The Cryptography is a Greek word whichimplies the craft of ensuring data by changing it into amuddled organization and unreadable format.Cryptography is a method to secure sensitive data forstorage and communication in the presence of thirdparties called adversaries. It is a mix of arithmetic andsoftware engineering. The drastic growth of the Internetover a period of time made an unintentional security.Even though security is the measure worries over theinternet, numerous applications have been created andstructured without considering fundamental destinationsof data security that is confidentiality, authentication,and protection. To gain some undesirable clients orindividuals to gain admittance to the data, cryptographyis required. This paper introduces a new hybrid securitycipher by combining the two most important Cipherssuch as Polybius Cipher and Vigenere Cipher. Thishybrid encryption cipher provides greater security ascompared to classic ciphers.
