Now we know that one of the biggest problems with symmetric encryption is how to transfer the key securely and not find a good solution in a symmetric encryption system. 1976, American scholar dime and Henman in order to solve the problem of information public transmission and key management, a new key exchange protocol is proposed, which allows both parties to exchange information on unsecured media and se

PHP's encryption and decryption string function, php's encryption and decryption string. The PHP encryption and decryption string function code is as follows: **************************************** * ***** PHP's string encryption and decryption function, php encryption and
In the previous section, we discussed that symmetric encryption can solve the problem of communication confidentiality, but it cannot guarantee the integrity of the information.Then we introduce an algorithm-one-way encryption. One-way encryption, like human fingerprints, is unique.A to B when the information will be appended to the end of the one-way
In the previous section, symmetric encryption (resolution:Confidentiality of), one-way encryption (resolves:completeness), key exchange (resolution:completeness)。 But is it always possible to be disruptive by e, is there a way to resolve the identity of the other way?This time the public key encryption algorithm comes out. It is well known that public key cryptog

For most password encryption, we can use md5, sha1, and other methods. This can effectively prevent data leaks, but these methods only apply to data encryption that does not require restoration. For the information to be restored, a reversible encryption and decryption algorithm is required. the following set of PHP functions implement this
How to crack md5 encryption and how to crack md5 EncryptionWe know that md5 encryption is irreversible, but it is easy to crack md5 encryption.There are also many online attacks. Since it is irreversible, how did the online cracking come from?The reason is simple, that is, brute force cracking.For example, we calculate the md5 of the combination of all characters on the keyboard, and store the encrypted str
