What ? : web based ssh key generator

Published on 14/07/2008 in Uncategorized. 7 Comments

This is amazing !! euuh total verrückt meine ich.

Es geht doch gar nicht, dass man sich seine (private) Schlüssel generieren lässt.

Naja manche machen es !! [http://sshkeygen.com/]

Man sollte denken, niemand könnte je so unglaublich dämlich sein, sich einen Krypto-Schlüssel von jemand anderem generieren zu lassen, denn das heißt ja nicht ohne Grund “private key”. Aber offensichtlich gibt es für die menschliche Dummheit keine Obergrenze.

	ushort crc = 0xFFFF;

	{
		byte dat = data[r];
		for (int j = 0; j < 8; j++ )
		{
		if (((dat ^ crc) & 0x01) != 0 )
		{
			crc >>= 1;
			crc ^= 0x8008; // CRC_POLYNOM;
		}
		else { crc >= 1; }
		dat >>= 1;
		}
	}
        crc = (ushort)(crc ^ 0xFFFF);

   return new byte[] { (byte)(crc >> 8), (byte)(crc & 0x00ff) };
