encrypt string

Php custom encryption solution implementation code. The Mcrypt encryption library in PHP requires additional settings. many people directly use the md5 () function for encryption. this method is indeed safe, but because md5 is irreversible

Two classic PHP encryption and decryption functions. In projects, we sometimes need to use PHP to encrypt specific information, that is, to generate an encrypted string through the encryption algorithm, this encrypted string can be used in projects

A piece of php encryption and decryption code $ Key = "This is supposed to be a secret key !!! "; Function keyED ($ txt, $ encrypt_key) { $ Encrypt_key = md5 ($ encrypt_key ); $ Ctr = 0; $ Tmp = ""; For ($ I = 0; $ I { If ($ ctr = strlen ($

And the Java side of the docking, I use PHP decryption, key is 36 bytes, so there is no clue. I wonder if there's a generic way to convert these 36 bytes into 16 or 32 bytes? Thank you all first. Here is the code snippet for Java: public static
