An One Time Password (rfc2289) implementation for the Android.
It is used for logging into a (OTP enabled) system from an untrusted terminal by generating a password that is only valid for one login.
Supports SHA1 and MD5.Option to store passphrase and challange (encrypted with IMEI (device) and IMSI (sim) via AES-256)
Very convenient, if you change almost all the default settings :-)
