  Description     : Simple GTK+ software to generate OTPs (TOTP and HOTP)

  Highly secure and easy to use GTK+ software for two-factor
  authentication that supports both Time-based One-time Passwords
  (TOTP) and HMAC-Based One-Time Passwords (HOTP).
  .
  Features:
   - support both TOTP and HOTP
   - support setting custom digits (between 4 and 10 inclusive)
   - support setting a custom period (between 10 and 120 seconds inclusive)
   - support SHA1, SHA256 and SHA512 algorithms
   - support for Steam codes
   - import encrypted Authenticator Plus backup
   - import and export encrypted and/or plain andOTP backup
   - import and export plain FreeOTPPlus backup (key URI format only)
   - local database is encrypted using AES256-GCM
       * key is derived using PBKDF2 with SHA512 and 100k iterations
       * decrypted file is never saved (and hopefully never swapped) to disk.
         While the app is running, the decrypted content resides
         in a "secure memory" buffer allocated by Gcrypt
