Hi, All!

Following code works on Windows XP SP2/SP1 (eng, IE 6.0.2900.2180), but does
not work on Windows 2000 SP4 (eng, IE 5.00.3700.1000). On both system .NET
Framework 1.1.4 is installed.

CspParameters csp = new CspParameters();

csp.KeyContainerName = "OC_AS_asax_1_11";

csp.ProviderType=1;

csp.ProviderName="Microsoft Base Cryptographic Provider v1.0";

csp.Flags = CspProviderFlags.UseMachineKeyStore;

RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(1024,csp);

byte[] buf = new byte[58];

byte[] ebuf=rsa.Encrypt(buf, false);

"Bad key" exception throws when Encrypt is called. It works only when I
replace "Microsoft Base Cryptographic Provider v1.0" with "Microsoft
Enhanced Cryptographic Provider v1.0". Why? Does anybody know what is the
problem?
