# This scripts installs OpenSSL of a given version and SHA256. If the version is
# not specified, DEFAULT_OPENSSL_VERSION is used; similarly the digest is by
# default DEFAULT_OPENSSL_SHA256.
#
# NOTEs:
#   * If not running on Kokoro, this script will do nothing.
#   * This script MUST be sourced to update the environment of the calling
#     script.
#   * If a custom version is passed, the corresponding digest should be passed
#     too.
#
# Usage:
#   source ./kokoro/testutils/install_openssl.sh [version] [sha256]
