Description
Technical field
The present invention relates to encipher-decipher methods, and in particular to the encipher-decipher method based on Chinese Hash.
Background technique
With the application of various information systems, people have the text of many privacies or password to need to be recorded in a safety
Memory space, maintaining design to realize one can will be popular in the method for secure storage privacy of user.In addition, people are for close
The memory of code obviously is easier to be remembered using Chinese than letter and number mixing.However, existing encryption and decryption technique, one
As only allow user to carry out combination pin using letter, number and some additional characters, be not easy to user and remember.
Summary of the invention
It is of the existing technology in order to solve the problems, such as, guarantee that the safety of private data, the present invention propose a kind of based on Chinese
The encipher-decipher method of Hash guarantees the secure storage of privacy of user data using symmetric encryption method, and Chinese can be used in user
Pin design, convenient for memory.The present invention is realized using following technical scheme: the encipher-decipher method based on Chinese Hash, including
Ciphering process and decrypting process, wherein ciphering process include:
S11, the data for reading key and being encrypted；Whether check key is correct, correctly thens follow the steps S12；
S12, from memory application buffer area, buffer length and suffix are set；
S13, selection hash function handle data, obtain the corresponding position in ciphertext of each plaintext character；
S14, segmentation in plain text, apply for buffer area；
S15, the nonce that data obtain after hash function is handled is stored in buffer area；
S16, the buffer location of blank is filled up；
S17, character encryption is carried out to each character in buffer area, obtains final ciphertext；
Decrypting process includes:
S21, key and ciphertext are read, the ciphertext of input is handled；Whether check key is correct, correctly then executes step
Rapid S22；
S22, setting buffer size and buffer area suffix；
S23, selection hash function, divide ciphertext；
S24, application buffer area, determine ciphertext in buffer location using hash function；
S25, each character in buffer area is decrypted, intercepts suffix；
S26, the character of buffer area is utilized hash function composition plaintext.
Preferably, the hash function are as follows: unitary n times equation method, leaving remainder method, generating random number method or key row
Sequence method.
Preferably, the symbol of encryption described in step S17 is plus-minus or exclusive or.
Preferably, the key is Chinese key.
Compared with prior art, the present invention has the advantages that and advantage:
1, the present invention can input key and important text data and add as the distinctive mnemonic combinations information of user
It is close, it inputs ciphertext and key and is decrypted, in the case where user key is not revealed, data after user encryption can be completely secured
Safety, and any significant plaintext cannot be obtained using ciphertext under the premise of no key, effective protection user data
Safety.
2, the present invention is based on the realization of Hash thinking, enciphering rate is fast.In addition, based on encryption method of the invention, Ke Yishe
Multiple encipherors are counted out, a possibility that being cracked using public encryption method there are key is avoided.
3, Chinese characters encryption can be used in the present invention, and the characteristic of Chinese is made full use of to ensure its safety.For example, user can
To use Chinese to design oneself exclusive encryption key.If forgetting key, there is no other methods other than attempting encryption key method
Available data content can be effectively protected the privacy of user.
Detailed description of the invention
Fig. 1 is encryption flow of the invention；
Fig. 2 is decryption process of the invention.
Specific embodiment
In order to clearly describe the present invention, below in conjunction with specific embodiment and attached drawing, to technical solution of the present invention
Clear, complete description is carried out, embodiments of the present invention are not limited thereto.
Embodiment
Encipher-decipher method of the invention is encrypted using hash function, and Chinese can be used in key.Ciphering process such as Fig. 1
It is shown, comprising the following steps:
S11, first the data of input are handled: input user setting, the data for reading key and being encrypted；It verifies close
Whether key (also referred to as password) is correct, correctly thens follow the steps S12；
S12, from memory application buffer area, buffer length and suffix are set；
S13, selection hash function handle data, obtain the corresponding position in ciphertext of each plaintext character；Institute
Stating hash function can choose: unitary n times equation method, leaving remainder method, generating random number method or key ranking method.
S14, segmentation in plain text, apply for buffer area；
S15, the nonce that data obtain after hash function is handled is stored in buffer area；
S16, the buffer location of blank is filled up；
S17, character encryption is carried out to each character in buffer area, obtains final ciphertext.Encrypted symbols can be used exclusive or,
Plus-minus.
Decrypting process such as Fig. 2, comprising the following steps:
S21, key and ciphertext are read, the ciphertext of input is handled；Whether check key is correct, correctly then executes step
Rapid S22；
S22, setting buffer size and buffer area suffix；
S23, selection hash function, divide ciphertext；
S24, application buffer area, determine ciphertext in buffer location using hash function；
