def self.bytes_to_hex(bytes)
  bytes.map { |byte| byte.to_s(16).rjust(2, "0") }.join
end

.encrypt(data_str) ⇒ Object

返回 32 位小写十六进制 MD5。原来的逐字节位运算 hack 在 Ruby 下会得到 nil， 且被 rescue 吞掉返回空串，故直接使用 Digest::MD5.hexdigest。

def self.encrypt(data_str)
  Digest::MD5.hexdigest(data_str.encode("UTF-8"))

def self.hash_mac(data, secret)
  raise ArgumentError, "secret is required for HMAC" if secret.nil? || secret.to_s.empty?

  kd_mac = OpenSSL::HMAC.digest(OpenSSL::Digest.new("sha256"), secret, data)
  hex_string = bytes_to_hex(kd_mac.bytes)
  Base64.strict_encode64(hex_string)
