OTPClient - Simple GTK+ software to generate OTPs (TOTP and
HOTP)

Passwords (HOTP).
OTPClient have the following features:
- Support both TOTP and HOTP.

inclusive).
- Support SHA1, SHA256 and SHA512 algorithms.
- Support for Steam codes.

- Import and export encrypted and/or plain andOTP backup.
- Import and export plain FreeOTPPlus backup (key URI format only).

the app is running, the decrypted content resides in a "secure
memory" buffer allocated by Gcrypt.
