Encryption flow of sent messages

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.

Receiving messages

After a message is successfully sent, the recipient is notified via automated email that a secure message from the sender is waiting for them at Secure Messages.
