aws-cloudhsm > help key generate-asymmetric-pair rsa
Generate an RSA key pair

Usage: key generate-asymmetric-pair rsa [OPTIONS] --public-label <PUBLIC_LABEL> --private-label <PRIVATE_LABEL> --modulus-size-bits <MODULUS_SIZE_BITS> --public-exponent <PUBLIC_EXPONENT>

Options:
      --cluster-id <CLUSTER_ID>
          Unique Id to choose which of the clusters in the config file to run the operation against. If not provided, will fall back to the value provided when interactive mode was started, or error
      --public-label <PUBLIC_LABEL>
          Label for the public key
      --private-label <PRIVATE_LABEL>
          Label for the private key
      --session
          Creates a session key pair that exists only in the current session. The key cannot be recovered after the session ends
      --modulus-size-bits <MODULUS_SIZE_BITS>
          Modulus size in bits used to generate the RSA key pair
      --public-exponent <PUBLIC_EXPONENT>
          Public exponent used to generate the RSA key pair
      --public-attributes [<PUBLIC_KEY_ATTRIBUTES>...]
          Space separated list of key attributes to set for the generated RSA public key in the form of KEY_ATTRIBUTE_NAME=KEY_ATTRIBUTE_VALUE
      --private-attributes [<PRIVATE_KEY_ATTRIBUTES>...]
          Space separated list of key attributes to set for the generated RSA private key in the form of KEY_ATTRIBUTE_NAME=KEY_ATTRIBUTE_VALUE
  -h, --help

Arguments

<CLUSTER_ID>

The ID of the cluster to run this operation on.

Required: If multiple clusters have been configured.

<MODULUS_SIZE_BITS>

Specifies the length of the modulus in bits. The minimum value is 2048.

Required: Yes

<PRIVATE_KEY_ATTRIBUTES>

Specifies a space separated list of key attributes to set for the generated RSA private key in the form of KEY_ATTRIBUTE_NAME=KEY_ATTRIBUTE_VALUE (for example, token=true)

For a list of supported key attributes, see Key attributes for CloudHSM CLI.

Required: No

<PRIVATE_LABEL>

Specifies a user defined label for the private-key. The maximum size allowable for label is 127 characters for Client SDK 5.11 and after. Client SDK 5.10 and before has a limit of 126 characters.

Required: Yes

<PUBLIC_EXPONENT>

Specifies the public exponent. The value must be an odd number greater than or equal to 65537.

Required: Yes

<PUBLIC_KEY_ATTRIBUTES>

Specifies a space separated list of key attributes to set for the generated RSA public key in the form of KEY_ATTRIBUTE_NAME=KEY_ATTRIBUTE_VALUE (for example, token=true)

For a list of supported key attributes, see Key attributes for CloudHSM CLI.

Required: No

<PUBLIC_LABEL>

Specifies a user defined label for the public-key. The maximum size allowable for label is 127 characters for Client SDK 5.11 and after. Client SDK 5.10 and before has a limit of 126 characters.

Required: Yes

<SESSION>

Creates a key that exists only in the current session. The key cannot be recovered after the session ends.

Use this parameter when you need a key only briefly, such as a wrapping key that encrypts, and then quickly decrypts, another key. Do not use a session key to encrypt data that you might need to decrypt after the session ends.

By default, keys that are generated are persistent (token) keys. Passing in <SESSION> changes this, ensuring a key generated with this argument is a session (ephemeral) key.

Required: No
