How Does Public Key Encryption Work? | Public Key

Encryption algorithms - IBM After the symmetric encryption algorithm (such as AES) and a single encryption key are chosen, all data exchanges use this algorithm and key instead of the PKI method of encryption. In an SSL-encrypted session, all data is encrypted with the symmetric encryption algorithm immediately before … What is encryption and how does it protect your data? | Norton Twofish is considered one of the fastest encryption algorithms and is free for anyone to use. It’s used in hardware and software. Using encryption via SSL Most legitimate websites use what is called “secure sockets layer” (SSL), which is a form of encrypting data when it is being sent to and from a website. What is SSL? - SSL.com SSL/TLS works by binding the identities of entities such as websites and companies to cryptographic key pairs via digital documents known as X.509 certificates.Each key pair consists of a private key and a public key.The private key is kept secure, and the public key can be widely distributed via a certificate.

Secure Socket Layer Encryption (SSL Encryption) is a process undergone by data under the SSL protocol in order to protect that data during transfer and transmission by creating a channel, uniquely encrypted, so that the client and the server have a private communication link channel over the public Internet. This is how encryption protects SSL is used while establishing a secured connection between a server and client by allowing mutual authentication, integrity. Typically in real scenario it can be your browser and a website (a web server) or a mail client and a mail server. A unique encryption key (just a long string of random text) An encryption algorithm (a math function that “garbles” the data) You plug the data and the key into the algorithm and what comes out the other side is cipher text. That is, the encrypted form of your data which looks like gibberish. What Is AES 256-Bit Encryption? AES was developed in response to the needs of the U.S. government. In 1977, federal agencies relied on the Data Encryption Standard (DES) as their encryption algorithm. DES was created by IBM with a 56-bit symmetric-key block cipher design and was used successfully for close to 20 years.

However, cryptographic protocols like SSL, SSH and others, use different algorithms like SHA and RSA for different purposes. SSL uses RSA (encryption) or DH (with RSA, DSA or ECDSA signature) for key negotiation and AES or 3DES for data encryption. In the PGP protocol/file format, RSA, DSA and ElGamal are used for signing and encrypting.

In either case, the level of protection depends on the correctness of the implementation of the software and the cryptographic algorithms in use. SSL/TLS does not prevent the indexing of the site by a web crawler, and in some cases the URI of the encrypted resource can be inferred by knowing only the intercepted request/response size.
