Work with the URL-based storage and compression system.
blocks → serializeBlocks (binary + compact props) → CompressionStream (deflate or brotli) → format byte + Base85 → URL hash
| Format byte | Encoding | Compression |
|---|---|---|
| (legacy) | base64url | deflate-raw |
| 0x01 | base64url | deflate-raw |
| 0x02 | base85 | deflate-raw |
| 0x03 | base85 | encrypted (AES-GCM) |
| 0x04 | base85 | brotli |
Format detection: if hash contains chars outside base64url (A-Za-z0-9_-), it's base85. Otherwise legacy base64url.
Block properties use short keys when serialized:
lang → lchecked → cstart → semoji → edepth → dAES-GCM-256 with PBKDF2 key derivation (120k iterations). Payload: salt(12) + IV(12) + ciphertext+tag(16). Triggered via "Lock with password" in Share menu.
