KdbxWeb: KeePass KDBX Database Reader/Writer

KdbxWeb is a high-performance JavaScript library for reading and writing KeePass v2 databases, specifically supporting Kdbx3 and Kdbx4 file formats. It functions seamlessly in both Node.js environments and modern web browsers, maintaining a compact size of approximately 130kB including its internal dependencies. Key features include fast encryption powered by WebCrypto, secure in-memory handling of protected values using XORing, and robust capabilities for conflict-free merging of database states. While offering comprehensive Kdbx feature support, it's crucial to note that the library does not support older KeePass v1 `.kdb` files. For Kdbx4 files utilizing Argon2, users are required to provide their own Argon2 implementation, as it's not bundled to allow for optimal platform-specific performance choices. The current stable version is 2.1.1, with releases typically following development needs rather than a fixed cadence.
