我正在尝试将以下用 C# 编写的密钥生成方法重写为其 Ruby 等效项:
private static byte[] CreateKey(string password, int length)
{
var salt = new byte[] { 0x01, 0x02, 0x23, 0x34, 0x37, 0x48, 0x24, 0x63, 0x99, 0x04 };
const int Iterations = 1000;
using (var rfc2898DeriveBytes = new Rfc2898DeriveBytes(password, salt, Iterations))
return rfc2898DeriveBytes.GetBytes(length);
}
我正在使用PBKDF2实现。这是我的 Ruby 代码:
def create_key password, length
salt_a = [0x01, 0x02, 0x23, 0x34, 0x37, 0x48, 0x24, 0x63, 0x99, 0x04]
salt = salt_a.pack('C*') # Think here there is something to change
iterations = 1000
derived_b = PBKDF2.new do |p|
p.password = password
p.salt = salt
p.iterations = iterations
p.key_length = length
p.hash_function = OpenSSL::Digest::SHA1
end
derived_b.bin_string # and here too
end
为了工作,这两种方法应该返回相同的输出。问题是我无法弄清楚如何做到这一点。PBKDF2 实现将盐作为字符串,但 C# 采用字节数组......我认为问题就在那里。
