What Cryptography in brief information.


Cryptography

Hi there 
How are you I think you are good and if you did not so read this post end to end and you will be happy  I am damn sure. 
so let's start this bro.


WHAT IS Cryptography?

 The "Cryptography" is the study and application of techniques that hind the real meaning of information by transforming it into no human-readable formate and "vice versa"
before plain text into ciphertext, this ciphertext is encrypted in a human unreadable format.





THIS is only for education purpose and please don't use for evil works.

 so now we know what is "cryptography" and how it's working so now time to know more about it.

 let's assume you have sent a message to a friend and you have written your message on plain text and if you want this very secret massage anyone can't read this massage so the best to do this just convert your massage into encrypt that and one can read your message.
Cryptography Types?

 1. MD5

 In cryptography, MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications and is also commonly used to check the integrity of files.

 2. SHA 
SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA". ...

SHA-1: A 160-bit hash function that resembles the earlier MD5 algorithm. ...

SHA-2: A family of two similar hash functions, with different block sizes, known as SHA-256 and SHA-512.

3.RC4

 The RC4 Encryption Algorithm, developed by Ronald Rivest of RSA, is a shared key stream cipher algorithm requiring a secure exchange of a shared key.
