PHP AES encryption corresponds to Java sha1prng mode encryption

When doing docking, the service provider AES encryption through the SHA1PRNG algorithm (as long as the password, each generation of the array is the same, so can be used to do encryption and decryption key) for another time encryption, engaged for several hours, directly see the corresponding code bar, you can refer to, Java-only encrypted source
