Generate an ECDSA Key

See more ECC Examples

Demonstrates how to generate an ECDSA key. VB.NET

Dim success As Boolean = False

' This requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' Create a Fortuna PRNG and seed it with system entropy.
' This will be our source of random data for generating the ECC private key.
Dim fortuna As New Chilkat.Prng
Dim entropy As String = fortuna.GetEntropy(32,"base64")
success = fortuna.AddEntropy(entropy,"base64")

Dim ecc As New Chilkat.Ecc

' Generate a random ECC private key on the secp256r1 curve.
' Chilkat also supports other curves, such as secp384r1, secp521r1, and secp256k1.

Dim privKey As New Chilkat.PrivateKey
success = ecc.GenKey("secp256r1",fortuna,privKey)
If (success = False) Then
    Debug.WriteLine(ecc.LastErrorText)
    Exit Sub
End If


Debug.WriteLine(privKey.GetXml())

' Save the private key to PKCS8 encrypted PEM
' (The private key can be saved in a variety of different formats. See the online reference documentation.)
success = privKey.SavePkcs8EncryptedPemFile("pemPassword","myPemFiles/eccKey123.pem")
If (success <> True) Then
    Debug.WriteLine(privKey.LastErrorText)
End If


Debug.WriteLine("finished.")
