Abstract
The invention belongs to the field of information safety, and provides a method and a system for encrypting, saving and verifying account data. Firstly, information of a to-be-added user is encrypted through a random encryption character string; secondly, when a registered user logs in, a cipher saving character string is generated according to input ciphers, the cipher saving character string is compared with the saved cipher saving character string, and verification is obtained; and at the same time, every time login and verification occur, the random encryption character string and the cipher saving character strings are refreshed dynamically, so that the problem that an encryption method and system in the prior art do not support functions of refreshing character strings and character string saving ciphers dynamically is effectively solved, the safety and the reliability of the ciphers are greatly improved, and the account data can be protected well.
Description
Technical field
The invention belongs to information security field, relate in particular to a kind of method and system of preserving with checking that Account Profile is encrypted.
Background technology
The outpost of the tax office, first road of system be exactly the account number that the user lands usefulness, and the encrypting storing of the password that relates in the account number is exactly vital;
Present technology is common to be to adopt the conventional encryption of md5; increased system's fixed-encryption character string; but there is not the accidental enciphering character string; do not support dynamic refresh random string and dynamic refresh character string storage password; in case dragged the storehouse by the hacker; supporting employing Brute Force tends to be cracked again, and the safety of user's Account Profile can not get protecting effectively.
Summary of the invention
The invention provides a kind of method and system of preserving with checking that Account Profile is encrypted; be intended to solve the encryption method of the password that prior art provides; often adopt the conventional encryption of md5; do not support dynamic refresh random string and dynamic refresh character string storage password; in case dragged the storehouse by the hacker; supporting employing Brute Force more easily is cracked again, the problem that the safety of user's Account Profile can not get protecting effectively.
The object of the present invention is to provide a kind of Account Profile is encrypted to preserve and the method for verifying, this method may further comprise the steps:
