Enum Class AesSpec.Mode

java.lang.Object

java.lang.Enum<AesSpec.Mode>

zeroecho.core.alg.aes.AesSpec.Mode

All Implemented Interfaces:

Serializable, Comparable<AesSpec.Mode>, Constable

Enclosing class:

AesSpec

public static enum AesSpec.Mode
extends Enum<AesSpec.Mode>

AES block modes supported by this implementation.

Mode selection determines IV length and security properties. GCM is an AEAD mode; CBC and CTR provide confidentiality only and must be combined with a MAC (Encrypt‑then‑MAC) when integrity/authenticity are required.

Since:

1.0

Enum Constant Details

CBC

public static final AesSpec.Mode CBC

Cipher Block Chaining (CBC).

Requires a 16‑byte IV. Supports AesSpec.Padding.PKCS5PADDING and AesSpec.Padding.NOPADDING. Not an AEAD mode; pair with a MAC for integrity.

GCM

public static final AesSpec.Mode GCM

Galois/Counter Mode (GCM), an authenticated encryption mode (AEAD).

Requires a 12‑byte IV and AesSpec.Padding.NOPADDING. The tag length must be 96–128 bits (multiple of 8). Supports Additional Authenticated Data (AAD). Recommended default.

CTR

public static final AesSpec.Mode CTR

Counter mode (CTR).

Uses a 16‑byte nonce/IV and AesSpec.Padding.NOPADDING. Not an AEAD mode; pair with a MAC for integrity.

Method Details

values

public static AesSpec.Mode[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static AesSpec.Mode valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
