Abstract

The invention provides an encrypted storage method and an encrypted storage device. The method comprises the steps of calculating the salted Hash value of a plaintext password, combining the salted Hash value and a corresponding random salt value according to a preset rule to get a ciphertext password corresponding to the plaintext password, and storing the ciphertext password. Through the technical scheme of the invention, the difficulty in ciphertext password cracking is improved, and the safety of user accounts is guaranteed.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an encrypted storage method and device. Background technique [0002] With the development of Internet technology, people pay more and more attention to data security. In view of the irreversibility of the hash operation, the server usually performs hash operation on the user's plaintext password, and then stores the ciphertext password obtained after the hash operation, so as to ensure the security of the user account. [0003] However, hackers can use the rainbow table technology to crack the ciphertext password, for example: by storing a small reversible long-chain password hash value, according to the ciphertext password, the corresponding plaintext password is cracked, which brings user accounts Great security risk. Contents of the invention [0004] In view of this, the present application provides an encrypted storage method and device. [0005] S...
