machinekey 생성하는 validationkey 와 decryptionkey 값 생성하는 방법

public class KeyGenerator
{
    public string GenerateKey(int length, bool useUpperCase = true)
    {
        byte[] buffer = new byte[length];
        var randomNumberGenerator = new RNGCryptoServiceProvider();
        randomNumberGenerator.GetBytes(buffer);

        return ToHexString(buffer, true);
    }

    private static string ToHexString(byte[] bytes, bool useUpperCase = false)
    {
        var hex = string.Concat(bytes.Select(b => b.ToString(useUpperCase ? "X2" : "x2")));

        return hex;
    }
}

 

var generator = new KeyGenerator();

/* 512 bits = 64 bytes (512 / 8) */
string validationKey = generator.GenerateKey(64);

/* 256 bits = 32 bytes (256 / 8) */
string decryptionKey = generator.GenerateKey(32);

 

<machinekey compatibilitymode="Framework45"
            validation="HMACSHA256"
            validationkey="YOURVALIDATIONKEYHERE"
            decryption="AES"
            decryptionkey="YOURDECRYPTIONKEYHERE" />

샘플(모르겠으면 그냥 아래꺼 쓰심~)

<system.web>
    <machineKey validationKey="E4451576F51E0562D91A1748DF7AB3027FEF3C2CCAC46D756C833E1AF20C7BAEFFACF97C7081ADA4648918E0B56BF27D1699A6EB2D9B6967A562CAD14767F163"
                decryptionKey="6159C46C9E288028ED26F5A65CED7317A83CB3485DE8C592" validation="HMACSHA256" decryption="AES" />
