trillian is a transparent, cryptographically verifiable data store built on Merkle trees that provides append-only logs and verifiable key–value maps. It separates a storage layer from a verifiability layer, letting applications prove inclusion, consistency, and non-existence through compact cryptographic proofs. The system is designed for horizontal scale with gRPC APIs, enabling multiple frontends and sequencers to operate over a shared backend. Common use cases include certificate transparency, package registries, and audit logs where public verifiability or tamper evidence is required. ...

Vigen is a Unicode UTF-8 multi-pass rotation encryption system based on the classic Tableau de Vigenère. Vigen is an experiment using this particular cypher, intended for those who are interesting in building their own encryption tables. Vigen can generate exceedingly strong rotation cyphers that are probably unbreakable without the given keys and tables. Vigen might even generate military grade cyphers, although I make no claim as to the security of the cypher. Vigen is for encrypting UTF-8...
