Problems solved by technology

[0004] However, in the prior art, either the email is encrypted during transmission, and the plaintext of the email may be stored on the email server, which may cause a leak on the email server; or the terminal device needs to be encrypted and configured. After restricting the way the sending end sends e-mails, it is impossible to flexibly choose the protection method of e-mails, and the e-mails sent by the designated recipients cannot reflect the differentiated confidentiality requirements

Embodiment 1

[0032] figure 1 It is a flowchart of an email encryption method provided according to Embodiment 1 of the present invention. Such as figure 1 As shown, the encryption method of the email provided by the embodiment of the present invention comprises the following steps:

[0033]In step S101 , an encryption key of the email to be sent is obtained in response to a user's encryption operation on the email to be sent.

[0034] In this embodiment, in response to the encryption operation of the email to be sent by the user, the encryption key of the email to be sent can be obtained through a plug-in in the email sending and receiving system. In a specific implementation, when a user's request to send an email is received, an encryption decision interface is displayed to the user on the screen of the terminal device, so that the user can choose whether to encrypt the email to be sent according to the requirement. If the user chooses to encrypt the email to be sent according to requ...

Embodiment 2

[0052] figure 2 It is a flow chart of the email decryption method provided according to Embodiment 2 of the present invention. Such as figure 2 As shown, the decryption method of the email provided in this embodiment includes the following steps:

[0053] In step S201, a decryption key of the received email is acquired in response to a user's decryption operation on the received email.

[0054]In this embodiment, in response to the user's decryption operation on the received email, the decryption key of the received email can be obtained through a plug-in in the email sending and receiving system. In a specific embodiment, when the receiving end receives the encrypted email, the user opens the email to display the email subject name and encrypted content data. At the same time, it also gives a reminder that this email is an encrypted email and a link to decrypt the terminal device. Wherein, the link for decrypting the terminal device will be provided when the email sendi...

Embodiment 3

[0069] The embodiment of the present invention also provides an electronic device, which may be, for example, a mobile terminal, a personal computer (PC), a tablet computer, a server, and the like. Refer below image 3 , which shows a schematic structural diagram of an electronic device 300 suitable for implementing a terminal device or a server according to an embodiment of the present invention. Such as image 3 As shown, the electronic device 300 includes one or more first processors, a first communication element, etc., and the one or more first processors are, for example: one or more central processing units (CPU) 301, and / or one or a plurality of graphics processors (GPU) 313, etc., the first processor can be stored in the read-only memory (ROM) 302 in accordance with the executable instruction or loaded from the storage section 308 into the random access memory (RAM) 303 Various appropriate actions and processing are executed according to the instruction. In this em...

Abstract

The embodiment of the invention provides an email encryption and decryption method, a storage medium and an electronic device, and relates to the field of email communication. The email encryption anddecryption method comprises the following steps: in response to an encryption operation of a user to a to-be-sent email, obtaining an encryption key of the to-be-sent email; extracting content data and / or an attachment of the to-be-sent email, and encrypting the content data and / or the attachment according to the encryption key to obtain encrypted content data and / or attachment; and replacing thecontent data and / or the attachment of the to-be-sent email with the encrypted content data and / or attachment to obtain an encrypted email. By adoption of the email encryption and decryption method provided by the embodiment of the invention, the to-be-sent email can be encrypted according to the demand of the user, and different encryption demands can be provided for different emails sent to thesame receiver.

Description

technical field [0001] The embodiment of the present invention relates to the field of email communication, and in particular, relates to an email encryption and decryption method, a storage medium, and an electronic device. Background technique [0002] E-mail is a form of communication that provides for the exchange of information electronically and is the most widely used service on the Internet.
