Write PKCS1 or PKCS8 Public Key PEM

See more PEM Examples

Demonstrates how to write either PKCS1 or PKCS8 format PEM files. PKCS1 public keys have this PEM format:

-----BEGIN RSA PUBLIC KEY-----
BASE64 ENCODED DATA
-----END RSA PUBLIC KEY-----

PKCS8 public keys have this PEM format:

-----BEGIN PUBLIC KEY-----
BASE64 ENCODED DATA
-----END PUBLIC KEY-----

Go

    success := false

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

    success = false

    pem := chilkat.NewPem()

    // Load a public key from a PEM file.
    // (Assume the PEM contains at least one public key..)
    success = pem.LoadPemFile("/Users/chilkat/testData/pem/myPublicKey.pem")
    if success != true {
        fmt.Println(pem.LastErrorText())
        pem.DisposePem()
        return
    }

    var i int
    numPublicKeys := pem.NumPublicKeys()
    if numPublicKeys == 0 {
        fmt.Println(("Error: Expected the PEM to contain public keys."))
        pem.DisposePem()
        return
    }

    // Get each public key as PEM, first in PKCS1 format, then in PKCS8.
    for i = 1; i <= numPublicKeys; i++ {

        // First output to PKCS1 PEM format:
        fmt.Println("This is PKCS1 format:")
        pem.SetPublicKeyFormat("pkcs1")
        fmt.Println(*pem.ToPem())

        // Now PKCS8 PEM format:
        fmt.Println("This is PKCS8 format:")
        pem.SetPublicKeyFormat("pkcs8")
        fmt.Println(*pem.ToPem())

    }


    pem.DisposePem()
