      options: GroupMediaServiceOptions<TMedia>,

  Parameters

Readonlymedia

decryptMedia

• decryptMedia(
      encrypted: Uint8Array,
      attachment: MediaAttachment,
  ): Promise<StoredMedia>

  Decrypts a fetched blob for a parsed attachment, verifying its ciphertext and plaintext hashes, and caches the plaintext keyed by ciphertextSha256.

  Parameters

  • encrypted: Uint8Array
  • attachment: MediaAttachment

  Returns Promise<StoredMedia>

encryptMedia

• encryptMedia(
      blob: Blob,
      metadata: EncryptMediaMetadata,
  ): Promise<{ attachment: MediaAttachment; encrypted: Uint8Array }>

  Encrypts a blob for sharing in a group message. The returned attachment has its hashes, nonce, media type, and filename set but no locators — the caller uploads encrypted to a blob store, adds a MediaAttachment locator, then serializes it with encodeMediaImetaTag.

  Parameters

  • blob: Blob
  • metadata: EncryptMediaMetadata

  Returns Promise<{ attachment: MediaAttachment; encrypted: Uint8Array }>
