Go server for two-man rule style file encryption and decryption.
Role in this project:Back-end Developer
Back-end DeveloperContributions:1 review, 80 commits, 98 PRs in 2 years 11 months
Contributions summary:Kyle's contributions primarily focused on adding support for Elliptic Curve Cryptography (ECC) to the "redoctober" project, a Go server for file encryption. This involved implementing ECC key generation, encryption, and decryption functionality within the `passvault` and `ecdh` packages. The user also refactored existing code to accommodate the new ECC support, ensuring compatibility with existing RSA-based encryption methods. These changes enhanced the project's cryptographic capabilities and flexibility.
