PHP Class Emarref\Jwt\HeaderParameter\Algorithm
The "alg" (algorithm) Header Parameter identifies the cryptographic algorithm used to secure the JWS. The JWS
Signature value is not valid if the "alg" value does not represent a supported algorithm, or if there is not a key
for use with that algorithm associated with the party that digitally signed or MACed the content. "alg" 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 "alg" value is a case-sensitive string containing a StringOrURI value.
This Header Parameter MUST be present and MUST be understood and processed by implementations.
A list of defined "alg" values for this use can be found in the IANA JSON Web Signature and Encryption Algorithms
registry defined in [JWA]; the initial contents of this registry are the values defined in Section 3.1 of the JSON
Web Algorithms (JWA) [JWA] specification.
