LIBTOMCRYPT RSA DIGITAL SIGNATURES HOW-TO This how-to describes how to implement RSA digital signatures using LibTomCrypt (and LibTomMath) on Windows and macOS. GETTING STARTED 1. Get LibTomMath and LibTomCrypt git clone https://github.com/TaleTN/libtommath.git git clone https://github.com/TaleTN/libtomcrypt.git 2. Remove unused source files (optional) perl remove_unused.pl --force 3. Build LibTomMath and LibTomCrypt [n]make [-f makefile.msvc] 4. Generate public/private key pair [n]make [-f makefile.msvc] key 5. Run sign and verify examples [n]make [-f makefile.msvc] test 6. Have fun! FILES IN THIS DISTRIBUTION dertoh.cpp - Utility that converts DER to C/C++ header file format, so you can directly include the public key in a C/C++ source file. dertopem.sh - Bash script that uses OpenSSL to convert the public and private key pair from DER to PEM file format. error.h - Helper routines for rsa_make_key.cpp, rsa_sign.cpp, and rsa_verify.cpp. LICENSE - License, duh! makefile - GCC/Clang makefile. makefile.msvc - Microsoft C/C++ makefile. README - <-- You are here. remove_unused.pl - Perl script that removes all unused LibTomMath and LibTomCrypt files. rsa_make_key.cpp - Example that generates a public and private key pair. rsa_sign.cpp - Example that signs a message. rsa_verify.cpp - Example that verifies a signature.
