The code is very simple, so there is not much nonsense here, and the code is provided directly.

The Code is as follows:

<? Php
// Header ('content-Type: text/xml; charset = UTF-8 ');
Include_once (dirname (_ FILE _). DIRECTORY_SEPARATOR. 'phpsec '. DIRECTORY_SEPARATOR. 'Math'. DIRECTORY_SEPARATOR. 'biginteger. php ');
Include_once (dirname (_ FILE _). DIRECTORY_SEPARATOR. 'phpsec '. DIRECTORY_SEPARATOR. 'crypt'. DIRECTORY_SEPARATOR. 'aes. php ');
Include_once (dirname (_ FILE _). DIRECTORY_SEPARATOR. 'phpsec '. DIRECTORY_SEPARATOR. 'crypt'. DIRECTORY_SEPARATOR. 'rsa. php ');
// Ciphertext
$ Crypttext = 'encrypt/decrypt/k/encrypt/decrypt/xGb0g2XE/encrypt + qB7P/EMII/encrypt + 0 lujNgxIq/encrypt/hBT1UvIUml + encrypt/JcDCrdy0Co/decrypt + decrypt /release + btyn1_v/release + nQjj1THk0XHFc69N9g2 + release/QVVU2julTeKunvgAAEc3n + release/revgpasTOzDQa5NqR1B + release + CA ';
$ Aeskey = base64_decode ('qze60qzfxuirub2ey4 + 7 + Q = ');
// AES decryption, in ECB Mode
$ Aes = new Crypt_AES (CRYPT_MODE_ECB );
// Set the AES key
$ Aes-> setKey ($ aeskey );
// Decrypt the AES ciphertext
$ Plaintext = $ aes-> decrypt (base64_decode ($ crypttext ));
Echo $ plaintext;
Echo'

';
// AES encrypted plaintext
// Echo $ aes-> encrypt ($ plaintext );
// Rsa public key
$ Publickey = 'prop + rDknXLqMT + DXeQAqGo4hBmcbej1aoMzn6hIJHk3/large/A0Vfb0 + xm8mnf46ddhhrrycerbsbyrcwidaqab ';
// Echo base64_decode ($ publickey );
// Rsa Signature
$ Signature = 'xhin4uufqrkdehkbd/signature + Q0eqwsoAdywsVQDEceG5stas1CkPtrznAIW2eBGXCWspOj + aumEAcPyYDxLhDN646Krzw = ';
// Echo base64_decode ($ signature );
$ Rsa = new Crypt_RSA ();
// Set the RSA Signature mode CRYPT_RSA_SIGNATURE_PSS or CRYPT_RSA_SIGNATURE_PKCS1
$ Rsa-> setSignatureMode (CRYPT_RSA_SIGNATURE_PKCS1 );
// Var_dump ($ rsa-> createKey ());
// Generate the RSA public key and Private Key
// Extract ($ rsa-> createKey ());
// Use the RSA private key to generate a signature
// $ Rsa-> loadKey ($ privatekey );
// $ Signature = $ rsa-> sign ($ plaintext );
// Use the RSA public key to verify the signature
Echo $ plaintext;
$ Rsa-> loadKey (base64_decode ($ publickey ));
Echo $ rsa-> verify ($ plaintext, base64_decode ($ signature ))? 'Verified ': 'unverified ';
Echo' ';
// Generate the RSA public key and Private Key
// Var_dump ($ rsa-> createKey ());
Extract ($ rsa-> createKey ());
// Use the RSA private key to encrypt data
$ Rsa-> loadKey ($ privatekey );
$ Ciphertext = $ rsa-> encrypt ($ plaintext );
// Use the RSA public key to decrypt data
$ Rsa-> loadKey ($ publickey );
Echo $ rsa-> decrypt ($ ciphertext );

The above is all the content described in this article. I hope this code can help you learn about php encryption and decryption.
