Convergent Encryption and Why No One Uses It by vengefulduck

“Convergent encryption” allows for end-to-end encryption with server-side deduplication across all users’ data. The first time I heard about this, it sounded impossible.

Show HN: One-way encryption, my first Rust project by chrisdew

Turnstile encrypts data so that it can only be decrypted on another computer (and can’t be decrypted on the encrypting computer). Cryptographically, Turnstile is just a wrapper around libsodium’s box. Similar functionality could be acheived with an ECIES variant. Encrypting The source computer makes an ephemeral keypair. The source’s private key is used with the…
