PHP openssl_sign note #1
The list of Signature Algorithms (constants) is very limited! Fortunately the newer versions of php/openssl allow you to specify the signature algorithm as a string.
You can use the 'openssl_get_md_methods' method to get a list of digest methods. Only some of them may be used to sign with RSA private keys.
Those that can be used to sign with RSA private keys are: md4, md5, ripemd160, sha, sha1, sha224, sha256, sha384, sha512
Here's the modified Example #1 with SHA-512 hash:
$fp = fopen("/src/openssl-0.9.6/demos/sign/key.pem", "r");
$priv_key = fread($fp, 8192);
fclose($fp);
$pkeyid = openssl_get_privatekey($priv_key);
openssl_sign($data, $signature, $pkeyid, "sha512");
openssl_free_key($pkeyid);

This may help if you just want a real-simple private/public key pair:
$data = "Beeeeer is really good.. hic...";

PHP openssl_sign note #3
the fourth parameter 'signature_alg' to choose the signature algorithm can be one of:
OPENSSL_ALGO_SHA1
OPENSSL_ALGO_MD5
OPENSSL_ALGO_MD4
OPENSSL_ALGO_MD2

PHPOpenSSL - 函数关键词：微信支付&PaySignKey
微信支付现在分为v2版和v3版
号之前申请的为v2版，之后申请的为v3版。
V2版中的参数有AppIDAppSecret支付专用签名串PaySignKey商户号PartnerID初始密钥PartnerKey
并且包含一个证书文件: 安全证书
V3版中的参数有AppIDAppSecret商户号PartnerID初始密钥PartnerKey商户号MCHID申请编号商户平台登录帐号商户平台登录密码
包含5个证书文件（证书pkcs12格式、证书pem格式、证书密钥pem格式、CA证书， 安全证书）
如果收到的邮件中没有【支付专用签名串PaySignKey】，表示已经是V3版的微信支付，没有paySignKey这个参数了。

如果是在配置微信公众平台，那么检查开发者中心的url和key。如果是普通用户，关注了别人的微信，那么是别人微信的设置有问题。众帐号支付请求中用于加密的密钥Key，可验证商户唯一身份，PaySignKey对应于支付场景中的appKey值。审核通过后，在微信发送的邮件中查看。
