示例 1：在 KMS 中创建客户托管的 KM AWS S 密钥

以下 create-key 示例创建对称加密 KMS 密钥。

要创建基本 KMS 密钥（对称加密密钥），您无需指定任何参数。这些参数的默认值会创建对称加密密钥。

由于此命令未指定密钥策略，因此，KMS 密钥将获得以编程方式创建的 KMS 密钥的默认密钥策略。要查看密钥策略，请使用 get-key-policy 命令。要更改密钥策略，请使用 put-key-policy 命令。

aws kms create-key

create-key 命令会返回密钥元数据，包括新 KMS 密钥的密钥 ID 和 ARN。在其他 KMS 操作中，您可以使用这些值来识别 AWS KMS 密钥。输出不包括标签。要查看 KMS 密钥的标签，请使用 list-resource-tags command。

输出：

{
    "KeyMetadata": {
        "AWSAccountId": "111122223333",
        "Arn": "arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab",
        "CreationDate": "2017-07-05T14:04:55-07:00",
        "CustomerMasterKeySpec": "SYMMETRIC_DEFAULT",
        "Description": "",
        "Enabled": true,
        "KeyId": "1234abcd-12ab-34cd-56ef-1234567890ab",

        "EncryptionAlgorithms": [
            "SYMMETRIC_DEFAULT"
        ]
    }
}

注意：create-key 命令不允许您指定别名。要为新 KMS 密钥创建别名，请使用 create-alias 命令。

示例 2：创建用于加密和解密的非对称 RSA KMS 密钥

以下 create-key 示例创建了一个 KMS 密钥，其中包含用于加密和解密的非对称 RSA 密钥对。

aws kms create-key \

示例 3：创建用于签名和验证的非对称椭圆曲线 KMS 密钥

创建用于签名和验证的非对称 KMS 密钥，其中包含非对称椭圆曲线（ECC）密钥对。尽管 SIGN_VERIFY 是 ECC KMS 密钥的唯一有效值，但 --key-usage 参数也是必需的。

aws kms create-key \
    --key-spec ECC_NIST_P521 \
    --key-usage SIGN_VERIFY

输出：

{
    "KeyMetadata": {
        "Arn": "arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab",

        "Enabled": true,
        "KeyId": "1234abcd-12ab-34cd-56ef-1234567890ab",
        "KeyManager": "CUSTOMER",

        "KeyUsage": "SIGN_VERIFY",
        "MultiRegion": false,
        "Origin": "AWS_KMS",
        "SigningAlgorithms": [

        ]
    }
}

示例 4：创建 HMAC KMS 密钥

以下 create-key 示例将创建 384 位 HMAC KMS 密钥。尽管 --key-usage 参数的 GENERATE_VERIFY_MAC 值是 HMAC KMS 密钥的唯一有效值，但该值也是必需的。

aws kms create-key \
    --key-spec HMAC_384 \
    --key-usage GENERATE_VERIFY_MAC

输出：

{
    "KeyMetadata": {
        "Arn": "arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab",
        "AWSAccountId": "111122223333",
        "CreationDate": "2022-04-05T14:04:55-07:00",

        "Origin": "AWS_KMS"
    }
}

示例 4：创建多区域主 KMS 密钥

以下 create-key 示例创建多区域主对称加密密钥。由于所有参数的默认值都会创建对称加密密钥，因此，此 KMS 密钥只需要 --multi-region 参数。在 AWS CLI 中，要指示布尔参数为真，只需指定参数名称即可。

aws kms create-key \
    --multi-region

输出：

{
    "KeyMetadata": {
        "Arn": "arn:aws:kms:us-west-2:111122223333:key/mrk-1234abcd12ab34cd56ef12345678990ab",

aws kms create-key \
    --origin AWS_CLOUDHSM \
    --custom-key-store-id cks-1234567890abcdef0

输出：

{
    "KeyMetadata": {
