Keypair diagram Generate an RSA Keypair in Node. As their names indicate, the private key should be kept secret, while the public key can be shared freely. The solution is to use an algorithm like RSA that generates a keypair containing a public and private key. This is problematic in the real world because it’s not practical or secure to share across a network. Using a shared key works for encryption works, but the problem is that both parties must agree upon the key. Hash function diagram Create a Hash in Node.jsĬreate a hash using the crypto module, then use it to compare two values.Ĭonst ` ) 5. Small probability of collision (unique).In this case, it’s easy for anyone to encrypt a piece of data, but only possible for someone with the correct key to decrypt it. ![]() It is an asymmetric encryption algorithm, which is just another way to say one-way.
