Transmitting and receiving self-destructing messages

A method comprising:

• receiving, by a server and from a first device, a request to transmit a message to a user of a second device,
• the request to transmit the message including content of the message,
• the request to transmit the message including particular information indicating that the content of the message is to be displayed to the user for a particular amount of time,
• the particular information including:
• information identifying a type of the message as a self-destructing message, and information identifying the particular amount of time;
• encrypting, by the server and based on receiving the request to transmit the message, the content of the message to obtain an encrypted message,
• the content of the message being encrypted using a key,
• the key being generated based on the particular information;
• transmitting, by the server, the encrypted message to the second device;
• receiving, by the server and from the second device, a request for the key,
• the request for the key being received based on transmitting the encrypted message to the second device;
• and
• transmitting, by the server, information identifying the particular amount of time and the key to the second device after receiving the request for the key,
• the information identifying the particular amount of time and the key being transmitted to the second device to cause the second device to decrypt the encrypted message, using the key, to obtain a decrypted message and to cause the second device to delete the decrypted message after the particular amount of time following display of the decrypted message to the user.

A computer-readable medium storing instructions, the instructions comprising:

• one or more instructions which, when executed by one or more processors of a server, cause the one or more processors to:
• receive, from a first device, a request to transmit a message to a user of a second device,
• the request to transmit the message including content of the message,
• the request to transmit the message including particular information indicating that the content of the message is to be displayed to the user for a particular amount of time,
• the particular information including:
• information identifying a type of the message as a self-destructing message, and information identifying the particular amount of time;
• encrypt, based on receiving the request to transmit the message, the content of the message to obtain an encrypted message,
• the content of the message being encrypted using a key,
• the key being generated based on the particular information;
• transmit a link to the encrypted message to the second device;
• receive, from the second device, a request for a decrypted message corresponding to the encrypted message,
• the request for the decrypted message being received based on transmitting the link to the encrypted message;
• decrypt the encrypted message to obtain the decrypted message based on receiving the request for the decrypted message,
• the encrypted message being decrypted using the key;
• transmit the decrypted message to the second device based on receiving the request for the decrypted message;
• and
• cause the decrypted message to be removed from a display of the second device after the particular amount of time.
