What is private key cryptography technologyThe private key (symmetric key), also known as the symmetric key. The key encryption algorithm uses the same key for encryption and decryption. It has the advantage of very fast encryption and decryption, but it

Looks like just changed the code (the variable name into a garbled god horse ...)Base64, what's the encryption?Guess phpjm_ god horse horse is supposed to be a special key ...It's not really encrypted anyway, just wait for Daniel to have a more detailed introduction to verify my guess.

The problem that the file cannot run normally after modification is:
After the code is executed, the header string is detected with get_file_contents (_ FILE.
In addition, such code encryption has two huge performance problems:
Get_file_contents has at least one additional system

Symmetric cryptography refers to the same secret key that is used when encrypting and decrypting. Unlike symmetric encryption algorithms, asymmetric encryption algorithms require public and private keys. The public and private keys are a pair, and if the data is encrypted with the public key, only the corresponding pri

CPUs can be used for a wider range of integer operations while supporting larger memory. Specific as follows:
From an operation, a 32-bit processor can handle only 32 bits at a time, which is 4 bytes of data, while a 64-bit processor can handle 64-bit, or 8-byte data at a time.
From memory, the traditiona

Username=y2ltz5kxajpyzmq=psw=k2dpazwyaw==type=1
The username is the account, and the PSW is the password.

The ciphertext is like this: V53: eJwzcDJAASYWRhaGLsYGLqamTpZGji4GJuYGlpbGbm4mhhbmxi6OAPBkCik. the plaintext corresponds to the 11-digit mobile phone number. you can confirm this. Therefore, I would like to ask? The ciphertext is like this: V53: eJwzcDJAASYWRhaGLsYGLqamTpZGji4GJuYGlpbGbm4mhhbmxi6OAPBkCik =
