AWS Signature v4 support #3
Description
Why: AWS APIs use HMAC-based per-request signing (Sig v4), not static Bearer tokens. Each request must be signed with the secret key, region, service name, and timestamp.
Scope:
- Built-in AWS Sig v4 signer
- Store AWS Access Key ID + Secret Access Key
- Auto-sign requests to any AWS service
Use cases:
- S3, DynamoDB, SES, Lambda, EC2 API calls
- Amazon Seller Central SP-API (also needs OAuth2 + Sig v4)
Priority: Medium — AWS is ubiquitous but the signing is complex
