Signature verification - How to perform SHA512withRSA algorithm signature in PHP?

Question

After searching, I only found the [SHA1withRSA][1] algorithm signature, but not the SHA512withRSA

Answer 1

function sign($data) {
    $certs = array();
    openssl_pkcs12_read(file_get_contents("你的.pfx文件路径"), $certs, "password"); //其中password为你的证书密码
    if(!$certs) return ;
    $signature = '';  
    openssl_sign($data, $signature, $certs['pkey'],OPENSSL_ALGO_SHA512);
    return base64_encode($signature); 
}

OopensSL_Sign 默认 Signature_alg 参数 是 OpenSSL_Algo_Sha1
Signature_alg 其他 参数

OpenSL_Algo_DSS1 (Integer)
OpenSL_SHA1 (Integer) )
openssl_algo_sha384 (Integer)
opensl_algo_sha512 (Integer)
opensl_algo_rmd160 (integer)
openssl_algo_md5 (integer )
　　OPENSSL_ALGO_MD4 (integer)
　　OPENSSL_ALGO_MD2 (integer)
