用openssl生成rsa密钥对(私钥/公钥):
openssl genrsa -out rsa_private_key.pem 2048 openssl rsa -pubout -in rsa_private_key.pem -out rsa_public_key.pem
RSA:
<?php header('Content-Type: text/plain;charset=utf-8'); $data = 'phpbest'; echo '原始内容: '.$data."\n"; openssl_public_encrypt($data, $encrypted, file_get_contents(dirname(__FILE__).'/rsa_public_key.pem')); echo '公钥加密: '.base64_encode($encrypted)."\n"; $encrypted = base64_decode('nMD7Yrx37U5AZRpXukingESUNYiSUHWThekrmRA0oD0='); openssl_private_decrypt($encrypted, $decrypted, file_get_contents(dirname(__FILE__).'/rsa_private_key.pem')); echo '私钥解密: '.$decrypted."\n"; ?>
