Description

This PR adds support for HmacSHA512 when the API server verifies the signature of signed API requests (apiKey/secretKey authentication). Until now only HmacSHA1 was accepted.

Behaviour change

• ApiServer.verifyRequest() computes the expected signature with HmacSHA512 first, then falls back to HmacSHA1. The request is accepted if either matches.
• New global setting api.legacy.algorithm.supported (Advanced, global scope, dynamic, default true):
  • true: both HmacSHA512 and HmacSHA1 are accepted, so existing clients (CloudMonkey, cloudstack-go, Terraform provider and other third-party tools) keep working unchanged.
  • false: only HmacSHA512 is accepted. Requests signed with HmacSHA1 are rejected.
• The signature computation moved into a helper, getComputedSignature(algorithm, secretKey, unsignedRequest), and the algorithm names are defined in the new com.cloud.utils.security.Algorithms class.
• A failed comparison is logged once per algorithm tried (the sanitised user signature is logged, as before).
• The explicit Security.addProvider(new BouncyCastleProvider()) in ApiServer.init() is removed. The Mac lookups here only use the default JCE providers.

Compatibility

The default (true) keeps full backward compatibility. Operators can set api.legacy.algorithm.supported=false once all their API clients sign with HmacSHA512.

Signing with HmacSHA512 is not applied on the client side by this PR. Client tools have to be updated to sign with it before the legacy algorithm can be disabled.

How Has This Been Tested?

Test plan (to be run against a management server with this change):

• Request signed with HmacSHA1, api.legacy.algorithm.supported=true (default): accepted
• Request signed with HmacSHA512, api.legacy.algorithm.supported=true: accepted
• Request signed with HmacSHA512, api.legacy.algorithm.supported=false: accepted
• Request signed with HmacSHA1, api.legacy.algorithm.supported=false: rejected (HTTP 401 / "unable to verify user credentials")
• Request with a wrong signature: rejected with either setting
• Changing the setting takes effect without restarting the management server
• Root CA, SSL certificate upload and other BouncyCastle-dependent features still work after removing the provider registration from ApiServer

How did you try to break this feature and the system with this change?
