if (! openssl_sign($toSign, $signature, $cipher->key, OPENSSL_ALGO_MD5)) { openssl_error_string(); throw new Exception(); } 这里有几个关键点需要检查: $cipher->key:确保这个变量包含的是有效的私钥。如果 $cipher 对象是从 XMLSecurityKey 类创建的,并且你已经通过 loadKey() 方法加载...
最常用的算法之一是 SHA-256,还有 SHA-1、MD5、SHA-512 等等。 其次,我们需要在签名和验证时都使用同样的哈希算法。如果签名时使用了 SHA-256 算法,那么在验证时也必须使用 SHA-256 算法,否则签名验证将失败。 最后,哈希算法的安全性和性能需要综合考虑。通常情况下,越新的算法越安全(比如 SHA-3),但也有...

- `-pkeyopt digest:<digest_algorithm>`:可选参数,指定签名时使用的摘要算法,如`sha256`、`sha384`或`sha512`等,默认是`md5-sha1`(在某些版本中可能默认为`sha256`)。 - `-passin pass:password`:如果私钥文件被密码保护,需要提供此选项来输入密码。 二、实际操作步骤 以一个具体的例子来说明如何使用op...

The "mycert.pem" parameters as shown in the example above are not correct. You either have to pass a string containing the PEM encoded certificate or key, or the location of a file in file://path/to/file.pem notation. See the comments on the OpenSSL functions page (the page above thi...
