在发送到 PHP 应用程序之前,我尝试在 javascript 中对消息进行签名。PHP 应用程序必须检查签名以确保它不是假的。
在 javascript 中,我使用 cryptico.js。
这是给消息签名的js函数
var sign = function(passphrase, text) {
signingkey = cryptico.generateRSAKey(passphrase, 2048);
signString = cryptico.b16to64(signingkey.signString(text, "sha256"));
return signString;
}
这是获取公钥的函数:
var getPublicKey = function(passphrase) {
var rsaKey = cryptico.generateRSAKey(passphrase, 2048);
return = cryptico.publicKeyString(rsaKey);
}
例如,对于消息“message”和密码短语“test2”,公钥和签名是

我在问我如何在php中验证它?
我尝试了类似的东西:
$rsa = new Crypt_RSA();
$rsa->loadKey('qH/J3/gvF/h5U02uPyC9Qzn/hHEV5DzB9nFfqk5zbQqHdInVe4sfL+npa+4fjLGrBU30Iuvcr+o9paEjzpH5dY48cq6JHqz1RyJ0CQIc2Jr5+sS4eL1ZIjxWlyN1pKMR+4aE2rlDAad56Ad1cytiaHuVvyK/gdtbKiuGroSQhJ1EVfZ60m3NIqnqmpi5Zdsnmzny4VH/d66BcGXxGaGaUaqFn0WTypuwIMZMMtzZEK7peKoaW4H4rfkfdrKcD8AaT+z9v5lLGkTl0NcZZ4LN9sSUzsHNfyAFK6cSXo/73z0tDAlGb5K+yWV6UHoYW1rcoIsxlNRZM6/6FYgMXbbfow=='); // public key
echo $rsa->verify('message', 'XbF4O6v6oadEQGtdpQ7d54Q2JB9/ZEXEUH3S1FMn4E/PSqk7HLXjG4tNfuiUBa5eS8kYV49gwC8Yr+mn6YUAHt+K9lHPSsmltWoiHNOaas4aqai9nlyeft4TYYhP+GYbQfw+3n2TcO39s6M0vw0m0a8AX9JfF02JwCUhP4bu4dzG6Bl5dj000TbUkric14Jyurp8OHmmMvKW62TvXPhNOW39+wS1Qkfn9Bxmzi8UEVSVe3wP45JWZNgmgeGnpubDhD05FJEDErfVtZ/DRKD81q5YRd4X4cCkeDPDcJLgKW1jkCsA7yBqESXPDSkkrVUM06A9qMFUwk4mRI88fZ8ryQ==') ? 'verified' : 'unverified';
我认为签名和/或公钥的格式不适合 php。任何想法?
先感谢您,
[编辑] 我不确定签名是否正确。如果我使用 js 函数cryptico.b64to16(signature)
,签名将类似于:

我不确定 $rsa->verify 的参数键的格式。我尝试添加前缀 ssh-rsa。但效果并不好。
所以我尝试了 to 签名格式和 to 密钥。消息每次都“未经验证”
