Abstract

The invention discloses a mail attachment processing method and a mail attachment processing device. The method comprises the steps that an attachment is encrypted to acquire an encrypted file; a plaintext abstract of the attachment is computed; whether the plaintext abstract exists on a server is detected; the encrypted file is divided into a plurality of subfiles according to a preset size under the condition that the plaintext abstract does not exist on the server; and all the subfiles are uploaded to the server. According to the method and the device, the mail attachment can be uploaded to the server after encrypted, so that the problem that a secret is divulged due to the fact that the plaintext sendmail attachment has risks of being divulged and browsed is solved, encrypted uploading and sending of the oversized attachment are achieved, the attachment can be transmitted safely, and the secret of a mail is prevented from being divulged.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and device for processing mail attachments. Background technique [0002] With the popularity of the Internet, using e-mail to send attachments has become one of the most commonly used ways of sharing files in modern people's life and work. However, emails in the prior art are transmitted and stored in clear text on the network, so that personal privacy and company secrets may be intercepted and browsed at any time. In addition, when the attachment is large, the email solution based on MTA will Faced with problems such as transmission timeout and the other party's server being unable to receive. [0003] Aiming at the risk of interception and browsing of email attachments sent in plain text in the prior art, resulting in leakage of secrets, no effective solution has been proposed so far. Contents of the invention [0004] Aiming at the risk of interception and browsing...
