Decrypt2

See more MIME Examples

Demonstrates how to decrypt MIME using a certificate and private key where the certificate and its corresponding private key are stored in separate files -- a .cer for the certificate, and a .pem for the private key. Go

    success := false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    mime := chilkat.NewMime()

    // Load the certificate from a .cer file.
    cert := chilkat.NewCert()
    success = cert.LoadFromFile("aaworkarea/myCert.cer")
    if success == false {
        fmt.Println(cert.LastErrorText())
        mime.DisposeMime()
        cert.DisposeCert()
        return
    }

    // Load the private key from an encrypted PEM file.
    // (A private key can be loaded from other file formats also..)
    privKey := chilkat.NewPrivateKey()
    success = privKey.LoadEncryptedPemFile("aaworkarea/myPrivateKey.pem","myPassword")
    if success == false {
        fmt.Println(privKey.LastErrorText())
        mime.DisposeMime()
        cert.DisposeCert()
        privKey.DisposePrivateKey()
        return

        mime.DisposeMime()
        cert.DisposeCert()
        privKey.DisposePrivateKey()
        return
    }
