(Go) Generate RSA Public/Private Key Pair and Export to PEM

Go example code showing how to generate an RSA public/private key pair and export to PEM files.

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
    }

    // Keys are exported in XML format:
    publicKeyXml := rsa.ExportPublicKey()
    fmt.Println(*publicKeyXml)

    privateKeyXml := rsa.ExportPrivateKey()
    fmt.Println(*privateKeyXml)

    // Save the private key in PEM format:
    privKey := chilkat.NewPrivateKey()
    success = privKey.LoadXml(*privateKeyXml)
    success = privKey.SavePemFile("privateKey.pem")

    // Save the public key in PEM format:
    pubKey := chilkat.NewPublicKey()
    success = pubKey.LoadFromString(*publicKeyXml)
    success = pubKey.SavePemFile(false,"publicKey.pem")

    rsa.DisposeRsa()
    privKey.DisposePrivateKey()
    pubKey.DisposePublicKey()
