I need to use MD5 to generate a hash of a string. It needs to be
compatible with the MD5 implementation in PHP.

public string ComputeMD5(string plain)
{
 MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
 byte[] bMD5Hash = Encoding.ASCII.GetBytes(plain);
 return Encoding.ASCII.GetString(md5.ComputeHash(bMD5Hash));
 //return Convert.ToBase64String(md5.ComputeHash(bMD5Hash));
}

With PHP I get:
md5('test1test1test1test1test1test1') = '0b2fc97f2a37500552d805c4727295a8'

In .NET I get:
ComputeMD5('test1test1test1test1test1test1') = ' /I*7PRXDrr('
ComputeMD5('test1test1test1test1test1test1') = 'Cy/Jfyo3UAVS2AXEcnKVqA=='
(base64)

Am I doing it wrong or are the PHP and .NET implementations not compatible?

Thanks in advance,
Casper Hornstrup
