(Go) Get an Ed25519 Key in Raw Hex Format

Demonstrates how to get the private and public key parts of an Ed25519 key in lowercase hex formmat.

Note: This example requires Chilkat v9.5.0.83 or greater.

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.

    // Load an Ed25519 key from some format..
    privKey := chilkat.NewPrivateKey()

    // This loads an Ed25519 key from an unencrypted PEM file (no password required).
    success := privKey.LoadAnyFormatFile("qa_data/eddsa/ed25519.pem","")
    if success == false {
        fmt.Println(privKey.LastErrorText())
        privKey.DisposePrivateKey()
        return
    }

    // The key type should be "ed25519" to indicate an Ed25519 key.
    fmt.Println("key type = ", privKey.KeyType())

    // What is the size of the private key in bits?  (should always be 256 bits for Ed25519)
    fmt.Println("size in bits = ", privKey.BitLength())

    // Get the private and public key parts in raw hex format:
    sbPubKeyHex := chilkat.NewStringBuilder()
    privKeyHex := privKey.GetRawHex(sbPubKeyHex)

    // We should have a 32-byte private key (a 64 character hex string).
    fmt.Println("private key = ", *privKeyHex)

    // We should have a 32-byte public key (a 64 character hex string).
    fmt.Println("public key = ", *sbPubKeyHex.GetAsString())

    // Sample output:
    // key type = ed25519
    // size in bits = 256
    // private key = d4ee72dbf913584ad5b6d8f1f769f8ad3afe7c28cbf1d4fbe097a88f44755842
    // public key = 19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1
