Sep 17, 2011 · Choosing between symmetric and asymmetric encryption depends on the use case. Symmetric encryption is used when a * small group of users need access to the information.

Jun 13, 2016 · The best answer is that it does both. TLS uses asymmetric encryption to first establish the identity of one or both parties. Secondly, it uses asymmetric encryption to exchange a key to a …

Apr 4, 2010 · Symmetric encryption algorithms typically are block ciphers. For any given algorithm, the block size is fixed. Then you pick from several different methods of making subsequent blocks …

Nov 4, 2016 · I am after a symmetric encryption/decryption routine in C#. I know there have been a few questions on this topic before, but most of the answers seem to be about the philosophy of …

Apr 17, 2013 · You should use the EVP_* functions to encrypt and decrypt. See EVP Symmetric Encryption and Decryption on the OpenSSL wiki. In fact, you should probably be using authenticated …

May 8, 2014 · Asymmetric encryption allows making the encryption key public, without revealing the decryption key; this is the obvious advantage of asymmetric encryption over symmetric encryption, …

Oct 25, 2019 · Re: the IV's visibility, the IV isn't secret but it still is critical to the encryption's security that it be generated correctly. If you ever reuse a key and an IV, or (in some situations) if the attacker can …

21 Symmetric encryption does not provides integrity. The amount of control that an attacker can have on encrypted data depends on the encryption type; and some specific details of some encryption modes …

Apr 25, 2012 · 34 Symmetric Key Cryptography : Symmetric key uses the same key for encryption and decryption. The main challenge with this type of cryptography is the exchange of the secret key …

May 1, 2012 · Asymmetric encryption usually uses complex mathematical operations, such as power and modulus, on very large numbers (2048 bits). These operations take time. Symmetric encryption …
