Just use the javax.cryptoand java.securitypackages. It's in the Java standard platform.
只需使用javax.crypto和java.security包。它位于 Java 标准平台中。
KeyPair keys = KeyPairGenerator.getInstance("RSA").generateKeyPair();
Cipher cipher = Cipher.getInstance("RSA");
cipher.init(Cipher.ENCRYPT_MODE, keys.getPublic());
byte[] encrypted = cipher.doFinal(rawData);
