Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation
ecs:DescribeKeyPairs	get	KeyPair `acs:ecs:{#regionId}:{#accountId}:keypair/{#keypairName}` KeyPair `acs:ecs:{#regionId}:{#accountId}:keypair/*`	none	none

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The region ID of the key pair. You can call the DescribeRegions operation to query the most recent region list.	cn-hangzhou
KeyPairName	string	No	The name of the key pair. You can use the asterisk () symbol as a wildcard in regular expressions to perform a fuzzy search for key pairs. Sample patterns: `SshKey`: queries key pairs whose names end with SshKey, including the key pair named SshKey. `SshKey`: queries key pairs whose names start with SshKey, including the key pair named SshKey. `SshKey*`: queries key pairs whose names include SshKey, including the key pair named SshKey. `SshKey`: queries the key pair named SshKey.	SshKey
KeyPairFingerPrint	string	No	The fingerprint of the key pair. The message-digest algorithm 5 (MD5) is used based on the public key fingerprint format defined in RFC 4716. For more information, see RFC 4716.	ABC1234567
PageNumber	integer	No	The number of the page to return. Pages start from page 1. Default value: 1.	1
PageSize	integer	No	The number of entries to return on each page. Maximum value: 50. Default value: 10.	10
IncludePublicKey	boolean	No	Specifies whether to include PublicKey in the response. Default value: false.	false
ResourceGroupId	string	No	The ID of the resource group. If this parameter is specified to query resources, up to 1,000 resources that belong to the specified resource group can be displayed in the response. Note Resources in the default resource group are displayed in the response regardless of how this parameter is set.	rg-amnhr7u7c7hj****
Tag	array<object>	No	The tags.
	object	No
Key	string	No	The key of tag N of the key pair. Valid values of N: 1 to 20. If a single tag is specified to query resources, up to 1,000 resources that are bound with this tag can be displayed in the response. If multiple tags are specified to query resources, up to 1,000 resources that are bound with all these tags can be displayed in the response. To query more than 1,000 resources that have specified tags added, call the ListTagResources operation.	TestKey
Value	string	No	The value of tag N of the key pair. Valid values of N: 1 to 20.	TestValue

Response parameters

PageNumber	integer	The page number of the returned page.	1
TotalCount	integer	The total number of key pairs.	1
KeyPairs	array<object>	The information of the key pairs.
KeyPair	object
CreationTime	string	The time when the key pair was created.	2023-09-04T08:33Z
KeyPairName	string	The name of the key pair.	testKeyPairName
KeyPairFingerPrint	string	The fingerprint of the key pair.	ABC1234567
ResourceGroupId	string	The ID of the resource group.	rg-amnhr7u7c7hj****
PublicKey	string	The content of the public key.	ssh-rsa****
Tags	array<object>	The tags of the key pair.
Tag	object
TagValue	string	The tag value of the key pair.	TestValue
TagKey	string	The tag key of the key pair.	TestKey
