If someone wants to use the Base64 package now included in Java instead of the org. But as Joana and Jeroen said, the encryption should be done using the public key and the decryption with the private key. Can you suggest how can I generate public and private key like………. Writing code in comment? Users say Alice and Bob pick private values a and b and they generate a key and exchange it publicly, the opposite person received the key and from that generates a secret key after which they have the same secret key to encrypt. But how can I send public key to the server to decrypt the password. Joana Chavez La Valle.

    Step 2: Alice selects a secret no(a) and computes ga mod p, let’s call it A. Alice sends A to Bob.

    Step 6: If S_A=S_B then Alice and Bob can agree for future communication. class DiffieHellman { public static void main(String args[]) { Scanner sc nextInt (); // Substitution encryption StringBuffer substitutionOutput.

    I think you doing it the other wrong way around. Users say Alice and Bob pick private values a and b and they generate a key and exchange it publicly, the opposite person received the key and from that generates a secret key after which they have the same secret key to encrypt.

    For a better understanding of Elliptic Curve Cryptography, it is very important to understand the basics of Elliptic Curve. Elliptic curves could intersect atmost 3 points when a straight line is drawn intersecting the curve. Prashant Jeet Singh.

    In this example, we create a class that can load the Public and the Private keys from their files and then uses them to encrypt and decrypt a String and a File.

    Diffie-Hellman algorithm The Diffie-Hellman algorithm is being used to establish a shared secret that can be used for secret communications while exchanging data over a public network using the elliptic curve to generate points and get the secret key using the parameters.

    1. The data encrypted using one key can be decrypted with the other. Thanks for the example, though you encrypt with the public keyand decrypt with a private key.
