<?php /** * PKCS#8 Formatted RSA Key Handler * * PHP version 5 * * Used by PHP's openssl_public_encrypt() and openssl's rsautl (when -pubin is set) * * Processes keys with the following headers: * * -----BEGIN ENCRYPTED PRIVATE KEY----- * -----BEGIN PRIVATE KEY----- * -----BEGIN PUBLIC KEY----- * * Analogous to ssh-keygen's pkcs8 format (as specified by -m). Although PKCS8 * is specific to private keys it's basically creating a DER-encoded wrapper * for keys.
