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-----

Swift

func chilkatTest() {
    var success: Bool = false

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

    success = false

    let pem = CkoPem()!

    // Load a public key from a PEM file.
    // (Assume the PEM contains at least one public key..)
    success = pem.loadFile(path: "/Users/chilkat/testData/pem/myPublicKey.pem")
    if success != true {
        print("\(pem.lastErrorText!)")
        return
    }

    var i: Int
    var numPublicKeys: Int = pem.numPublicKeys.intValue
    if numPublicKeys == 0 {
        print("\(("Error: Expected the PEM to contain public keys.")!)")
        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:
        print("This is PKCS1 format:")
        pem.publicKeyFormat = "pkcs1"
        print("\(pem.to()!)")

        // Now PKCS8 PEM format:
        print("This is PKCS8 format:")
        pem.publicKeyFormat = "pkcs8"
        print("\(pem.to()!)")

    }
