for the sender and receiver.
How does asymmetric encryption provide confidentiality?
Asymmetric encryption can provide confidentiality in two ways:1) messages encrypted using the public key of the recipient can only be decrypted using the private key of the recipient - which only the recipient should possess.2) It can be used as part of a negotiation process between two users to establish a temporary shared key through a process such as the following:User A sends a challenge message to user B which is encrypted with user B's public key to initiate secure communications.User B decrypts the message and sends the correct response back to user A encrypted with user A's public keyThe two users are now authenticated to each otherAt this point A can send a proposed symmetric key to B encrypted with B's private keyAll further communications are encrypted via the shared symmetric keyIn this second scenario, the asymmetric encryption only facilitates the establishment of confidentiality via the eventually shared symmetric key by securing the initial negotiations.
What kind of encryption uses the concept of public keys?
Asymmetric encryption employs the use of public/private key pairs.
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 asymmetric encryption involves keys?
Symmetric encryption requires one key known by both parties. Asymmetric encryption uses two keys, one encryption key known publicly and one decryption key known only by the recipient.Or more simply put,YesA public and private key
Which encryption process uses two keys and includes RSA as a common solution?
Type your answer here... AsymmetricAnswer Explanation: Asymmetric encryption uses a key pair, a public key, and a private key for the encryption and decryption process. One key is used to encrypt the information, and the other key is used to decrypt it. Asymmetric encryption uses Rivest Shamir Adleman (RSA) as a common asymmetric solution to encrypt information.It could be that the person posing the question was looking for SSL (or TLS) which use encryption to secure communications. While RSA is not the only encryption method accepted, both SSL and TLS can, and commonly DO, use RSA as the negotiated encryption scheme.
Who or what types of website or companies use symmetric key encryption?
If you are using an encrypted channel, then at some point everyone uses symmetric encryption. It is fast (compared to asymmetric).The first part of an encrypted conversation will probably use asymmetric encryption to provide the shared private key that is later on used for the bulk part of data conversations on an encrypted channel.
What is the most popular symmetric encryption system used over the Web?
The most common hybrid system is based on the Diffie-Hellman key exchange, which is a method for exchanging private keys using public key encryption. Diffie-Hellman key exchange uses asymmetric encryption to exchange session keys. These are limited-use symmetric keys for temporary communications; they allow two entities to conduct quick, efficient, secure communications based on symmetric encryption, which is more efficient than asymmetric encryption for sending messages. Diffie_Hellman provides the foundation for subsequent developments in public key encryption. It protects data from exposure to third parties, which is sometimes a problem when keys are exchanged out-of-land.
What is symmetric and asymmetric?
From another user: Symmetric cryptography uses the same secret (private) key to encrypt and decrypt its data whereas asymmetric uses both a public and private key. Symmetric requires that the secret key be known by the party encrypting the data and the party decrypting the data. Asymmetric allows for distribution of your public key to anyone with which they can encrypt the data they want to send securely and then it can only be decoded by the person having the private key. This eliminates the need of having to give someone the secret key (as with symmetric encryption) and risk having it compromised. The issue with asymmetric is that it is about 1000 times slower than symmetric encryption which makes it impractical when trying to encrypt large amounts of data. Also to get the same security strength as symmetric, asymmetric must use strong a stronger key than symmetric.
Difference between symmetric and asymmetric key cryptography?
Symmetric cryptography uses the same secret (private) key to encrypt and decrypt its data whereas asymmetric uses both a public and private key. Symmetric requires that the secret key be known by the party encrypting the data and the party decrypting the data. Asymmetric allows for distribution of your public key to anyone with which they can encrypt the data they want to send securely and then it can only be decoded by the person having the private key.

The issue with asymmetric is that it is about 1000 times slower than symmetric encryption which makes it impractical when trying to encrypt large amounts of data. Also to get the same security strength as symmetric, asymmetric must use strong a stronger key than symmetric. If you do a quick search on the differences between symmetric and asymmetric you can find many more explanations. This just a quick overview.
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.
Is the de facto standard developed by Netscape and used by all browsers it uses an encryption system that uses a digital certificate?
SSL
What are the difference between DES and RSA algorithm?
DES is a symmetric cryptographic algorithm, while RSA is an asymmetric (or public key) cryptographic algorithm. Encryption and decryption is done with a single key in DES, while you use separate keys (public and private keys) in RSA. DES uses 56-bit keys for encryption while RSA uses 2600-bits of KEY
Which type of encryption process uses the same key for encryption and decryption?
A: Symmetric
