(Excel) Convert DSA PEM Private Key to DERConverts a DSA private key from PEM format to DER. The first part of the example will convert an unencrypted PEM to DER, then 2nd part will convert an encrypted PEM to unencrypted DER.
' This example requires the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. Dim dsa As Chilkat.Dsa Set dsa = Chilkat.NewDsa ' Load a PEM private key. pemPrivateKey = dsa.LoadText("dsa_priv.pem") ' Import the unencrypted PEM into the DSA object. success = dsa.FromPem(pemPrivateKey) If (success <> True) Then Debug.Print dsa.LastErrorText Exit Sub End If ' Write it out as a DER file: success = dsa.ToDerFile("dsa_priv.der") If (success <> True) Then Debug.Print dsa.LastErrorText Exit Sub End If ' Load an encrypted PEM private key. pemPrivateKey = dsa.LoadText("dsa_privEncrypted.pem") ' Import the encrypted PEM into the DSA object. success = dsa.FromEncryptedPem("myPassword",pemPrivateKey) If (success <> True) Then Debug.Print dsa.LastErrorText Exit Sub End If ' Write it out as an unencrypted DER file: success = dsa.ToDerFile("dsa_priv2.der") If (success <> True) Then Debug.Print dsa.LastErrorText Exit Sub End If Debug.Print "Finished!" |
