1、私钥加密,公钥解密:
//私钥加密,公钥解密--加密 PKCS8EncodedKeySpec pkcs8EncodedKeySpec = new PKCS8EncodedKeySpec(rsaprivateKey.getEncoded()); KeyFactory privateKeyFactory = KeyFactory.getInstance("RSA"); PrivateKey privateKey = privateKeyFactory.generatePrivate(pkcs8EncodedKeySpec); Cipher privateCipher = Cipher.getInstance("RSA"); privateCipher.init(Cipher.ENCRYPT_MODE, privateKey); byte[] result = privateCipher.doFinal(src.getBytes()); System.out.println("私钥加密,公钥解密--加密:"+Base64.encodeBase64String(result)); //私钥加密,公钥解密--解密 X509EncodedKeySpec x509EncodedKeySpec = new X509EncodedKeySpec(rsapublicKey.getEncoded()); KeyFactory publicKeyFactory = KeyFactory.getInstance("RSA"); PublicKey publicKey = publicKeyFactory.generatePublic(x509EncodedKeySpec); Cipher publicCipher = Cipher.getInstance("RSA"); publicCipher.init(Cipher.DECRYPT_MODE, publicKey); result = publicCipher.doFinal(result); System.out.println("私钥加密,公钥解密--解密:"+new String(result));
2、公钥加密,私钥解密:
//公钥加密,私钥解密---加密 x509EncodedKeySpec = new X509EncodedKeySpec(rsapublicKey.getEncoded()); publicKeyFactory = KeyFactory.getInstance("RSA"); publicKey = publicKeyFactory.generatePublic(x509EncodedKeySpec); publicCipher = Cipher.getInstance("RSA"); publicCipher.init(Cipher.ENCRYPT_MODE, publicKey); result = publicCipher.doFinal(src.getBytes()); System.out.println("公钥加密,私钥解密---加密:"+Base64.encodeBase64String(result)); //公钥加密,私钥解密---解密 pkcs8EncodedKeySpec = new PKCS8EncodedKeySpec(rsaprivateKey.getEncoded()); privateKeyFactory = KeyFactory.getInstance("RSA"); privateKey = privateKeyFactory.generatePrivate(pkcs8EncodedKeySpec); privateCipher = Cipher.getInstance("RSA"); privateCipher.init(Cipher.DECRYPT_MODE, privateKey); result = privateCipher.doFinal(result); System.out.println("公钥加密,私钥解密---解密:"+new String(result));
