Bintray Premium accounts offer features tailored for commercial software distribution, including private repositories, fine-grained permission management, and storage flexibility. A key feature for managing access to artifacts is the Signed URL, which allows users to share files from private repositories with anyone, even those without a Bintray account, through a unique URL. This URL can be configured to expire after a certain time or be revoked at any moment, ensuring controlled access. Creating a Signed URL involves using a REST API call, which utilizes a unique pair of internal private and public keys for encryption and decryption. By default, the signed URL is valid for 24 hours, but this duration can be adjusted through a JSON configuration. More information on this API can be found in the Bintray REST API documentation, highlighting the simplicity and control offered for distributing artifacts securely.
