Encryption flow of sent messages

When a message is sent, the following encryption flow process occurs:

1. All messages, including attachments, are securely transmitted to the Coro servers. This ensures that the data is encrypted during transmission to the servers.
2. After a message is received by the server, the content and attachments are encrypted using Advanced Encryption Standard (AES).

   note

   To learn more about AES, see What is the Advanced Encryption Standard (AES)?

3. The encrypted message and attachments are stored in Coro's internal database, which only authorized users can access. The encrypted attachments are stored separately in an Amazon S3 bucket, which is a secure storage service that adds an additional layer of security to protect sensitive files.

For further information on the decryption flow followed when a message is received, see Decryption flow of received messages.
