+  Get information on a SSH public key associated with the specified IAM user.
+---
+
+# Data Source: aws_iam_user_ssh_key
+
+Use this data source to get information about a SSH public key associated with the specified IAM user.
+
+## Example Usage
+
+```terraform
+data "aws_iam_user_ssh_key" "example" {
+  encoding          = "SSH"
+  ssh_public_key_id = "APKARUZ32GUTKIGARLXE"
+  username          = "test-user"
+}
+```
+
+## Argument Reference
+
+* `encoding` - (Required) Specifies the public key encoding format to use in the response. To retrieve the public key in ssh-rsa format, use `SSH`. To retrieve the public key in PEM format, use `PEM`.
+* `ssh_public_key_id` - (Required) The unique identifier for the SSH public key.
+* `username` - (Required) The name of the IAM user associated with the SSH public key.
+
+## Attributes Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `fingerprint` - The MD5 message digest of the SSH public key.
+* `public_key` - The SSH public key.
+* `status` - The status of the SSH public key. Active means that the key can be used for authentication with an CodeCommit repository. Inactive means that the key cannot be used.
