Mike Gillan enhanced the rclone/rclone repository by developing a secure SRP-based authentication flow for iCloud Drive, replacing deprecated plaintext sign-in while maintaining compatibility with Apple’s two-factor authentication. Using Go, he implemented a multi-step handshake based on RFC 5054 with 2048-bit groups and SHA-256, updating request metadata to meet Apple’s evolving requirements. In addition to building the new authentication feature, Mike addressed a critical edge case by normalizing Apple IDs to lowercase before SRP proof computation, resolving failures caused by mixed-case input. His work demonstrated depth in backend development, cryptography, and API integration, resulting in improved reliability and security.
March 2026: Fixed a critical SRP authentication edge-case in rclone/rclone by normalizing Apple IDs to lowercase before client-side SRP proof computation, ensuring the M1 hashes match regardless of input case. This eliminated sign-in failures caused by mixed-case IDs, improving reliability for iCloud drive users and reducing support load. No new features released this month; priority was robustness and correctness of the authentication flow. Commit: 4a00a4dc4bbf21aa6f112036c644701968c7234b.
