枚举 CryptoMode

java.lang.Object

java.lang.Enum<CryptoMode>

com.ksyun.ks3.service.encryption.model.CryptoMode

所有已实现的接口:

Serializable, Comparable<CryptoMode>

public enum CryptoMode
extends Enum<CryptoMode>

Denotes the different cryptographic modes available for securing an S3 object via client-side encryption. Crypto mode can be configured via CryptoConfiguration when the S3 encryption client is constructed.

枚举常量概要

枚举常量

枚举常量和说明
AuthenticatedEncryption Authenticated encryption mode using AES/GCM, AESWrap, etc.
EncryptionOnly Encryption-only mode using AES/CBC.
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.

枚举常量详细资料

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.

方法详细资料

values

public static CryptoMode[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (CryptoMode c : CryptoMode.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static CryptoMode valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
