Decoding, searching loop, the string one_to_one corresponding in the content that will encrypt and dynamic secret key, it is decrypted；Change into solving ciphertext data
The result that decimal number XOR obtains adds the computing of inverse rule, furthermore comparison ASCII character synopsis obtains corresponding character,
Obtain last solution ciphertext data.
Further, described cryptographic operation is further: definition secret key string $ key, the date format on the same day of splicing timestamp
And random number obtains dynamic secret key, dynamic key key=$ key.time (' m '-' d ') .rand (111,999)；Dynamic key
Key is stored in a time configuration file config.php as value, and key form is the date on the same day；Circulation carries out decimal scale to information
XOR and other operational rules, $ Sum=(ord ($ data{ $ i}) ^ord ($ char{ $ i}))+299；To encrypted result
Change into ASCII information chr ($ sum) of correspondence；Finally to the convenient transmission of operation result base64 coding obtained: Base64_
encode(chr($sum))。
Further, described decryption oprerations is further: obtain time configuration file config.php information, inquires about the same day
Value under date；Obtain dynamic secret key key, the content of encryption is carried out base64 position decoding $ data=Base64_encode ($
data)；Circulation carries out reverse operation $ Sum=(ord (the $ data of decimal scale XOR and other rule-based algorithm to information
{$i}-299)^ord($char{$i}))；Encrypted result changes into ASCII information chr (sum) of correspondence, is finally deciphered number
According to.
Present invention have the advantage that the arithmetic logic of 1. encryptions and deciphering is mutually symmetry, convenient amendment encryption and deciphering
Logic rule.If after 2. system interface rule is known by external staff, can be by amendment encryption logic rule and secret key
Mode, stops data to be stolen fast and effectively.3. code architecture, is not take up resource.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet that the present invention encrypts.
Fig. 2 is the schematic flow sheet that the present invention deciphers.
Detailed description of the invention
Referring to shown in Fig. 1 and Fig. 2, the method for a kind of data transmission encryption and decryption of the present invention, described method is in code
Define a secret key string, centered by this secret key string, data are encrypted, decryption oprerations；
Described cryptographic operation: secret key string, and character string to be encrypted carries out carry digit coding, is then transported by logic
Calculate, finally carry out base64 coding and obtain the character string of encryption；
Described decryption oprerations: secret key string, and character string to be deciphered carries out carry digit coding, is then transported by logic
Calculate, finally carry out base64 decoding and obtain the data of deciphering.
Wherein, described cryptographic operation particularly as follows:
First definition secret key string, splicing timestamp the same day date format and random number obtain dynamic secret key, so make number
Result after encrypting according to every day is the most different, increases disabled user and deciphers difficulty；One time configuration file is set again；Secondly circulation
Traversal, the string one_to_one corresponding in the content that will encrypt and dynamic secret key, it is encrypted, encryption data is changed into decimal number different
Or the result that computing obtains adds operational rule；Furthermore comparison ASCII character synopsis obtains corresponding character, to final result
Carry out base_64 coding and obtain the character string of encryption.
Described decryption oprerations particularly as follows:
First obtain the content of described time configuration file, inquire about the dynamic secret key on the same day, secondly to adding confidential information base64
