在 C# 中使用 RSA 算法对消息进行哈希和签名以实现紧凑框架
大家好,
我尝试使用 RSA 算法签署一条消息,我正在努力压缩框架,这是我的代码:
private void Signer_Click(object sender, EventArgs e)
{
///cle de string ver byte[]
string clePriveeFile = @"\Program Files\PrivateKey.pem";
StreamReader reader = new StreamReader(clePriveeFile);
string contenuKeyPrivate = reader.ReadToEnd();
byte[] keyByte = Certification.DecodeOpenSSLPrivateKey(contenuKeyPrivate);
string Data = "Salut tout le monde";
byte[] DataBytes = System.Text.Encoding.UTF8.GetBytes(Data);//.UTF7.GetBytes(Data);
//Hasher le message
SHA1Managed sha1 = new SHA1Managed();
byte[] hash = sha1.ComputeHash(DataBytes);
string hach = Convert.ToBase64String(hash);
RSACryptoServiceProvider Rsa = Certification.DecodeRSAPrivateKey(keyByte);
byte[] sign = Rsa.SignHash(hash, CryptoConfig.MapNameToOID("SHA1"));
string resultat = Convert.ToBase64String(sign);
this.label1.Text = this.resultat;
}
使用“DecodeOpenSSLPrivateKey”和“DecodeRSAPrivateKey”,它与此处使用的函数相同:http://www.jensign.com/opensslkey/index.html
我获得的哈希结果: hash = "I4t474liO6H+ p8SeDsoIkxmi8b0="
如果我使用 openSSL 命令做同样的事情: $ echo "Salut tout le monde"| openssl dgst -sha1 | openssl enc -base64
我得到这个: "NjFlOWI4Y2NjN2U2MzFkNTQwNTRmZjE1ZGUyYzk2MDczYTM2ZjRjZAo="
与我的符号结果相同,使用以下命令:
$ echo "Salut tout le monde"| openssl dgst -sha1 -sign PrivateKey.pem | openssl dgst -sha1 -sign PrivateKey.pem | openssl enc -base64
I Have a signature like this: "V6c6XNK7O8+IKKuGTGENdZwoWxhQLIEFHW7XSdoXzMAp1gLu8B5UxXi0lr6JhVDW6SI8p8PtlT+fxEoafY+ZCigIq4xW6e32f6hxYWeYi7silh44I1m7LF7JYR1lfcegnO0Cw+YPqLPRrZUbdcrvMo1ijUGH3SuK+iot2lait9s="
with My Code I obtain this:
result = "YlbnppFDP5ejdYOPoUI/1W6i+ClrKrxbIdA24IqllGDRWGBrWLtGwlfNkh4+B+gzcrX8HI7PkNP1Pq2ud1jE4EhfUVjBkZJwXj/ZYI3fPF41oiIMdF63lZiR/SEHQ5rMTbdsfQtkkBmFTr8udCJNnmnSimRQ458nZvIsYOUW6j4="
我找不到我的错误:(有人可以帮助我吗?
Hy everybody,
I try to sign one message with RSA algorithm, i'm working to compact Framwork this is my Code:
private void Signer_Click(object sender, EventArgs e)
{
///cle de string ver byte[]
string clePriveeFile = @"\Program Files\PrivateKey.pem";
StreamReader reader = new StreamReader(clePriveeFile);
string contenuKeyPrivate = reader.ReadToEnd();
byte[] keyByte = Certification.DecodeOpenSSLPrivateKey(contenuKeyPrivate);
string Data = "Salut tout le monde";
byte[] DataBytes = System.Text.Encoding.UTF8.GetBytes(Data);//.UTF7.GetBytes(Data);
//Hasher le message
SHA1Managed sha1 = new SHA1Managed();
byte[] hash = sha1.ComputeHash(DataBytes);
string hach = Convert.ToBase64String(hash);
RSACryptoServiceProvider Rsa = Certification.DecodeRSAPrivateKey(keyByte);
byte[] sign = Rsa.SignHash(hash, CryptoConfig.MapNameToOID("SHA1"));
string resultat = Convert.ToBase64String(sign);
this.label1.Text = this.resultat;
}
with 'DecodeOpenSSLPrivateKey' and 'DecodeRSAPrivateKey' it's the sames functions use here: http://www.jensign.com/opensslkey/index.html
for the result of my Hash i obtain: hash = "I4t474liO6H+p8SeDsoIkxmi8b0="
if i do same things with openSSL command: $ echo "Salut tout le monde"| openssl dgst -sha1 | openssl enc -base64
I obtain this: "NjFlOWI4Y2NjN2U2MzFkNTQwNTRmZjE1ZGUyYzk2MDczYTM2ZjRjZAo="
same with my sign result, with this command:
$ echo "Salut tout le monde"| openssl dgst -sha1 -sign PrivateKey.pem | openssl enc -base64
I Have a signature like this: "V6c6XNK7O8+IKKuGTGENdZwoWxhQLIEFHW7XSdoXzMAp1gLu8B5UxXi0lr6JhVDW6SI8p8PtlT+fxEoafY+ZCigIq4xW6e32f6hxYWeYi7silh44I1m7LF7JYR1lfcegnO0Cw+YPqLPRrZUbdcrvMo1ijUGH3SuK+iot2lait9s="
with My Code I obtain this:
result = "YlbnppFDP5ejdYOPoUI/1W6i+ClrKrxbIdA24IqllGDRWGBrWLtGwlfNkh4+B+gzcrX8HI7PkNP1Pq2ud1jE4EhfUVjBkZJwXj/ZYI3fPF41oiIMdF63lZiR/SEHQ5rMTbdsfQtkkBmFTr8udCJNnmnSimRQ458nZvIsYOUW6j4="
I can't to find my error :( can someone help me?

一个问题是
echo
输出包含换行符后缀。尝试散列“Salut tout le monde\n”。另一个是OpenSSL以十六进制编码格式输出SHA1摘要,因此将结果编码为Base64是没有意义的。
One problem is that the
echo
output contains a newline suffix. Try hashing "Salut tout le monde\n".Another is that OpenSSL outputs the SHA1 digest in hex-encoded format, so encoding the result in Base64 is meaningless.
或者在 openssl 命令行中,使用 echo|set /p=Salut tout le monde | openssl
/p 将抑制回车
or in openssl command line, use echo|set /p=Salut tout le monde | openssl
/p will suppress the carriage return
