IiDSrSSKrSSKrSSKJr SSKJr "SS5rg)zj Provides AWS4SigningKey class for generating Amazon Web Services authentication version 4 signing keys. N)warn)datetimec\\rSrSrSrS Sjr\S Sj5r\S5r \ S5r Sr g) AWS4SigningKeya AWS signing key. Used to sign AWS authentication strings. The secret key is stored in the instance after instantiation, this can be changed via the store_secret_key argument, see below for details. Methods: generate_key() -- Generate AWS4 Signing Key string sign_sha256() -- Generate SHA256 HMAC signature, encoding message to bytes first if required Attributes: region -- AWS region the key is scoped for service -- AWS service the key is scoped for date -- Date the key is scoped for scope -- The AWS scope string for this key, calculated from the above attributes key -- The signing key string itself amz_date -- Deprecated name for 'date'. Use the 'date' attribute instead. amz_date will be removed in a future version.

[, store_secret_key]) secret_key -- This is your AWS secret access key region -- The region you're connecting to, as per list at http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region e.g. us-east-1. For services which don't require a region (e.g. IAM), use us-east-1. service -- The name of the service you're connecting to, as per endpoints at: http://docs.aws.amazon.com/general/latest/gr/rande.html e.g. elasticbeanstalk date -- 8-digit date of the form YYYYMMDD. Key is only valid for requests with a Date or X-Amz-Date header matching this date. If date is not supplied the current date is used. store_secret_key -- Whether the secret key is stored in the instance. By default this is True, meaning the key is stored in the secret_key property and is available to any code the instance is passed to. Having the secret key retained makes it easier to regenerate the key if a scope parameter changes (usually the date). This is used by the AWS4Auth class to perform its automatic key updates when a request date/scope date mismatch is encountered. If you are passing instances to untrusted code you can set this to False. This will cause the secret key to be discarded as soon as the signing key has been generated. Note though that you will need to manually regenerate keys when needed (or if you use the regenerate_key() method on an AWS4Auth instance you will need to pass it the secret key). All arguments should be supplied as strings. z%Y%m%dz{}/{}/{}/aws4_requestN) regionservicerutcnowstrftimedateformatscopestore_secret_key secret_key generate_keykey)selfrr r r rs F/venv/lib/python3.13/site-packages/requests_aws4auth/aws4signingkey.py__init__AWS4SigningKey.__init__)sT  @HOO-66x@ ,33DIIt{{DLLY 0(,(=(=*4$$ZdllDIIVcSU-RS5nURXd5nURXr5nURX5n URU S5n U(aXX4$U $)a Generate the signing key string as bytes.
