Security issues are becoming a domain where a lot of researches and experimentations are happening today. A lot of algorithms assosciated with encryption,decryption etc have been introduced. RSA is one of those.
RSA is an algorithm for public-key cryptography that is based
on the presumed difficulty of factoring large integers.
A user of RSA creates and then publishes the product of two
large prime numbers, along with an auxiliary value, as their
public key. The prime factors must be kept secret.
Anyone can use the public key to encrypt a message, but only
someone with knowledge of the prime factors can feasibly
decode the message.
Brute force search is an exhaustive key search, which is a cryptanalytic attack that can, in
theory, be used against any encrypted data.
Checking all possible keys until the correct key is found.
Time taken to mount a successful brute-force and the resources required for a brute-force attack grow
exponentially with increasing key siz
