• API key 2FA can be added to an already existing API key via the Security tab of account management and can use either a static password or Google Authenticator. Note that adding 2FA to an API key also requires that the API client supports 2FA (provides the 2FA data for each call to.
• The Generate Key filter enables you to generate an asymmetric key pair, or a symmetric key. The generated keys are placed in message attributes, which are then available to be consumed by other filters.
• Jul 29, 2019 This process creates two keys. One is a public key, which you can hand out to anyone – in this case, you’ll save it to the server. The other one is a private key, which you will need to keep secure. The secure private key ensures that you are the only person who can encrypt the data that is decrypted by the public key.

Key Vault supports the following operations on key objects: Create: Allows a client to create a key in Key Vault. The value of the key is generated by Key Vault and stored, and isn't released to the client. Asymmetric keys may be created in Key Vault.

Nov 21, 2017  My today question is about data modelling. In many to many relationships, it is a must to create a key to connect 2 tables. Today i come accross the concept of composite primary which is a key made up from many collumn. However, i'm struggle to understand in which case i need create this composite primary key? This article explains how to generate CSR/Private Key pair using the command line interface on a Linux operating system. You will need an SSH client on your local computer if accessing via SSH, something like Putty (for windows) or the Terminal on a linux or mac computer. RandomKeygen is a free mobile-friendly tool that offers randomly generated keys and passwords you can use to secure any application, service or device. KEY RandomKeygen - The Secure Password & Keygen Generator.

Description¶

Generates a unique symmetric 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 AWS KMS and store the encrypted data key with the encrypted data.

To generate a data key, specify the symmetric CMK that will be used to encrypt the data key. You cannot use an asymmetric CMK to generate data keys. To get the type of your CMK, use the DescribeKey operation.

You must also specify the length of the data key. Use either the KeySpec or NumberOfBytes parameters (but not both). For 128-bit and 256-bit data keys, use the KeySpec parameter.

If the operation succeeds, the plaintext copy of the data key is in the Plaintext field of the response, and the encrypted copy of the data key in the CiphertextBlob field.

To get only an encrypted copy of the data key, use GenerateDataKeyWithoutPlaintext . To generate an asymmetric data key pair, use the GenerateDataKeyPair or GenerateDataKeyPairWithoutPlaintext operation. To get a cryptographically secure random byte string, use GenerateRandom .

You can use the optional encryption context to add additional security to the encryption operation. If you specify an EncryptionContext , you must specify the same encryption context (a case-sensitive exact match) when decrypting the encrypted data key. Otherwise, the request to decrypt fails with an InvalidCiphertextException. For more information, see Encryption Context in the AWS Key Management Service Developer Guide .

The CMK that you use for this operation must be in a compatible key state. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide .

We recommend that you use the following pattern to encrypt data locally in your application:

• Use the GenerateDataKey operation to get a data encryption key.
• Use the plaintext data key (returned in the Plaintext field of the response) to encrypt data locally, then erase the plaintext data key from memory.
• Store the encrypted data key (returned in the CiphertextBlob field of the response) alongside the locally encrypted data.

To decrypt data locally:

• Use the Decrypt operation to decrypt the encrypted data key. The operation returns a plaintext copy of the data key.
• Use the plaintext data key to decrypt data locally, then erase the plaintext data key from memory.

Synopsis¶

Options¶

--key-id (string)

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 .

--encryption-context (map)

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 in the AWS Key Management Service Developer Guide .

Git Generate Key

Shorthand Syntax:

JSON Syntax:

--number-of-bytes (integer)

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.

--key-spec (string)

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.

Possible values:

• AES_256
• AES_128

--grant-tokens (list)

/microsoft-office-standard-2010-key-generator.html. A list of grant tokens.

For more information, see Grant Tokens in the AWS Key Management Service Developer Guide .

Syntax:

--cli-input-json (string)Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string)Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Generate RSA keys with SSH by using PuTTYgen

One effective way of securing SSH access to your cloud server is to usea public-private key pair. This means that a public key is placed onthe server and a private key is placed on your local workstation.Using a key pair makes it impossible for someone to log in by using justa password, as long as you set up SSH to deny password-basedauthentication.

This article provides steps for generating RSA keys by using PuTTYgen onWindows for secure SSH authentication with OpenSSH.

Generate keys

Generate Key Data To Support Phone

In Windows, use PuTTYgen to generate your public and private keys.

1. If needed, download PuTTYgen from the PuTTY download page.(PuTTYgen might have been installed previously with PuTTY or WinSCP.)
2. Launch the program, and then click the Generate button.The program generates the keys for you.
3. Enter a unique key passphrase in the Key passphrase andConfirm passphrase fields.For additional information about using passphrases,see Log in with a SSH Private Key on Windows.
4. Save the public and private keys by clicking the Save public keyand Save private key buttons.
5. From the Public key for pasting into OpenSSH authorized_keys filefield at the top of the window, copy all the text (starting with ssh-rsa)to your clipboard by pressing Ctrl-C.You need this key available on your clipboard to paste eitherinto the public key tool in the Control Panel or directly into theauthorized keys on your cloud server.

Use the key pair

You can use the RSA key pair in the following ways.

Specify your SSH key when creating a new cloud server

When you create a cloud server, you can assign a public key from the list of keys.If your key is not already in the list, you may add it, and then assign it.

Add a new public key to the list

1. Under Advanced Options on the Create Server page, click Manage SSHKeys.
2. Select public key for the cloud server from the SSH Keys listand click Add Public Key.
3. Enter the key name, select the region, and paste the entire publickey into the Public Key field. Then click Add Public Key.
4. Go back to the Create Server page, and confirm that your key is listedin the SSH Key list.

Generate Key Pair

1. Under Advanced Options on the Create Server page, select the publickey you want to use from the SSH key drop-down menu.
2. When you are done specifying the all the other details for the server,click Create Server.

Assign your SSH Key to an existing cloud server

To make use of your newly generated RSA key pair, you must tell PuTTY touse it when connecting to your cloud server.

1. To edit the file (or create it), run the following command on the cloud server:

2. Paste the text onto its own line in the file.

   You must have the key available in your clipboard to paste it. The key and itsassociated text (the ssh-rsa identified at the start and the comment at the end)must be on one line in the file. If the text is word-wrapped onto multiple linesan error might occur when connecting.

3. If you created the authorized_keys file, change its permissionsafter you’re done editing it by running the following command:

4. Open PuTTY, and go to the SSH > Auth section.

5. Browse to the location of the key file, and load the private key.

6. Go to the Session page, and save the session. This saves the configurationso that PuTTY uses the key every time that you connect to your cloudserver.

After you save your session, your key is loaded automatically when youconnect to your server.
