Encrypt messages that can only be decrypted after a specific time. Powered by drand timelock encryption and stored on your atproto PDS.
Time-lock puzzle
A time-lock puzzle, or time-released cryptography, encrypts a message that cannot be decrypted until a specified amount of time has passed. The concept was first described by Timothy C. May,[1] and a solution first introduced by Ron Rivest, Adi Shamir, and David A. Wagner in 1996.[2] Time-lock puzzle are useful in cases where confidentiality of information is determined by time, such as a diarist who does not want their views released until 50 years after their death, an auction where bids are sealed until the bidding period is closed, electronic voting, and contract signing.[1][3] They can additionally be used in creating further cryptographic primitives, such as verifiable delay functions and zero knowledge proofs.[3]
Permissioned Data Diary 1: To Encrypt or Not to Encrypt - Daniel's Leaflets
The first in a series of posts about major design decisions along the way to a permissioned data protocol for atproto.

Robustly-secured data that can surprisingly vanish at a moments notice.
VeraCrypt - Free Open source disk encryption with strong security for the Paranoid
VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files.
Adversarial ATProto PDS Migration | Blog
An ATProto account lives on a Personal Data Server (PDS), and that service needs to be hosted somewhere by someone. There are a lot of options here, like a Raspberry Pi in your closet, a rented VPS in a datacentre, or a batteries-included service like bsky.social.
FiloSottile/age
A simple, modern and secure encryption tool (and Go library) with small explicit keys, no config options, and UNIX-style composability.
DropLock
The link below is like an open lock box that belongs to you. Anyone you share it with can put a secret inside and create a locked link that only you can open.
Whisper - keith.is
End-to-end encrypted P2P chat using Iroh and Bluesky identity. No servers, no logs. Your ATProto DID is your address book, Iroh handles the rest.
Ente Locker
Store your important documents and credentials. Share them with trusted contacts or pass them on in emergencies.
Unlocking Quantum-Encrypted Group Chats for ATProto on XMTP
Developers building with ATProto (the protocol powering Bluesky) have been asking how they can use XMTP to power messaging between users in their apps. Itโs possible today to add secure messaging to any Bluesky app, and to add Bluesky identity to any messenger built on XMTP. 0:00 /0:
Cryptographic Nature
I consider the many ways in which evolved information-flows are restricted and metabolic resources protected and hidden -- the thesis of living phenomena as evolutionary cryptosystems. I present the information theory of secrecy systems and discuss mechanisms acquired by evolved lineages that encrypt sensitive heritable information with random keys. I explore the idea that complexity science is a cryptographic discipline as "frozen accidents", or various forms of regularized randomness, historically encrypt adaptive dynamics.
want to confess something but dont let people know right now? or write a post to your future self that only opens at a certain time? secrets.atmo.social note that all data is public (but can only be viewed after the date you set)
