在C#中,SecretKeySpec類用于表示對(duì)稱算法的密鑰。密鑰管理方法主要包括以下幾種:
byte[] keyBytes = new byte[16]; // 128位密鑰
new Random().NextBytes(keyBytes);
SecretKeySpec keySpec = new SecretKeySpec(keyBytes, "AES");
byte[] keyBytes = { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F };
SecretKeySpec keySpec = new SecretKeySpec(keyBytes, "AES");
string base64Key = "somesecretkey";
byte[] keyBytes = Convert.FromBase64String(base64Key);
SecretKeySpec keySpec = new SecretKeySpec(keyBytes, "AES");
KeyStore keyStore = KeyStore.GetInstance("JKS");
keyStore.Load(new FileInputStream("keystore.jks"), "keystorepassword".ToCharArray());
SecretKeySpec keySpec = new SecretKeySpec(keyStore.GetKey("alias", "keypassword".ToCharArray()), "AES");
通過以上方法,可以有效地管理SecretKeySpec類中的密鑰。
