Method: Cloudinary::Utils.api_sign_request

Defined in:
lib/cloudinary/utils.rb

.api_sign_request(params_to_sign, api_secret, signature_algorithm = nil, signature_version = nil) ⇒ String

Signs API request parameters

Parameters:

  • params_to_sign (Hash) —

    Parameters to include in the signature

  • api_secret (String) —

    API secret for signing

  • signature_algorithm (Symbol|nil) (defaults to: nil) —

    Hash algorithm to use (:sha1 or :sha256)

  • signature_version (Integer|nil) (defaults to: nil) —

    Version of signature algorithm to use:

    • Version 1: Original behavior without parameter encoding

    • Version 2+ (default): Includes parameter encoding to prevent parameter smuggling

Returns:

  • (String) —

    Hexadecimal signature
