stoken 0.90-1 (amd64 binary) in ubuntu xenial

 stoken is a software token which generates one-time passwords compatible
 with RSA SecurID 128-bit (AES) tokens. SecurID tokens are commonly
 used to authenticate end users to protected network resources and VPNs,
 as OTPs provide greater resistance to many attacks associated with static
 passwords.
 .
 stoken aims to provide a Linux-friendly, free software alternative to the
 proprietary RSA SecurID Software Authenticators.
 .
 This package contains standalone command-line and GTK+ GUI programs that
 allow for importing token seeds, generating tokencodes, and various
 utility/testing functions.
