Hash

Simple console cryptographic program.

Based on gmp-6.1.2 for RSA key generator, lua-5.3.4 for script executing and  zlib-1.2.11, bzip2-1.0.6,brotli-1.0.2  for compression. All libraries are linked statically
DOS/FreeDOS,WIN95,WIN98 versions are compiled by DJGPP(2.05) GCC5.1 on FreeDOS (Pent4). On DOS/FreeDOS version cwsdpmi must be used. LFN is supported.
WIN32 version is compiled by MinGW. No external cryptographic libraries (DLLs) are used.
Linux version is compiled by gcc. No external cryptographic libraries are used, no depencies.
Use hash -h for more information or read readme.txt.
Only single EXE file is used no instalation

Possibility to compress by zlib-1.2.11 (deflate), bzip2-1.0.6 or brotli-1.0.2 before encryption.

Example

Calculate SHA512 hash of all TXT files stored in directory C:\DOC and store result to file C:\HASH.SHA with verbose output to console
hash -v -mSHA512 -oC:\HASH.SHA C:\DOC\*.TXT

Check SHA512 hash of all files stored in file C:\HASH.SHA and store result to file C:\RESULT.TXT with verbose output to console
hash -v -mSHA512 -c -oC:\RESULT.TXT C:\HASH.SHA

TCP/IP <-> COM port/virtual COM port redirector.

WIN32 service redirects COM port or virtual COM port to local TCP/IP address and port. It is possible to redirect internet browser to local COM port as output from
embedded system.Compiled by MinGW or by VC. VCP is selected by VID, PID and version string. Localhost 127.0.0.1 can be used. See COM port redirector from wikipedia.
It is possible to use more redirectors on the same computer.

Example

Redirecting ST VCP to local computer port 8080
vcpredir -c"Vid_0483&Pid_5740/00000000050C" -p8080 -sAUTO
vcpredir -sSTART
vcpredir -sSTOP
vcpredir -sDELETE
