(Go) Generate RSA Key and Export to Encrypted PEM

Go sample showing how to generate an RSA key and export to encrypted PEM.

Chilkat Go Downloads Go Package for Windows, MacOS, Linux, Alpine Linux, Solaris

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

    rsa := chilkat.NewRsa()

    // Generate a 1024-bit key.  Chilkat RSA supports
    // key sizes ranging from 512 bits to 4096 bits.
    success := rsa.GenerateKey(1024)
    if success != true {
        fmt.Println(rsa.LastErrorText())
        rsa.DisposeRsa()
        return
    }

    // Get the private key as unencrypted XML:
    keyXml := rsa.ExportPrivateKey()
    fmt.Println(*keyXml)

    // To encrypt the key -- meaning to get the key in
    // an encrypted PEM format -- load it into a PrivateKey object,
    // and then export to encrypted PEM:
    privKey := chilkat.NewPrivateKey()

    success = privKey.LoadXml(*keyXml)
    if success != true {
        fmt.Println(privKey.LastErrorText())
        rsa.DisposeRsa()
        privKey.DisposePrivateKey()
        return
    }

    var strEncPem *string = new(string)

    strEncPem = privKey.GetPkcs8EncryptedPem("myPassword")

    // You now have the private key in an encrypted format,
    // which may be (for example) saved to a database

    privKey.DisposePrivateKey()
