Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with accompanying drawing to the present invention
Technical scheme be clearly and completely described, it is clear that described embodiment is part of the embodiment of the present invention, rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belongs to the scope of protection of the invention.
Directly password is encrypted with digest algorithms such as md5 or sha1 for conventional encryption technique at present, and cipher mode has very
Risks, hacker can be reduced by way of previously generating plain/cipher text corresponding table in plain text, so as to cause user cipher to be let out
Dew, so that cryptographic security is relatively low, based on this, safe encryption method provided in an embodiment of the present invention and system, by more
Summary and AES again, improve cryptographic security.
For ease of understanding the present embodiment, the safe encryption method disclosed in the embodiment of the present invention is carried out first detailed
It is thin to introduce.
Embodiment one：
Fig. 1 is the safe encryption method flow chart that the embodiment of the present invention one provides.
Reference picture 1, safe encryption method, including：
Step S101, obtain decodement；
Step S102, make a summary processing and encryption are carried out to decodement according to preset rules, obtain cryptographic secret.
Preset rules are advance customized encryption flows, usually, directly carry out summary calculation in Crypted password from the background
Method is encrypted, and hacker still can be made a summary pre-establishing all passwords and its and reduction ciphertext is attempted by way of corresponding table；It is this
Cipher mode risk is still bigger.The embodiment of the present invention is performed at multiple summary processing and multi-enciphering according to preset rules
Reason, can resist the attack carried out in a manner of previously generating corresponding table, even if hacker is aware of AES, he still needs
Attacked by re-establishing this violence mode of corresponding table, intrusion scene is very high.
Further, as shown in Fig. 2 step S102 can take following steps to realize：
Step S201, advance Custom Encryption flow, the encryption flow include multiple summary processing and multi-enciphering
Processing；
Step S202, according to encryption flow executive summary processing or encryption.
After decodement is got, first have to create encrypted object, Custom Encryption when encrypted object is created
Flow, various AES plug-in units are at this moment stored as a set.Each plug-in unit can perform a kind of encryption.Perform encryption stream
Cheng Shi, plug-in unit is taken out according to execution sequence successively from set, data are encrypted.
Further, step S202 includes repeating following processing, until obtaining the cryptographic secret：
First summary processing or the first encryption are performed by the first digest algorithm or the first AES, obtain first
Result of making a summary or the first encrypted result；
The described first summary result or first encrypted result are held by the second digest algorithm or the second AES
The processing of the summary of row second or the second encryption.
Specifically, encryption flow can arbitrarily be set, and executive summary processing or encryption, that is, pluck step by step
Handle and do not fixed with the order of encryption, number of steps is not also fixed.
As shown in figure 3, multiple summary processing and multi-enciphering processing procedure are exemplified below：
Step 1：Obtain user cipher in plain text；
Step 2：Summary processing is carried out using digest algorithm 1；
Step 3：The summary result of previous step is encrypted using custom algorithm 1；
Step 4：Summary processing is carried out using digest algorithm 2；
Step 5：The summary result of previous step is encrypted using custom algorithm 2；
Step 6：Made a summary according to actual conditions using multiple steps and encryption；
Step 7：Summary processing is carried out using digest algorithm n；
Step 8：Obtain cryptographic secret to the end and be saved into database, operation terminates.
For example, getting a decodement A, first pass through digest algorithm 1 and handle, obtain data B.Data B is carried out again
Custom Encryption, such as XOR, data C is obtained, digest algorithm 2 is carried out to data C again afterwards, the like, it is pre- until having performed
All summary processing steps and encryption processing step first set, obtain cryptographic secret to the end.
It should be noted that above-mentioned processing procedure is example, specific encryption flow can optionally carry out it is self-defined, i.e.,
The order of digest algorithm and AES is unfixed, performs number nor fixed.In addition, digest algorithm can also replace
It is changed to symmetric encipherment algorithm.
Further, the first digest algorithm and the second digest algorithm include CRC8 checking algorithms, CRC16 checking algorithms,
CRC32 checking algorithms, MD5 (Message Digest Algorithm, Message Digest Algorithm 5), MD4, MD2, SHA 1
(Secure Hash Algorithm, Secure Hash Algorithm), SHA 256, SHA384 and SHA512.
Wherein, CRC (Cyclic Redundancy Check, CRC) series include CRC8 checking algorithms,
CRC16 checking algorithms and CRC32 checking algorithms；MD4, MD2 represent Message Digest 5 fourth edition and the second edition respectively；SHA1 is
20 bytes (160), SHA256 are 32 bytes (256), SHA384 is 48 bytes (384), SHA512 is 64 bytes (512
Position).It should be noted that digest algorithm is not limited to these.
Further, in addition to：Cryptographic secret is preserved.
The embodiments of the invention provide safe encryption method and system, including：Obtain decodement；According to preset rules pair
The decodement carries out make a summary processing and encryption, obtains cryptographic secret.By it is self-defined it is multiple summary processing and
Encryption process, improve cryptographic security.
