分享数据大小或格式无效

Error message

分享数据大小或格式无效

What it means

Thrown by decrypt_shared_payload when the envelope's crypto dimensions are wrong: the base64-decoded key is not 32 bytes, the IV not 12 bytes, or the ciphertext exceeds MAX_ROLLOUT_BYTES + 16 (AES-GCM tag). The offending inputs are the k= key fragment and the iv/ciphertext fields of the share record; this guard runs before the AES-256-GCM cipher is constructed.
