# What are the applications of RSA Algorithm?

There are some application of RSA Algorithm are as follows −

• RSA algorithm is asymmetric cryptography algorithm as it operate on two different keys such as public key and private key. The public key is likely to everyone, and private key remains private. The public key includes two numbers, one of which is a multiplication of two large prime numbers.

• The RSA algorithm is based on the complexity included in the factorization of large numbers. The RSA algorithm depends on the fact that there is no effective method to factor very large numbers. Therefore, it can deducing an RSA key would take a large amount of time and processing power.

• In RSA encryption, a message is encrypted with a code is known as a public key, which does not required to be hidden. It is based on the mathematical features of the RSA algorithm, because a message has been encrypted with the public key, it can only be decrypted by another key, which is known as the private key. Therefore, a set of key, which are public and private keys, is needed to read such messages.

• The application of the RSA algorithm derives its security from factoring the huge integral component, which are the product of two large numbers. It is simply to multiple any of the figures.

The computation of the original primary numbers from the sum or variables is difficult because the time it takes even using supercomputers is the disadvantage of the RSA algorithm.

• The most ambiguous feature of RSA cryptography is the public and private key generation algorithm. They primarily test algorithm produced using the Rabin Miller test, which are p and q, the two large numbers.

A module, n, is calculated by multiplying p and q. This number can be used for a private and public key and supports the connection between them is known as the key length, and the length of the key is generally defined in bits.

• RSA encryption is generally used in combination with other encryption schemes, or for digital signatures which can validate the authenticity and integrity of a message. It cannot be used to encrypt entire messages or files, because it is less effective and more resource-heavy than symmetric-key encryption.

• In RSA public keys, two large, randomly produced prime factors contribute to their complexity. The numbers and sequences are generated randomly. RSA algorithm depends on using prime factorization as an approach of one-way encryption, so its complete security premise is based on its use.

• RSA was used with Transport Layer Security (TLS) to secure communications among two individuals. Other famous products and algorithms, such as the Pretty Good Privacy algorithm, and it can use RSA either currently or in the previous. Virtual Private Networks (VPNs), email services, web browsers, and multiple connection channels have used RSA as well.
