Niyebe, simple and secure pseudo-random string generator for the forgetful.

Generate random string with 46 characters:

$ niyebe 46      
FYiM6%F[4"76.Td4<[xH3m2QEk-Pvoi%16H7H9mqEzp3a^

Generate random digits only

$ niyebe 20 --digits
16270019754304914183

Generate random ASCII characters in lowercase (a-z)

$ niyebe 20 --lowercase
befkycnjqdxmwwvxeykv

Generate random ASCII characters in uppercase (A-Z)

$ niyebe 20 --uppercase
VFBSOUMBDKAOBRLZGVGK

Generate random ASCII special characters

$ niyebe 20 --symbols
`;?_.#/?`<\+?_||&`(=

• generate secure random strings based on given length
• using OpenSSL under the hood

Niyebe is using OpenSSL's RAND_bytes function to generate secure random string. See code in action here.

• Operating System:
  • Ubuntu, Debian (64-bit)
  • Windows 10 or 11 (64-bit)

• MSYS2 (UCRT64)

  • CMake - mingw-w64-ucrt-x86_64-cmake
  • MinGW-w64 - mingw-w64-ucrt-x86_64-gcc
  • OpenSSL - mingw-w64-ucrt-x86_64-openssl

  CMake, MinGW and OpenSSL can be installed inside MSYS2 via pacman

• GNU Compiler Collection
• Git
• CMake
• libssl-dev

Using cmake via MSYS2 (UCRT64)

Debug build

> cmake.exe -G "MinGW Makefiles" -DCMAKE_CXX_COMPILER=x86_64-w64-mingw32-g++ -DCMAKE_BUILD_TYPE=Debug -B build/debug
> cmake.exe --build build/debug
> .\build\debug\bin\niyebe.exe 

Using mingw32-make

> mingw32-make.exe
> niyebe.exe

Debug build

$ cmake -DCMAKE_CXX_COMPILER=g++ -DCMAKE_BUILD_TYPE=Debug -B build/debug
$ cmake --build build/debug
$ ./build/debug/bin/niyebe

$ make
$ ./niyebe

1. Create Release build

   > cmake.exe -G "MinGW Makefiles" \ 
       -DCMAKE_CXX_COMPILER=x86_64-w64-mingw32-g++ \
       -DCMAKE_BUILD_TYPE=Release \
       -DCMAKE_PREFIX_PATH=C:/msys64/ucrt64 \
       -B build/release
   > cmake.exe --build build/release
   > .\build\release\bin\niyebe.exe 
   

2. Install in C:/Niyebe directory

   > cmake --install build/release --config Release --prefix C:/Niyebe
   

3. Run niyebe.exe

   > C:/Niyebe/bin/niyebe.exe -v
   

1. Create Release build

   $ cmake -DCMAKE_CXX_COMPILER=g++ -DCMAKE_BUILD_TYPE=Release -B build/release
   $ cmake --build build/release
   $ ./build/release/bin/niyebe
   

2. Install

   $ sudo cmake --install build/release --prefix /opt/niyebe
   

   This will install/copy the compiled executable to /opt/niyebe.

3. Run niyebe

   $ /opt/niyebe/bin/niyebe -v
   

To add niyebe to PATH

$ echo "export PATH="$PATH:/opt/niyebe"" >> ~/.bashrc
$ source ~/.bashrc
