... tures on it (i.e.) encrypt the confidential data's of the industry using best encryption algorithm. For that best cryptographic algorithm is discovered and then use it over the CRM application. Cryptographic Techniques are evaluated on some points. These points are avalanche effect due to one bit variation in plaintext keeping the key constant, avalanche effect due to one bit variation in key keeping the plaintext constant, memory required for implementation and simulation time required for encryption. The secured CRM system builds a great help in the relationship between employees and companies and provide secured access of system and allow secured transactions.
