Obtaining Key Import Parameters

Function

This API is used to obtain the parameters required for importing keys, including import passwords and encryption public keys.

An RSA_2048 public key is returned by default.

Calling Method

For details, see Calling APIs.

URI

POST /v1.0/{project_id}/kms/get-parameters-for-import

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token. It can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is the user token.

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
key_id	Yes	String	A 36-byte key ID which matches the regular expression ^[0-9a-z]{8}-[0-9a-z]{4}-[0-9a-z]{4}-[0-9a-z]{4}-[0-9a-z]{12}$, for example, 0d0466b0-e727-4d9c-b35d-f84bb474a37f.
wrapping_algorithm	Yes	String	Key material encryption algorithm. Possible values are as follows: RSAES_OAEP_SHA_256 SM2_ENCRYPT. Some sites cannot be imported using this algorithm.
sequence	No	String	A 36-byte serial number of a request message, for example, 919c82d4-8046-4722-9094-35c3c6524cff
