atproto Cryptography Notes (Spring 2023)

Cryptography in atproto and did:plc

Public key cryptography is used in several aspects of atproto ("AT Protocol"). This short, informal, not-very-official document clarifies some details of which specific systems, keys, serialization formats, and signing/verification procedures are used.

For folks who are already familiar with atproto, the quick things to note are:

  • yes, it is expected for everybody to support two curve types
  • take the SHA-256 hash of repo commit nodes before signing/verifying them
  • depending on library/language used, p256 may have quirks with "compressed" encoding
  • yes, DID documents do require two similar-but-different encodings for public keys (did:web and multibase)
