Enum CryptoMode

    • Enum Constant Detail

      • EncryptionOnly

        public static final CryptoMode EncryptionOnly
        Encryption-only mode using AES/CBC.
      • AuthenticatedEncryption

        public static final CryptoMode AuthenticatedEncryption
        Authenticated encryption mode using AES/GCM, AESWrap, etc. Please note the limitation on the maximum message size in bytes that can be encrypted under this mode is 2^36-32, or ~64G, due to the security limitation of AES/GCM as recommended by NIST.
      • StrictAuthenticatedEncryption

        public static final CryptoMode StrictAuthenticatedEncryption
        Strictly enforce the use of authenticated encryption via AES/GCM, AESWrap, etc., and will throw security exception if an S3 object retrieved is found to be not protected using authenticated encryption. This means range-get operation is not supported in this mode, since range-get is not authenticated.

        Please note the limitation on the maximum message size in bytes that can be encrypted under this mode is 2^36-32, or ~64G, due to the security limitation of AES/GCM as recommended by NIST.

    • Method Detail

      • values

        public static CryptoMode[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (CryptoMode c : CryptoMode.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static CryptoMode valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
