Configure authentication against a system

Edit online

The CSO API supports AWS Signature v2 and v4 Authentication on an IBM Cloud Object Storage System™.

The AWS Signature v4 signing specification describes how to add authentication information to S3 requests.

Requests that use AWS authentication must be signed by using the requesting user’s access key ID and secret access key, collectively known as access credentials.

The order of precedence for access credentials is:
  1. Credentials that are passed as BasicAWSCredentials instance parameters.
  2. Credentials set as environment variables.
  3. Credentials set as JVM system properties.
  4. Credentials set in AwsCredentials.properties file.
  5. Credentials set in the shared credentials file.
