RSA Import Public Key from Certificate PEM

See more RSA Examples

Uses a certificate's public key for RSA encryption. The public key from the certificate .pem file is used. VB.NET

Dim success As Boolean = False

Dim cert As New Chilkat.Cert

success = cert.LoadFromFile("qa_data/pem/mf_public_rsa.pem")
If (success = False) Then
    Debug.WriteLine(cert.LastErrorText)
    Exit Sub
End If


Dim pubKey As New Chilkat.PublicKey
cert.GetPublicKey(pubKey)

Dim rsa As New Chilkat.Rsa
rsa.UsePublicKey(pubKey)

rsa.EncodingMode = "base64"
Dim encryptedStr As String = rsa.EncryptStringENC("hello",False)
Debug.WriteLine("encrypted string = " & encryptedStr)
