Authentication The cryptographic techniques such as MAC and digital signatures can protect information against spoofing and forgeries. The secret key in cryptographyis also an input for encryption algorithm as this is the initial intelligible message or data that is fed into the algorithm as input. The algorithm relies on the key to exact substitution and transformation. Inspite of DSA being slower than RSA as the key size of the DSA is more which in turn makes encryption stronger. Private-key encryption (also called symmetric encryption or secret-key encryption) involves using the same key for encryption and decryption. It takes the ciphertext and the secret key, and it generates the original plain text. It is applied three times on the same data so it is such wastage of time. o Symmetric key is sent out-of-band distribution, an asymmetric method is used to send the key. Depending on the particular key used the algorithm outputs a different result. Advantage: Extremely Secure.
