you can use split(',');

string mystring = "hello";
char h = mystring[0];      // h now contains the char 'h'

private key secured with a passphrase

• Generate the public and private key from the RSACryptoServiceProvider.
• Select a password and use PasswordDeriveBytes to generate a strong DES key.
• Using DESCryptoServiceProvider encrypt the private key of the RSA Key Pair with the bytes generated in step 2.
• Do what you want

• The simplest would be to generate some random bytes once and hard-code these into your application as the salt-bytes.  This however is not very secure or wise.
• The better way to accomplish this would be to write an algorithm (or find one) than generates some random bytes based on the password string, this would mean that the string changes each time the password changes but remains the same for the same password.
