Body
@CodesInChaos was right, it was an endianness problem. I have used a function "OS2IP" taken from <a href="http://www.codeproject.com/Articles/421656/RSA-Library-with-Private-Key-Encryption-in-Csharp" rel="nofollow">here</a>. Just used it to generate the BigInteger from the byte array. <pre><code>Dim P As Numerics.BigInteger = cripto.OS2IP(Convert.FromBase64String("gbb1FjTyN ... hs="), false) </code></pre> Then I had to reverse the generated byte array: <pre><code>Dim ResultBytes As Byte() = cripto.RSA_Decrypt(P, Q, D, Data).Reverse.ToArray </code></pre> And the function that corrects the endianness: <pre><code>''' <summary> ''' Converts a byte array to a non-negative integer. ''' </summary> ''' <param name="data">The number in the form of a byte array.</param> ''' <param name="isLittleEndian">Endianness of the byte array.</param> ''' <returns>An non-negative integer from the byte array of the specified endianness.</returns> Public Shared Function OS2IP(data As Byte(), isLittleEndian As Boolean) As Numerics.BigInteger Dim bi As Numerics.BigInteger = 0 If isLittleEndian Then For i As Integer = 0 To data.Length - 1 bi += Numerics.BigInteger.Pow(256, i) * data(i) Next Else For i As Integer = 1 To data.Length bi += Numerics.BigInteger.Pow(256, i - 1) * data(data.Length - i) Next End If Return bi End Function </code></pre> With that change, the result is now correct. Now I will look at the timing-attack issue :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
