!!! Overview
[{$pagename}] is an [Abbreviation] of [Encryption].


!! [{$pagename}] [JSON Web Encryption]
The [{$pagename}] ([encryption] [algorithm]) Header Parameter identifies the content [encryption] [algorithm] used to perform [authenticated] [encryption] on the [Plaintext|message] to produce the [Ciphertext] and the [Authentication] Tag. This [algorithm] [MUST] be an [AEAD] algorithm with a specified key length. The encrypted content is not usable if the enc value does not represent a supported [algorithm]. [{$pagename}] values should either be registered in the [IANA] [JSON Web Signature and Encryption Algorithms] registry defined in [JWA] or be a value that contains a [Collision-Resistant Name]. 

The [{$pagename}] value is a [case-sensitive] [ASCII] string containing a [StringOrURI] value. This Header Parameter [MUST] be present and [MUST] be understood and processed by implementations.

A list of defined [{$pagename}] values for this use can be found in the [IANA Registry] "[JSON Web Signature and Encryption Algorithms]" registry established by [JWA]; the initial contents of this registry are the values defined in Section 5.1 of [JWA].
