Function

This API is used to modify the information about a signature key.

Calling Method

For details, see Calling APIs.

URI

PUT /v2/{project_id}/apigw/instances/{instance_id}/signs/{sign_id}

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Project ID. For details about how to obtain it, see Obtaining a Project ID.

instance_id

Yes

String

Gateway ID, which can be obtained from the gateway information on the APIG console.

sign_id

Yes

Request Parameters

Table 2 Request header parameters

Parameter

Mandatory

Type

Table 3 Request body parameters

Parameter

Mandatory

Type

Description

name

Yes

String

Signature key name. It can contain letters, digits, and underscores(_) and must start with a letter.

Minimum: 3

Maximum: 64

sign_type

No

String

Signature key type.

  • hmac

  • basic

  • public_key

  • aes

To use a basic signature key, ensure that your gateway version supports it. If your gateway does not support this type of signature key, contact technical support to upgrade your gateway.

To use a public_key signature key, ensure that the public_key feature has been configured for your gateway. For details, see "Appendix" > "Supported Features". If your gateway does not support this feature, contact technical support to enable it.

To use an AES signature key, ensure that your gateway version supports it. If your gateway does not support this type of signature key, contact technical support to upgrade your gateway.

Enumeration values:

  • hmac

  • basic

  • public_key

  • aes

sign_key

No

String

Signature key.

  • hmac: The value contains 8 to 32 characters, including letters, digits, underscores (_), and hyphens (-). It must start with a letter or digit. If not specified, a key is automatically generated.

  • basic: The value contains 4 to 32 characters, including letters, digits, underscores (_), and hyphens (-). It must start with a letter. If not specified, a key is automatically generated.

  • public_key: The value contains 8 to 512 characters, including letters, digits, and special characters (_-+/=). It must start with a letter, digit, plus sign (+), or slash (/). If not specified, a key is automatically generated.

  • aes: The value contains 16 characters if the aes-128-cfb algorithm is used, or 32 characters if the aes-256-cfb algorithm is used. Letters, digits, and special characters (_-!@#$%+/=) are allowed. It must start with a letter, digit, plus sign (+), or slash (/). If not specified, a key is automatically generated.

sign_secret

No

String

Signature secret.

  • hmac: The value contains 16 to 64 characters. Letters, digits, and special characters (_-!@#$%) are allowed. It must start with a letter or digit. If not specified, a key is automatically generated.

  • basic: The value contains 8 to 64 characters. Letters, digits, and special characters (_-!@#$%) are allowed. It must start with a letter or digit. If not specified, a key is automatically generated.

  • public_key: The value can contain 16 to 2048 characters, including letters, digits, and special characters (_-!@#$%+/=). It must start with a letter, digit, plus sign (+), or slash (/). If not specified, a key is automatically generated.

  • aes: The value contains 16 characters, including letters, digits, and special characters (_-!@#$%+/=). It must start with a letter, digit, plus sign (+), or slash (/). If not specified, a key is automatically generated.

sign_algorithm

No

String

Signature algorithm. Specify a signature algorithm only when using an AES signature key. By default, no algorithm is used.

Enumeration values:

  • aes-128-cfb

  • aes-256-cfb
