Problems solved by technology

As a result, the existing MD5-based encrypted user information cannot be authenticated normally after migrating to Sun LDAP
Moreover, due to the large number of users and the wide area involved, it is difficult to modify the password through the user after direct import, and it is urgent to implement MD5 algorithm authentication

Embodiment 1

[0035] This embodiment discloses an MD5 encrypted authentication method based on LDAP (Lightweight Directory Access Protocol) applied in the system upgrade process, especially when upgrading the SSL VPN authentication based on F5 equipment, using the method based on this embodiment LDAP's MD5 encryption authentication method can migrate all user information from F5Fire Pass to Sun LDAP.

[0036] In order to solve the problem of migration and import of all user information, it is necessary to develop an algorithm separately to realize MD5 encryption and authentication according to the interface provided by Sun LDAP.

[0037] Such as figure 1 As shown, the LDAP-based MD5 encryption authentication method of the present embodiment includes:

[0038] Step S10, acquiring multiple user information;

[0039] Wherein, user information includes but not limited to user name and password and so on.

[0040] Typically, multiple user profiles already exist on the F5 device. The acquisit...

Embodiment 2

[0067] This embodiment discloses an MD5 encryption authentication method based on LDAP (Lightweight Directory Access Protocol), which is used for comparing and authenticating user information based on MD5 in Sun LDAP, thereby realizing authentication of user information.

[0068] Such as figure 1 As shown, the LDAP-based MD5 encryption authentication method of the present embodiment includes:

[0069] Step S10, obtain a user information:

[0070] Wherein, user information includes but not limited to user name and password and so on.

[0071] In this embodiment, acquisition of a user's information is usually directly input by the user through a display interface.

[0072] Step S20, encrypting the acquired user information based on the MD5 algorithm to obtain encrypted password information.

[0073] The processing procedure of step S20 is completely the same as that of step S20 in Embodiment 1, and will not be repeated here.

[0074] Step S30, judging the quantity of acquire...

Embodiment 3

[0101] This embodiment discloses a LDAP-based MD5 encryption authentication system, such as Figure 4 shown, including:

[0102] The acquiring unit 410 is configured to acquire one or more pieces of user information; wherein, the user information includes but not limited to user names and passwords and so on.

[0103] The encryption unit 420 is configured to perform encryption processing based on the MD5 algorithm on each acquired user information to obtain corresponding password information.

[0104] In this embodiment, the encryption unit 420 includes: an encryption subunit 421 , an encoding subunit 422 and an identification subunit 423 . in,

[0105] The encryption subunit 421 is configured to encrypt each user information acquired by the acquisition unit 410 based on the MD5 algorithm to obtain a corresponding encrypted character string;

[0106] The encoding subunit 422 is used to perform BASE64 encoding conversion on the encrypted character string to obtain the encode...

Abstract

The present invention provides an MD5 encryption authentication method and system based on a lightweight directory access protocol, comprising: acquiring one or more user information; performing encryption based on the MD5 algorithm on each acquired user information, and correspondingly obtaining encrypted password information ;Judging the number of user information obtained: when obtaining multiple user information, store the obtained user information and encrypted password information correspondingly; The obtained password information is compared for authentication. The present invention can not only migrate all user information from F5 Fire Pass to Sun LDAP, realize cross-product data migration, but also perform MD5-based comparative authentication on user information in Sun LDAP, which solves the problem that Sun LDAP cannot perform data based on MD5 authentication problem.

Description

technical field [0001] The present invention relates to the field of encryption authentication, in particular to an MD5 (Message-Digest Algorithm 5) encryption authentication method and system based on SUN LDAP (Lightweight Directory Access Protocol, Lightweight Directory Access Protocol). Background technique [0002] The VPN (Virtual Private Network, Virtual Private Network) technology built on the basis of the SSL (Security Socket Layer, Secure Socket Layer) protocol is a network communication technology for remote users to securely access the intranet of the enterprise. The SSL protocol ensures the confidentiality and integrity of data transmitted on the Internet by encrypting the entire session between computers; VPN is a point-to-point dedicated line established by an enterprise or other groups through private tunnel technology in public network resources , which can ensure the confidentiality of data and have certain access control functions. Combining the two forms "...
