	AWSV4Signer (const std::string & access_key, const std::string & secret_key, const std::string & region, const std::string & session_token="")
const std::string &	getSessionToken () const
std::string	signRequest (const std::string & method, const std::string & bucket, const std::string & key, const std::string & content_hash, const std::map< std::string, std::string > & headers) const Sign an S3 request using AWS Signature Version 4.

Public Static Functions¶

Type	Name
std::string	hexEncode (const unsigned char * data, size_t len) Convert binary data to hex string (public utility).

Detailed Description¶

Implements AWS SigV4 authentication for S3 requests. Uses OpenSSL for the SHA-256 / HMAC-SHA256 primitives on native builds and mbedTLS under WebAssembly (see the s3crypto shim above). This provides authentication without requiring the full AWS SDK.
