 ## Summary
 
 This package provides a `confmap.Provider` implementation for symmetric AES encryption of credentials (and other sensitive values) in configurations. It relies on the environment variable `OTEL_AES_CREDENTIAL_PROVIDER` set to the value of the AES key, base64 encoded. 16, 24, or 32 byte keys are supported, selecting AES-128, AES-192, or AES-256 respectively.
