+# flexibleengine_apig_signature
+
+Manages a signature resource within FlexibleEngine.
+
+## Example Usage
+
+### Create a signature of the HMAC type
+
+```hcl
+variable "instance_id" {}
+variable "signature_name" {}
+variable "signature_key" {}
+variable "signature_secret" {}
+
+resource "flexibleengine_apig_signature" "test" {
+  instance_id = var.instance_id
+  name        = var.signature_name
+  type        = "hmac"
+  key         = var.signature_key
+  secret      = var.signature_secret
+}
+```
+
+### Create a signature and automatically generate key and secret
+
+```hcl
+variable "instance_id" {}
+variable "signature_name" {}
+
+resource "flexibleengine_apig_signature" "test" {
+  instance_id = var.instance_id
+  name        = var.signature_name
+  type        = "hmac"
+}
+```
+
+### Create a signature of the AES type
+
+```hcl
+variable "instance_id" {}
+variable "signature_name" {}
+variable "signature_key" {}
+variable "signature_secret" {}
+
+resource "flexibleengine_apig_signature" "test" {
+  instance_id = var.instance_id
+  name        = var.signature_name
+  type        = "aes"
+  algorithm   = "aes-128-cfb"
+  key         = var.signature_key
+  secret      = var.signature_secret
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String, ForceNew) Specifies the region where the signature is located.  
+  If omitted, the provider-level region will be used. 
+  Changing this will create a new resource.
+
+* `instance_id` - (Required, String, ForceNew) Specifies the ID of the dedicated instance to which the signature
+  belongs.  
+  Changing this will create a new resource.
+
+* `name` - (Required, String) Specifies the signature name.  
+  The valid length is limited from `3` to `64`, only English letters, Chinese characters, digits and underscores (_) are
+  allowed. The name must start with an English letter or Chinese character.
+
+* `type` - (Required, String) Specifies the type of signature.  
+  The valid values are as follows:
+  + **basic**: Basic auth type.
+  + **hmac**: HMAC type.
+  + **aes**: AES type
+
+* `key` - (Optional, String) Specifies the signature key.  
+  + For `basic` type: The value contains `4` to `32` characters, including letters, digits, underscores (_) and
+    hyphens (-). It must start with a letter.
+  + For `hmac` type: The value contains `8` to `32` characters, including letters, digits, underscores (_) and
+    hyphens (-). It must start with a letter or digit.
+  + For `aes` type: The value contains `16` characters if the `aes-128-cfb` algorithm is used, or `32` characters if the
+    `aes-256-cfb` algorithm is used. Only letters, digits, and special characters (`_-!@#$%+/=`) are allowed.
+    It must start with a letter, digit, plus sign (+), or slash (/).
+
+  If not specified, the key will automatically generated. The auto-generation is only supported on first creation.  
+
+* `secret` - (Optional, String) Specifies the signature secret.  
+  If not specified, the secret will automatically generated. The auto-generation is only supported on first creation.  
+
+* `algorithm` - (Optional, String) Specifies the signature algorithm.  
+  This parameter is required and only available when signature `type` is `aes`.  
+  The valid values are as follows:
+  + **aes-128-cfb**
+  + **aes-256-cfb**
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The ID of the signature.
+
+* `created_at` - The creation time of the signature.
+
+* `updated_at` - The latest update time of the signature.
+
+## Import
+
+Signatures can be imported using their `id` and related dedicated instance ID, separated by a slash, e.g.
+
+```bash
+$ terraform import flexibleengine_apig_signature.test <instance_id>/<id>
+```

+
+# flexibleengine_apig_signature_associate
+
+Use this resource to bind the APIs to the signature within FlexibleEngine.
+
+-> A signature can only create one `flexibleengine_apig_signature_associate` resource.
+   And a published ID for API can only bind a signature.
+
+## Example Usage
+
+```hcl
+variable "instance_id" {}
+variable "signature_id" {}
+variable "api_publish_ids" {
+  type = list(string)
+}
+
+resource "flexibleengine_apig_signature_associate" "test" {
+  instance_id  = var.instance_id
+  signature_id = var.signature_id
+  publish_ids  = var.api_publish_ids
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String, ForceNew) Specifies the region where the signature and the APIs are located.  
+  If omitted, the provider-level region will be used. Changing this will create a new resource.
+
+* `instance_id` - (Required, String, ForceNew) Specifies the ID of the dedicated instance to which the APIs and the
+  signature belong.  
+  Changing this will create a new resource.
+
+* `signature_id` - (Required, String, ForceNew) Specifies the signature ID for APIs binding.  
+  Changing this will create a new resource.
+
+* `publish_ids` - (Required, List) Specifies the publish IDs corresponding to the APIs bound by the signature.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - Resource ID. The format is `<instance_id>/<signature_id>`.
+
+## Import
+
+Associate resources can be imported using their `signature_id` and the APIG dedicated instance ID to which the signature
+belongs, separated by a slash, e.g.
+
+```bash
+$ terraform import flexibleengine_apig_signature_associate.test <instance_id>/<signature_id>
+```
