Problems solved by technology

The method of increasing the complexity and length of the password is effective, but it is not easy for users to remember; and if the length of the password is increased by "adding salt", once the "salt" is leaked, the plaintext may also be cracked

Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] The main solution of the embodiment of the present invention is: when an encryption request is received, obtain the target character string to be encrypted; replace each character in the target character string with a corresponding random character string according to the first mapping relationship; The replaced random strings are concatenated to generate encrypted strings.

[0047] Since the string is encrypted by increasing the complexity and length of the password, it is not easy for the user to remember; the method of "adding salt" encryption may also be cracked. Therefore, the present invention provides a solution, aiming to provide an encryption method that does not increase the user's memory burden, and at the same time increases the difficulty of cracking.

[0048] like figure 1 as shown, figure 1 It...

Abstract

The invention discloses a character string encryption method. The method comprises the following steps: when an encryption request is received, obtaining a to-be-encrypted target character string; replacing the characters in the target character string with corresponding random character strings according to a pre-established first mapping relation; and splicing the replaced random character strings to generate an encrypted character string. The invention further discloses a character string encryption method and apparatus, and a computer readable storage medium. The method is simple and convenient, and the encrypted character string used for protecting the original character string is generated without increasing the memory difficulty of the user, thereby improving the breaking difficultyof the character string.

Description

technical field [0001] The invention relates to the field of data encryption, in particular to a character string encryption, a verification method, a device and a computer-readable storage medium. Background technique [0002] In the current website program, the user's password is encrypted by an irreversible encryption algorithm and stored in the website's database. An encryption algorithm that is too simple is easily cracked, and an encryption algorithm that is too complex will bring performance to the server of the website. burden. Therefore, in most of the current website programs, the MD5 (Message Digest Algorithm 5, fifth edition of the message digest algorithm) encryption algorithm is usually used to encrypt the key data of the website. The algorithm always has a unique corresponding ciphertext for different plaintexts, and the ciphertexts are not repeated. At the same time, the complexity of the algorithm is moderate, and it will not bring a performance burden to t...
