Make the key algorithm and key size of new context keystores configur… - #8333

…able The context keystore key pair was always generated as RSA-2048. Read the key algorithm and key size from [keystore.tenant] key_algorithm and key_size through the shared KeystoreUtils getters in carbon-kernel. The default stays RSA-2048, and the setting applies only to keystores created after it is set. An invalid value fails the keystore generation with the validation message, before any keystore is created. It never falls back to a smaller key. Add tests that generate a real context keystore in memory and check the key size, the validation of invalid key configuration, the certificate signature algorithm and the self-signed certificate.
📝 WalkthroughWalkthroughContext keystore generation now uses the tenant key algorithm and size from configuration instead of fixed RSA-2048 settings. Configuration errors are wrapped in ChangesTenant context keystore generation
Priority: ⬇️ Low Change: Feature Merge Risk: 🔵 Low · up to Keystore generation has no established functional failure, but the license headers and successful-generation logging need correction. These are bounded issues rather than a material obstacle to merging. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to Existing keystores retain their keys, and configuration is resolved before new key material is generated or submitted for persistence. No introduced security weakness was established. However, the deployed dependency must provide the expected validation and compatible methods; that runtime contract could not be verified.

Log successful context-keystore persistence.
When no keystore exists, generateKeyStore can generate the key pair and persist the keystore without an INFO completion log. Add the log only after keyStoreManager.addKeyStore succeeds. The existing already-available branch logs a warning and returns without adding the keystore.
🐛 Suggested fix
keyStoreManager.addKeyStore(outputStream.toByteArray(), keyStoreName,
passwordChar, " ", KeystoreUtils.getKeyStoreFileType(tenantDomain), passwordChar);
+ LOG.info("Generated and persisted context keystore: " + keyStoreName);🤖 Prompt for AI Agents

Proposed changes in this pull request
IdentityKeyStoreGeneratorImplcreates tenant context keystores with a hardcoded RSA-2048 key. An example is thecookiekeystore that adaptive scriptsetCookie/getCookieuse to sign and validate cookies. Some deployments may need to use keys with different sizes.This PR makes the key algorithm and key size configurable for newly created context keystores. It uses the same configuration and validation as tenant keystores.
