In the existing method for resetting the password of the block chain wallet, the data of the wallet is forcibly removed from the wallet client side by means of software unloading, software data clearing and the like, and then the wallet is re-imported by the private key import or mnemonic import function of the block chain client side, and a new wallet password can be set during import. The method is cumbersome to operate, and since the blockchain client often includes a plurality of blockchain wallets, when the password of one of the blockchain wallets is reset, the existing method may cause data of other blockchain wallets to be damaged or lost.
In view of this, the present embodiment provides a solution for resetting a block chain wallet with a password to be reset in a targeted manner, and the solution provided in the present embodiment is described in detail below.

The Processor 130 may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; but may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware components. The various methods, steps, and logic blocks disclosed in the embodiments of the present application may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
Referring to fig. 2, the present embodiment provides a flowchart of steps of a password resetting method applied to the electronic device 100 shown in fig. 1, and the steps of the method will be described in detail below.
In step S100, a target blockchain wallet for a password to be reset is determined.
Optionally, the blockchain wallet client is used to manage software for blockchain wallets, through which wallets can be imported and deleted, through which assets in the blockchain wallet can be transferred, or collected, transaction records viewed, and the like. Multiple blockchain wallets, such as BTC wallets, ETH wallets, EOS wallets or other blockchain wallets, can be managed by our wallet client. The user selects a target blockchain wallet from the blockchain client for the password to be reset.
Step S200, a password resetting request is obtained, the password resetting request comprises a resetting password and authentication information, the authentication information comprises a private key or mnemonic words, and a first public key is generated according to the authentication information.
Optionally, an interface is provided through which the user enters a mnemonic or private key and enters a reset password. The electronic device 100 generates a first public key according to the mnemonic word or the private key.
Step S300, comparing the first public key with the original second public key of the target block chaining wallet.
In step S400, if the first public key is the same as the second public key, the reset password is used as a new password of the target block chaining wallet.
Optionally, the electronic device 100 compares the first public key and the second public key. And if the first public key is the same as the second public key, taking the reset password as a new password of the target block chaining wallet. Further, the electronic device 100 encrypts the private key according to the reset password to obtain a new KeyStore file, and replaces the original KeyStore file of the target block chain wallet with the new KeyStore file. It should be noted that, before replacing the original KeyStore file of the target block chain wallet, the electronic device 100 performs backup processing on the original KeyStore file to obtain a KeyStore backup file.
To prevent an unexpected situation from occurring when a new KeyStore file is generated, resulting in damage or other data errors in the newly generated KeyStore file. Referring to FIG. 3, a flowchart illustrating steps for validating a KeyStore file is shown.
In step S5001, the KeyStore backup file is deleted after the user enters the target blockchain wallet with the new password for the first time.
Optionally, after the user has reset the password, the target blockchain wallet is entered with a new password. If the user can successfully enter the target blockchain wallet with a new password, the electronic device 100 deletes the KeyStore backup file.
Step S5002, the user enters the target blockchain wallet with the new password for the first time, and if the number of times of password input by the user exceeds a preset threshold, the new KeyStore file is replaced with the KeyStore backup file.
Alternatively, if the number of times the user enters a new password exceeds a preset threshold, the target blockchain wallet cannot be entered. For example, if the user enters a new password more than 5 times and cannot enter the target blockchain wallet, it indicates that the newly generated KeyStore file is corrupted or has other data errors when the new KeyStore file is generated. The electronic device 100 replaces the KeyStore backup file with the newly generated KeyStore file and prompts the user to reset the password again. Through the mode, file damage or other data errors are avoided when the generated KeyStore file is generated, so that the encrypted private key is not the original private key of the blockchain wallet. And finally, forcibly removing the data of the wallet from the wallet client only by means of software unloading, software data clearing and the like, and re-importing the data into the wallet through a private key import or mnemonic import function of the blockchain client, wherein a new wallet password can be set during import.
Optionally, in order to prevent an illegal user from brute force cracking, if the number of times of the public key or the mnemonic word input by the user exceeds a preset threshold, the user is prohibited from inputting the public key or the mnemonic word again within a preset time. For example, if the user inputs a mnemonic word or the private key cannot be successfully matched with the original public key of the target block chain wallet after the time exceeds 10 hours, the user is allowed to perform the operation of resetting the password again after delaying for 1 hour.
