Kotlin- RSA, AES, 3DES Encryption and Decryption with example
Quick Overview - RSA The RSA algorithm (Rivest-Shamir-Adleman) is a cryptographic algorithm that is used for specific security services or purposes, which enables public-key encryption and is widely used to secure sensitive data, particularly when it is being sent over an insecure network such as the HTTP. A public key is shared publicly, while a private key is secret and must not be shared with anyone. The following illustration highlights how asymmetric cryptography works: Example 1 : RSA Encryption and Decryption The Cipher Type: RSA/ECB/PKCS1Padding import java.security.spec.PKCS8EncodedKeySpec import javax.crypto.Cipher import java.security.spec.X509EncodedKeySpec import java.io.IOException import java.security.* import java.util.* class RSADemo { var privateKey: PrivateKey var publicKey: PublicKey companion object { // convert String publickey to Key object @Throws (GeneralSecurityException:: class , IOException:: class ) f...
