Python wrapper for the otpnitro crypto library
OTP Nitro is a secure One Time Pad implementation to use on computers or as assistant on manual operations.
Generate OTP pages on the “TST” book:
C:\> .\otpnitro.exe -g -r TST OTP Nitro 0.1 ------------- [I] Generating OTP: TST. OK
C:\> otpnitro.exe -e -s CPX -r TST -m "ESTO ES UNA PRUEBA" OTP Nitro 0.1 ------------- [I] Encrypted msg: TST DE CPX 11 = RHJQG AKZQV RUMKV IYHJY YQYVT =
C:\> otpnitro.exe -d -p 11 -s CPX -r TST -m "RHJQG AKZQV RUMKV IYHJY YQYVT" OTP Nitro 0.1 ------------- [I] Decrypted msg: TST DE CPX 11 = ESTO ES UNA PRUEBA =
Decrypt formated message:
C:\> otpnitro.exe -d -f "TST DE CPX 11 = RHJQG AKZQV RUMKV IYHJY YQYVT =" OTP Nitro 0.1 ------------- [I] Decrypted msg: TST DE CPX 11 = ESTO ES UNA PRUEBA =
Burn a page:
C:\> otpnitro.exe -b -p 11 -r TST OTP Nitro 0.1 ------------- [I] Burn page 11. OK
OTPNITRO is a secure One Time Pad implementation to use on computers or as assistant on manual operation.
In this chapter we describe the basic concepts to use in this app.
The cipher data is stored on books, every book have “pages” where the data is generated. The books usually have very short names, from 3 to 5 characters.
The pages store the cipher to crypt and decrypt, every page is unique and after use it you must burn the used page.
- From field
The recipient is anyone who have the same book than you used to crypt the message and you must identify yourself as sender in the from field. The IDs usually have very short names, from 3 to 5 characters.
- Formatted message
To have a send/receive standar format, please use this one:
<BOOK> DE <FROM> <PAGE> = <MESSAGE> =
TST DE CPX 2 = QSZBO IGFIY NVTVY BFXCB KROAP =
In this chapter we describe the basic operations.
- Generate a book
- The first operation is generate a book, to do this, please use the menu: Books -> Generate Book or press CTRL + G keys.
- To crypt a message you must provide a valid book in the selector, an arbitrary ID in the form field and a message unformated to crypt. The page will be selected automatically. Later you must use the menu: Crypto -> Crypt or press CTRL + E keys.
- To decrypt a message you can provide a formatted message, in this case you only must select the “Formatted msg” option. If you dont have the format, you can enter all fields manually. Later you must use the menu: Crypto -> Decrypt or press CTRL + D keys.
- Burn page
- It is recommended to burn the page after use, but if you want to do this manually (or later) you can use the menu: Crypto -> Burn page or press CTRL + B keys.
- Refresh books
- If you modify or delete any book in the filesystem you must refresh the books in the app. To do that you can use the menu: Crypto -> Refresh books or press CTRL + R keys.
In this chapter we describe internal operations, know bugs or missing features.
- The settings/config file must be located on %APPDATA%/.otpnitro/otpnitro.ini or $HOME/.otpnitro/otpnitro.ini
- Book storing
- By default the books are stored on %APPDATA%/.otpnitro/PAGES or $HOME/.otpnitro/PAGES (this can be changed in the config file)
- Max pages parameter
- Is the number of pages generated for book. (this value limits the number of messages to be crypted on a book)
- Max chars parameter
- Is the number of characters generated for page. (this value limits the number of text to be crypted)
- Project URL
- For more information, updates, etc. you can visit the project homepage.

CLI compile guide
Generic / Debian:
CXX=clang++ gmake freebsd-cli
GUI compile guide
Next you must put the otpnitro path in the package textbox.
Click on the output mode button.
Fill all settings as in the image.
Next select “Build methods” menu
Again fill all options and add the otpnitro path to “lib directories”
Ok, you can build all now pressing the F7 key.
CXX=clang++ gmake freebsd
OTP Nitro supports bindings to other languages using SWIG
make python-otpnitro ( Install the .deb or .tzx package )
>> import otpnitro >> page = otpnitro.Page() >> print page.list()
