B4X Requires Chilkat v11.0.0+

Generate RSA Key and return Base64 PKCS8 Private Key

See more RSA Examples

Demonstrates how to generate a new 2048-bit RSA private key and returns the Base64 encoded PKCS8 representation of the private key. B4X

Dim success As Boolean = False

Dim rsa As ChilkatRsa
rsa.Initialize

'  Generate a 2048-bit key.  Chilkat RSA supports
'  key sizes ranging from 512 bits to 8192 bits.
Dim privKey As ChilkatPrivateKey
privKey.Initialize("privKey")
success = rsa.GenKey(2048, privKey)
If success = False Then
    Log(rsa.LastErrorText)
    Return
End If


'  Get the private key in PKCS8 Base64 format
Dim privKeyPkcs8Base64 As String = privKey.GetPkcs8ENC("base64")

'  The key in base64 format will start similar to this:
'  MIIEvAIBADANBgkqhkiG9w0BA...
