# PublicKeyConfigProperty

Configuration information about a public key that you can use with [signed URLs and signed cookies](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/PrivateContent.html) , or with [field-level encryption](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/field-level-encryption.html) .

CloudFront supports signed URLs and signed cookies with RSA 2048 or ECDSA 256 key signatures. Field-level encryption is only compatible with RSA 2048 key signatures.
