RSA Sign utf-8 Byte Representation of String

See more RSA Examples

Demontstrates how to sign the utf-8 byte representation of a string. Go

    success := false

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

    // Load an RSA private key for signing.
    privKey := chilkat.NewPrivateKey()
    success = privKey.LoadEncryptedPemFile("qa_data/pem/rsa_passwd.pem","passwd")
    if success == false {
        fmt.Println(privKey.LastErrorText())
        privKey.DisposePrivateKey()
        return
    }

    rsa := chilkat.NewRsa()
    success = rsa.UsePrivateKey(privKey)
    if success == false {
        fmt.Println(rsa.LastErrorText())
        privKey.DisposePrivateKey()
        rsa.DisposeRsa()
        return
    }

    originalData := "This is the string to be hashed an RSA signed."

    // Indicate that we want the utf-8 byte representation of the string to be signed
    rsa.SetCharset("utf-8")

    // We want the RSA signature in base64 format
    rsa.SetEncodingMode("base64")

    sigBase64 := rsa.SignStringENC(originalData,"sha256")
    fmt.Println(*sigBase64)

    privKey.DisposePrivateKey()
    rsa.DisposeRsa()
