Cryptography is the technique of using mathematics and computation to convert plain text to unintelligible text so only those persons for whom the information is intended can access and read the data. Cryptography not only facilitates the storing and transferring of the data safely across the network but can also be used for authentication.
With cryptography, only concerned people or legitimate parties can access and decrypt the data, thus maintaining the confidentiality of the data being transmitted and received.
The foremost important reason to use cryptography is to maintain confidentiality, accuracy and integrity of data. Cryptography makes eavesdropping attacks impossible over the network and it ensures information and data security.
Cryptography also ensures data is safely stored, and even if it is accessed by a third person, they cannot read the data in plaintext.
Features of cryptography Confidentiality: cryptography assures that the information can be accessed by the intended persons and no other third person can access the information. Integrity: cryptography ensures that the information cannot be modified while it is in storage or transition between the intended sender and receiver. Non-repudiation: cryptography ensures that the owner or sender of the information cannot deny his or
