The code is very simple, here is no more nonsense, directly to the code
Copy Code code as follows:
<?php
Header (' Content-type:text/xml; Charset=utf-8 ');
Include_once (DirName (dirname (__file__)). Directory_separator. ' Phpsec '. Directory_separator. ' Math '. Directory_separator. ' biginteger.php ');
Include_once (DirName (dirname (__file__)). Directory_separator. ' Phpsec '. Directory_separator. ' Crypt '. Directory_separator. ' aes.php ');
Include_once (DirName (dirname (__file__)). Directory_separator. ' Phpsec '. Directory_separator. ' Crypt '. Directory_separator. ' rsa.php ');
Ciphertext

AES decryption, using ECB mode
$aes = new Crypt_aes (CRYPT_MODE_ECB);
Set AES Key
$aes->setkey ($aeskey);
Decrypt AES Redaction
$plaintext = $aes->decrypt (Base64_decode ($crypttext));
Echo $plaintext;
echo ' AES Encrypted plaintext
echo $aes->encrypt ($plaintext);
RSA Public Key

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 RSA public key, private key
Extract ($rsa->createkey ());
To generate a signature using the RSA private key
$rsa->loadkey ($privatekey);
$signature = $rsa->sign ($plaintext);
Verifying signatures with RSA public key
Echo $plaintext;
$rsa->loadkey (Base64_decode ($publickey));
echo $rsa->verify ($plaintext, Base64_decode ($signature))? ' Verified ': ' unverified ';
echo ' Generate RSA public key, private key
Var_dump ($rsa->createkey ());
Extract ($rsa->createkey ());
Encrypting data using the RSA private key
$rsa->loadkey ($privatekey);
$ciphertext = $rsa->encrypt ($plaintext);
Decrypting data using the RSA public key
$rsa->loadkey ($publickey);
echo $rsa->decrypt ($ciphertext);
The above is the entire content described in this article, I hope this code can give you learn PHP encryption and decryption can bring some help.
