NetSparkle is a C#, cross-platform, highly-configurable software update framework with pre-built UI for .NET developers compatible with .NET 4.6.2/.NET 6+, WinForms, WPF, and Avalonia; uses Ed25519 signatures. View basic usage here in the README and try the samples for yourself.
JS library for verifying JWTs signed by Amazon Cognito, and any OIDC-compatible IDP that signs JWTs with RS256, RS384, RS512, ES256, ES384, ES512, Ed25519 and Ed448
Cryptographic signature algorithms: DSA, ECDSA, Ed25519
End-to-end encrypted notes, tasks, files, passwords, journal and bookmarks. Keyed by a 12-word BIP-39 phrase: no email, no password, no account to leak. The full client source for web, desktop and mobile is published, along with the encryption (XChaCha20-Poly1305, HKDF-SHA256, Ed25519) and the threat model, so the privacy claims are falsifiable.
