The cryptography uses different method by encrypting data at sender side and decrypted at receiver side .For securing the data there are two main types of cryptography algorithm, one is called symmetric and other is called asymmetric algorithms. In this paper I discuss about some asymmetric key algorithms with its advantages and disadvantages. In particular RSA, DSA, Diffie-Hellman,Elgamal, Elliptic curve cryptography and XTR for asymmetric encryption algorithms.Asymmetric key algorithms use different keys for encryption and decryption. The keys arePrivate Key and Public Key. . Public key for encrypt (conversion form data or information to code) and private key for decrypt (reciprocal of encryption or reverse process of encryption) a message.Public key is very efficient for authentication as well as for encryption. The decryption key cannot be derived from the encryption key. Asymmetric key algorithms used for transmitting encryption keys or other data securely even when the parties have no opportunity to agree on a secret key in private.
