Функция tls.X509KeyPair

Функция tls.X509KeyPair загружает и парсит сертификат X.509 и соответствующий ему приватный ключ из байтовых срезов. В первый параметр мы передаем байтовый срез с PEM-кодированным сертификатом, во второй параметр мы передаем байтовый срез с PEM-кодированным приватным ключом. Функция возвращает структуру tls.Certificate и ошибку, если парсинг не удался.

Синтаксис

tls.X509KeyPair(certPEM, keyPEM []byte) (tls.Certificate, error)

Пример с самоподписанным сертификатом

Давайте создадим пару сертификата и ключа в памяти с помощью функции X509KeyPair:

package main import ( "crypto/tls" "fmt" "log" ) func main() { // PEM-кодированный сертификат (пример) certPEM := []byte(`-----BEGIN CERTIFICATE-----
