Key in byte[] format
Example
C#
Copy
// Test vectors from [RFC7914]
// scrypt (P="password", S="NaCl", N=1024, r=8, p=16, dkLen=64)
int dkLen = 64;
byte[] pwd = System.Text.Encoding.Default.GetBytes("password");
byte[] salt = System.Text.Encoding.Default.GetBytes("NaCl");
byte[] key = Pbe.Scrypt(dkLen, pwd, salt, 1024, 8, 16);
Debug.Assert(key.Length > 0, "ERROR with Pbe.Scrypt");
Console.WriteLine("dk={0}", key.ToHex());
