Generate Data Key From Kms

Generate a new (data) encryption key (eg with kmsgeneratedatakey) and store it only in memory for the next 2 steps; use this new encryption key to encrypt the data locally (eg using the sodium package or the AES function from the digest package). For more details on PCI DSS compliant services in AWS, you can read the PCI DSS FAQs. Q: How does AWS KMS secure the data keys I export and use in my application? You can request that AWS KMS generate data keys and return them for use in your own application. The data keys are encrypted under a master key you define in AWS KMS so that you can. »Argument Reference The following arguments are supported: description - (Optional) The description of the key as viewed in AWS console.; keyusage - (Optional) Specifies the intended use of the key. Valid values: ENCRYPTDECRYPT or SIGNVERIFY.Defaults to ENCRYPTDECRYPT.; customermasterkeyspec - (Optional) Specifies whether the key contains a symmetric key or an asymmetric key. Generates a unique data key. This operation returns a plaintext copy of the data key and a copy that is encrypted under a customer master key (CMK) that you specify. You can use the plaintext key to encrypt your data outside of KMS and store the encrypted data key with the encrypted data. Jan 20, 2020  I was recently doing some proof-of-concept work that required performing encryption using keys generated from AWS Key Management Service (KMS). I could find plenty of examples using symmetric encryption, but couldn’t find an end-to-end guide that showed how to generate keys from AWS and then use them to encrypt and decrypt data.

KMS caches encryption keys for a short period of time to avoid excessive hits to the underlying KeyProvider. This Cache is enabled by default (can be disabled by setting the hadoop.kms.cache.enable boolean property to false). This cache is used with the following 3 methods only, getCurrentKey and getKeyVersion and getMetadata. For the getCurrentKey method, cached.

  • ATTRIBUTES

Paws::KMS::GenerateDataKey - Arguments for method GenerateDataKey on Paws::KMS

This class represents the parameters used for calling the method GenerateDataKey on the AWS Key Management Service service. Use the attributes of this class as arguments to method GenerateDataKey.

Free keys rocket league generator. You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to GenerateDataKey.

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/kms/GenerateDataKey

EncryptionContext => Paws::KMS::EncryptionContextType

Specifies the encryption context that will be used when encrypting the data key.

An encryption context is a collection of non-secret key-value pairs that represents additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is optional when encrypting with a symmetric CMK, but it is highly recommended.

For more information, see Encryption Context (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#encrypt_context) in the AWS Key Management Service Developer Guide.

GrantTokens => ArrayRef[Str Undef]

A list of grant tokens.

For more information, see Grant Tokens (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#grant_token) in the AWS Key Management Service Developer Guide.

REQUIRED KeyId => Str

Identifies the symmetric CMK that encrypts the data key.

To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. When using an alias name, prefix it with 'alias/'. To specify a CMK in a different AWS account, you must use the key ARN or alias ARN.

For example:

  • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

  • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

  • Alias name: alias/ExampleAlias

  • Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias

To get the key ID and key ARN for a CMK, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

KeySpec => Str

Specifies the length of the data key. Use AES_128 to generate a 128-bit symmetric key, or AES_256 to generate a 256-bit symmetric key.

You must specify either the KeySpec or the NumberOfBytes parameter (but not both) in every GenerateDataKey request.

Valid values are: 'AES_256', 'AES_128'

Generate Data Key From Kms To Meters

NumberOfBytes => Int

Specifies the length of the data key in bytes. For example, use the value 64 to generate a 512-bit data key (64 bytes is 512 bits). For 128-bit (16-byte) and 256-bit (32-byte) data keys, use the KeySpec parameter.

You must specify either the KeySpec or the NumberOfBytes parameter (but not both) in every GenerateDataKey request.
