Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, when people use internet applications, users are generally required to be registered for each internet application, safe and reliable passwords are required to be set, different internet applications are required, the set passwords are generally different, the passwords are required to be modified periodically for ensuring the safety, the password safety of some financial software applications is more important, and once the passwords are leaked or maliciously cracked, the personal economic property loss is caused; the secure management of these passwords is a difficult and difficult task for individual users.
Based on this, embodiments of the present invention provide a password generation method, apparatus, and device, and the technology may be applied to management of multiple passwords.
In order to facilitate understanding of the embodiment, a password generation method disclosed in the embodiment of the present invention is first described in detail; as shown in fig. 1, the method comprises the steps of:
step S102, generating at least one sub-private key corresponding to a specified path according to a pre-generated main private key and the specified path in a preset password path rule; the password path rule is used for determining a path for generating the password.
The master private key can generate different sub private keys through an internal derivation algorithm, and can control the generated sub private keys, and the generated sub private keys are also fixed as long as the derivation algorithm is not changed; the password path rule is used for determining a path for generating the password, for example, the path 1 is WeChat, the path 2 is microblog, and the path 3 is Paibao; the specified path can be WeChat, microblog or pay money and the like; during actual implementation, at least one sub-private key corresponding to a specified path can be generated according to the pre-generated main private key and the specified path in the preset password path rule; for example, for the WeChat, a plurality of paths of the WeChat, such as the WeChat path 1, the WeChat path 2, etc., may be provided, and the WeChat private key 1 corresponding to the WeChat path 1, the WeChat private key 2 corresponding to the WeChat path 2, etc., may be generated based on the pre-generated master private key.
Step S104, generating a sub-password corresponding to the sub-private key according to the sub-private key and a specified password format in a preset password generation rule; wherein the password generation rule is used to determine a password format.
The password format can comprise various combination formats such as pure numeric passwords, numeric-letter combination passwords and the like; the sub-password can be understood as a password of a path corresponding to the sub-private key generated according to the sub-private key; for example, if the wechat path 1 corresponds to the wechat son private key 1, and the wechat path 2 corresponds to the wechat son private key 2, the wechat son password 1 generated according to the wechat son private key 1 and the specified password format is the sub password corresponding to the wechat path 1, and can also be understood as the first password generated by the wechat; the WeChat sub-password 2 generated according to the WeChat sub-private key 2 and the specified password format is a sub-password corresponding to the WeChat path 2 and can also be understood as a second password generated by WeChat, and by analogy, a plurality of sub-passwords can be generated for WeChat, and the passwords of the WeChat paths are different; as an example, when a user needs a WeChat password, the WeChat sub-password can be automatically displayed only by selecting a path of the WeChat and a rule for generating the sub-password; only the WeChat can be selected, so that all the sub-passwords corresponding to the WeChat can be displayed.
In practical implementation, the sub-private key can be used for generating the sub-password in the specified password format through the customized password generation algorithm, and in general, the sub-password generated according to the specified sub-private key is also fixed and unchanged as long as the customized password generation algorithm is unchanged.
According to the password generation method provided by the embodiment of the invention, at least one sub-private key corresponding to a preset path is generated according to the preset main private key and the preset path in the password path rule; and generating a sub-password corresponding to the sub-private key according to the sub-private key and a specified password format in a preset password generation rule. In the method, the sub-private keys corresponding to different paths in the preset password path rule can be generated through the pre-generated main private key, so that the sub-passwords are generated, and at least one sub-password can be generated for the same appointed path, so that the password of the appointed path is convenient for a user to update, and the convenience for the user to manage the password is improved.
The embodiment of the invention also provides another password generation method, which is realized on the basis of the method of the embodiment; as shown in fig. 2, the method comprises the steps of:
step S202, generating at least one sub-private key corresponding to a specified path according to a pre-generated main private key and the specified path in a preset password path rule; the password path rule is used for determining a path for generating the password.
In practical implementation, the pre-generated master private key is generated by the following method:
step 20, when a login instruction sent by a user for the first time is received, generating a random seed corresponding to the user; wherein the random seed comprises a randomly generated string.
When a user uses a device or equipment capable of implementing the password generation method in this embodiment for the first time, the device or equipment generates a unique random seed for the user and stores the random seed, where the random seed is usually a string of longer random numbers; in practical implementation, the step may be implemented based on a scrambler or the like, or may be implemented in other forms, and the implementation manner may be diversified.
Step 21, generating a master private key corresponding to the random seed.
In actual implementation, a unique main private key capable of managing the sub-passwords can be generated for the random seed through an internal algorithm; that is, the random seed and the master private key are in one-to-one correspondence, and as long as the random seed is determined, the master private key generated by the random seed is generally uniquely determined.
Step S204, generating a sub-password corresponding to the sub-private key according to the sub-private key and a specified password format in a preset password generation rule; wherein the password generation rule is used to determine a password format.
In step S206, a mnemonic word corresponding to the random seed is generated.
Considering that the random seed is usually a character string composed of a string of longer random numbers, which is inconvenient for the user to use, and for the user to record and use, the random seed can be converted into a plurality of common English words or Chinese characters and the like through a preset algorithm, namely, the mnemonic words are mnemonic words, the mnemonic words and the random seed are in one-to-one correspondence, and the generated mnemonic words are usually determined uniquely as long as the random seed is determined; the specific implementation manner may refer to a hierarchical deterministic cryptography, where hierarchical deterministic (HD for short) is proposed in BIP32 (bitcoil improved products 32, a file that proposes new functions or improvements of Bitcoin) of a Bitcoin blockchain item, as shown in the flowchart of the hierarchical deterministic method shown in fig. 3, and the proposed scheme indicates that a main private key is generated by a random seed, and then a huge number of sub private keys are derived; however, since the random seed is a long string of random numbers which is inconvenient to record, the BIP39 proposal converts the random seed into a string of mnemonics, so that the random seed is convenient to record and store; the subsequent proposals BIP43 and BIP44 define derived paths, and form more convenient use specifications.
In practical implementation, a user can manage all the sub-passwords of the user only by recording the unique mnemonic words of the user, and can update the used sub-passwords periodically without worrying about forgetting the sub-passwords. The user properly records and stores the generated mnemonic words, and the mnemonic words can be recorded by paper, and can also be stored in a device or equipment for realizing the password generation method according to a specific implementation mode; the user may also import the existing mnemonic words into the device or apparatus for use, for example, when the user used the device or apparatus before, generated the random seed and mnemonic words, possibly lost the device or apparatus, or wants to replace a new device or apparatus, the user may directly import the mnemonic words that have been remembered originally into the new device or apparatus, continue to use the originally generated sub-password, etc.; the passwords corresponding to the original mnemonic word and the current mnemonic word are different, because the random seed is changed, as long as the random seed is changed, the finally generated sub-passwords are usually completely different. As can be seen from the above, if there are a plurality of the above devices or apparatuses, one user may have a plurality of random seeds.
According to the password generation method, after the random seed corresponding to the user is generated, the mnemonic word corresponding to the random seed is generated according to the random seed, in the method, the sub-private keys corresponding to different paths in the preset password path rule can be generated through the pre-generated main private key, and then the sub-passwords are generated, and at least one sub-password can be generated for the same appointed path, so that the password of the appointed path is convenient for the user to update, and the convenience of the user in managing the password is improved.
The embodiment of the invention also provides another password generation method, which is realized on the basis of the method of the embodiment; as shown in fig. 4, the method includes the steps of:
step S402, generating at least one sub-private key corresponding to a specified path according to the preset main private key and the specified path in the preset password path rule; the password path rule is used for determining a path for generating the password.
Step S404, generating a sub-password corresponding to the sub-private key according to the sub-private key and a specified password format in a preset password generation rule; wherein the password generation rule is used to determine a password format.
In step S406, a password index number corresponding to the sub-password is generated.
Taking the WeChat as an example, as can be seen from the above embodiments, a plurality of sub-passwords may be generated for the WeChat; in order to facilitate the record management, the plurality of sub-passwords may be respectively numbered, for example, the numbers are respectively 0, 1, and the like, and the number is the above-mentioned password index number.
When a user needs to update the password, a new password index label can be selected from the existing password index labels, or a new sub-password is generated according to the password path rule and the password generation rule; taking the WeChat as an example, for example, only one WeChat path 1 and the corresponding sub-password 1 are currently provided, in order to update the WeChat password, the WeChat sub-private key 2 corresponding to the WeChat path 2 may be generated according to the password path rule, and then the WeChat sub-password 2 corresponding to the WeChat sub-private key 2 may be generated according to the password generation rule, and when the WeChat password is used, the generated WeChat sub-password 2 may be selected, thereby implementing the update of the WeChat password.
In step S408, a password generation rule flag corresponding to the password format is generated.
In actual implementation, when the sub-password is generated, a proper password format can be selected according to requirements; the password format typically includes numbers, letters, or special characters, as well as the password length; for example, pure numeric passwords of different lengths, combinations of numeric letters, combinations of upper and lower case of numeric letters, combinations of special characters of numeric letters, and the like; in order to facilitate recording and managing different combination modes, different flags are usually configured for different combination modes, the configured flags are the above-mentioned password generation rule flags, and the format of the password to be generated can be determined by the password generation rule flags.
In practical implementation, the path in the above password generation rule at least includes: at least one of an application software mark, a user name of a user in the application software, the password generation rule mark and the password index number; of course, other information that can determine the path for generating the password may be included.
According to the password generation method, the password index number corresponding to the sub-password is generated, the password generation rule mark corresponding to the password format is generated, the generated sub-password and the password formats in different combination modes are convenient to record and manage, the sub-passwords corresponding to different paths in the preset password path rule can be generated through the pre-generated main private key, the sub-passwords are further generated, and at least one sub-password can be generated for the same appointed path, so that the password of the appointed path is convenient to update for a user, and the convenience of the user in password management is improved.
To further understand the above embodiment, another flowchart of the password generation method is provided below, as shown in fig. 5, fig. 5 includes a random seed, a main private key, a wechat sub private key 1 and a corresponding wechat sub password 1, a microblog sub private key 2 and a corresponding microblog sub password 2, a pay-for-treasure private key N and a corresponding pay-for-treasure sub password N; the password path rule comprises WeChat, microblog and Payment treasures; the random seed generates a unique main private key through an internal algorithm, the main private key generates a sub private key corresponding to an appointed path according to the appointed path in the password path rule, namely a WeChat sub private key 1 is generated according to the WeChat path, a microblog sub private key 2 is generated according to the microblog path, and a Payment baby sub private key N is generated according to the Payment baby path; and generating a sub-password corresponding to the sub-private key according to the sub-private key and a specified password format in a preset password generation rule, namely generating a micro-letter sub-password 1 corresponding to the micro-letter sub-private key 1, a micro-blog sub-password 2 corresponding to the micro-blog sub-private key 2 and a Payment Baozi sub-password N corresponding to the Payment Bao sub-private key N according to the password format specified by the user.
