这篇文章主要介绍了使用openssl实现rsa非对称加密算法的示例,大家参考使用吧
代码如下:_keypath = $path; } /** * create the key pair,save the key to $this->_keypath */ public function createkey() { $r = openssl_pkey_new(); openssl_pkey_export($r, $privkey); file_put_contents($this->_keypath . directory_separator .

'pub.key', $pubkey); $this->_pubkey = openssl_pkey_get_public($pubkey); } /** * setup the private key */ public function setupprivkey() { if(is_resource($this->_privkey)){ return true; } $file = $this->_keypath . directory_separator . 'priv.key'; $prk = file_get_contents($file); $this->_privkey = openssl_pkey_get_private($prk); return true; } /** * setup the public key */ public function setuppubkey() { if(is_resource($this->_pubkey)){ return true; } $file = $this->_keypath . directory_separator . 'pub.key'; $puk = file_get_contents($file); $this->_pubkey = openssl_pkey_get_public($puk); return true; } /** * encrypt with the private key */ public function privencrypt($data) { if(!is_string($data)){ return null; } $this->setupprivkey(); $r = openssl_private_encrypt($data, $encrypted, $this->_privkey); if($r){ return base64_encode($encrypted); } return null; } /** * decrypt with the private key */ public function privdecrypt($encrypted) { if(!is_string($encrypted)){ return null; } $this->setupprivkey(); $encrypted = base64_decode($encrypted); $r = openssl_private_decrypt($encrypted, $decrypted, $this->_privkey); if($r){ return $decrypted; } return null; } /** * encrypt with public key */ public function pubencrypt($data) { if(!is_string($data)){ return null; } $this->setuppubkey(); $r = openssl_public_encrypt($data, $encrypted, $this->_pubkey); if($r){ return base64_encode($encrypted); } return null; } /** * decrypt with the public key */ public function pubdecrypt($crypted) { if(!is_string($crypted)){ return null; } $this->setuppubkey(); $crypted = base64_decode($crypted); $r = openssl_public_decrypt($crypted, $decrypted, $this->_pubkey); if($r){ return $decrypted; } return null; } public function __destruct() { @ fclose($this->_privkey); @ fclose($this->_pubkey); } } //以下是一个简单的测试demo,如果不需要请删除$rsa = new rsa('ssl-key'); //私钥加密,公钥解密echo 'source:我是老鳖
';$pre = $rsa->privencrypt('我是老鳖');echo 'private encrypted:
' . $pre . '
'; $pud = $rsa->pubdecrypt($pre);echo 'public decrypted:' . $pud . '
'; //公钥加密,私钥解密echo 'source:干it的
';$pue = $rsa->pubencrypt('干it的');echo 'public encrypt:
' . $pue . '
'; $prd = $rsa->privdecrypt($pue);echo 'private decrypt:' . $prd;?> 需要注意的是apache要支持openssl
