-The purpose of this NIP is to allow an organization and classification of shared files. So that relays can filter and organize in any way that is of interest. With that, multiple types of filesharing clients can be created. NIP-94 support is not expected to be implemented by "social" clients that deal with kind:1 notes or by longform clients that deal with kind:30023 articles.

 ## Event format
 
 This NIP specifies the use of the `1063` event type, having in `content` a description of the file content, and a list of tags described below:
 
 * `url` the url to download the file
 * `m` a string indicating the data type of the file. The [MIME types](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Common_types) format must be used, and they should be lowercase.
-* `"aes-256-gcm"` (optional)  key and nonce for AES-GCM encryption with tagSize always 128bits
 * `x` containing the SHA-256 hexencoded string of the file.
 * `size` (optional) size of file in bytes
 * `dim` (optional) size of file in pixels in the form `<width>x<height>`
