PHP interface Data encryption, decryption, authentication signature

The code is very simple, here is no more nonsense, directly to the code

The

code is 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


$crypttext = ' v66ykulhfld2jelhm/j9qik2edr1jhdzic/k/oesu2gbtx2usxyvf4jgvzvoihrre8fsfkmllmjsmijo5fdrs/ fd20byfii4jw3bo3bzshxmz6aes2dwwg4sk9mnojfoc0ismov311x5/jlguoqxkdy4f5hhpye9d/xgb0g2xe/ hngssy2cpqcvqtblbmixwscknhseg92lovloz8ulwkqg5o7x+qb7p/emii/ wafaxbjxdxvzx7lmgcogon6wlhkjlgxorp6bixog6lgc6ux7bat3i9+0lujngxiq/sdsl23hsr3youpv5c5a813nrhx4hjyd/hbt1uviuml+ etmjwwcpsfs2cvxiur0ce57jazvyxjk13shk3iszhlppsm/jcdcrdy0co/d5uigjadzxdsq56xsju+tlvna1j6yq2tdifyk/ x6k911a5wxlkyxztd1nq+btyn3gv/wffrzvtgwqbrh06ihs2cwvna0s9ev/ypmhnajjmrx4trnr9nxq9xazaw4lgrg87u5qdv+ nqjj1thk0xhfc69n9g2+dsagyes9tk6u0zq72hjzqzhbcdh1ukw0plyihjdxpgppowgp8/qvvu2jultekunvgaaec3n+ Gozfqjscdi1s6t2mtnjwywnofrbhvezfd/revgpastozdqa5nqr1b+muf70r6uw6mwlj7ct9tz3jq+ca ';


$aeskey = Base64_decode (' qze60qzfxuirub2ey4+7+q== ');


//aes declassified, 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 ' <hr/> ';


//aes Encrypted plaintext


//echo $aes->encrypt ($plaintext);

//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 ());

//Using RSA private key to generate signature


//$rsa->loadkey ($privatekey);


//$signature = $rsa->sign ($plaintext);


//Using RSA Public key authentication Signature


Echo $plaintext;


$rsa->loadkey (Base64_decode ($publickey));


echo $rsa->verify ($plaintext, Base64_decode ($signature))? ' Verified ': ' unverified ';


echo ' <hr/> ';


//Generate RSA public key, private key


//var_dump ($rsa->createkey ());


Extract ($rsa->createkey ());


//Using RSA private key to encrypt data


$rsa->loadkey ($privatekey);


$ciphertext = $rsa->encrypt ($plaintext);


//Using RSA public key to decrypt data


$rsa->loadkey ($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.
