What is encryption algorithm

Once encrypted, the message becomes a jumbled mess of random characters. But, equipped with the key I send you, you can decrypt it and find the original message. The technology comes in many forms, with key size and strength generally being the most significant differences in one variety to the next. At one time, Triple DES was the recommended standard and the most widely used symmetric algorithm in the industry. Triple DES uses three individual keys with 56 bits each.

The total key length adds up to bits, but experts would argue that bits in key strength is more accurate. Government and numerous organizations. Although it is highly efficient in bit form, AES also uses keys of and bits for heavy-duty encryption purposes. AES is largely considered impervious to all attacks, except for brute force, which attempts to decipher messages using all possible combinations in the , , or bit cipher. RSA is a public-key encryption algorithm and the standard for encrypting data sent over the internet.

The result of RSA encryption is a huge batch of mumbo jumbo that takes attackers a lot of time and processing power to break. Blowfish is yet another algorithm designed to replace DES. This symmetric cipher splits messages into blocks of 64 bits and encrypts them individually.

Blowfish is known for its tremendous speed and overall effectiveness. Meanwhile, vendors have taken full advantage of its free availability in the public domain. Computer security expert Bruce Schneier is the mastermind behind Blowfish and its successor Twofish. Keys used in this algorithm may be up to bits in length, and as a symmetric technique, you only need one key. With such a rise in application also comes security threats to how we communicate and exchange data.

This is a bigger problem at the level of businesses and organizations that have to employ the best safety measures to secure their data.

Data encryption algorithms are an effective security measure to protect information. Data that is encrypted is called ciphertext, while unencrypted data is called plaintext.

There are two types of encryption in use, the first is called asymmetric encryption or public-key encryption, and the second type is called symmetric encryption. The symmetric-key ciphers use only one key for both encrypting and decrypting information sticking to the classic sense of how basic encryption works. Although the symmetric-key encryptions are faster than the asymmetric encryption, the receiver cannot decrypt the data until the sender shares the encryption key. This means companies will have to find a way to manage and distribute a large number of keys securely.

Therefore many have migrated to adapting the asymmetric algorithms to encrypt their data for ease of use. The asymmetric encryption, on the other hand, is much more convenient and are also referred to as public-key encryption. Fundamentally the encryption and decryption algorithm will use two different keys where one is public, and the other is private. The public key gets shared with everyone while the private key is protected. The RSA algorithm is one example of popular public-key encryption used to secure information sent over insecure networks like the internet.

Both the public and the private key of the RSA algorithms can encrypt data to ensure its authenticity, confidentiality and integrity. This symmetric-key method of data encryption was made obsolete by the hackers who constantly exploited its vulnerabilities. Triple DES succeeded that and soon became the most widely used symmetric algorithm in the industry.

The algorithm uses a bit individual key with the total key length adding up to bits. However, since it is consecutive encryption, there is a middle-level vulnerability that decreases its protection to the level of a bit key. Before that, all encryption schemes were symmetric-key also called private-key. In symmetric-key schemes, the encryption and decryption keys are the same. Communicating parties must have the same key in order to achieve secure communication.

At one time, Triple DES was the recommended standard and the most widely used symmetric algorithm in the industry.

Triple DES uses three individual keys with 56 bits each. The total key length adds up to bits, but experts say that bits in key strength is more like it.

Though it is slowly being phased out, Triple DES is still a dependable hardware encryption solution for financial services and other industries. RSA is a public-key encryption algorithm and the standard for encrypting data sent over the internet.

The public key is used to encrypt a message and a private key to decrypt it. It takes attackers quite a bit of time and processing power to break this encryption code. Although it is extremely efficient in bit form, AES encryption also uses keys of and bits for heavy-duty encryption. AES is considered resistant to all attacks, with the exception of brute-force attacks, which attempt to decipher messages using all possible combinations in the , or bit cipher.

Still, security experts believe that AES will eventually become the standard for encrypting data in the private sector.
