PHP - RSA前端公钥加密后台秘钥解密

在开发中，前端向后台传输一些敏感数据时，如果不做一些数据的加密等，会以明文的形式进行传输，这样就把一些信息暴露到外面，下面要是一下通过RSA加密的方式进行传输:

1.首先前端加密需要用到js插件：jsencrypt.js下载地址

前端部分代码如下：【RSA公钥秘钥可通过在线工具获得】

//公钥var pubkey = -----BEGIN PUBLIC KEY-----;pubkey += MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDAbfx4VggVVpcfCjzQ+nEiJ2DL;pubkey += nRg3e2QdDf/m/qMvtqXi4xhwvbpHfaX46CzQznU8l9NJtF28pTSZSKnE/791MJfV;pubkey += nucVcJcxRAEcpPprb8X3hfdxKEEYjOPAuVseewmO5cM+x7zi9FWbZ89uOp5sxjMn;pubkey += lVjDaIczKTRx+7vn2wIDAQAB;pubkey += -----END PUBLIC KEY-----;//公钥加密var encrypt = new JSEncrypt();encrypt.setPublicKey(pubkey);var encrypted = encrypt.encrypt(JSON.stringify({"encrypt": "yes", "password": 123456}));console.log(encrypted);

2.php后端秘钥解密,部分代码如下:

//私密$pra_key = -----BEGIN RSA PRIVATE KEY-----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-----END RSA PRIVATE KEY-----;//获取加密后的密文$cryptograph = $_POST[cryptograph];//私钥解密openssl_private_decrypt(base64_decode($cryptograph),$decrypted,$pra_key);var_dump($decrypted);
