HASHER2(1)						    BSD General Commands Manual 						HASHER2(1)

NAME
hasher2 -- block based hashing utility SYNOPSIS
hasher2 [-hBrv] [-a algorithm] [-b size] [-s string] [-f from] [-t to] [[file] ...] DESCRIPTION
This program is part of the radare project. Hasher allows you to calculate, check and show the hash values of each block of a target file. The block size is 32768 bytes by default. It's allowed to hash from stdin using '-' as a target file. You can hash big files by hashing each block and later determine what part of it has been modified. Useful for filesystem analysis. This command can be used to calculate hashes of a certain part of a file or a command line passed string. This is the command used by the '#' command of radare. -a algo Select an algorithm for the hashing. Valid values are md5, crc32 and sha1 -b block size Define the block size -B Show per-block hash -s string Hash this string instead of using the 'source' and 'hash-file' arguments. -f from Start hashing at given address -t to Stop hashing at given address -r Show output in radare commands -v Show version information -h Show usage help message.

NAME
ragg2 -- radare2 utility to run programs in exotic environments SYNOPSIS
ragg2 [-a arch] [-b bits] [-k kernel] [-f format] [-o file] [-i shellcode] [-I path] [-e encoder] [-B hexpairs] [-c k=v] [-C file] [-d off:dword] [-D off:qword] [-w off:hexpair] [-p padding] [-FOLsrxvh] DESCRIPTION
ragg2 is a frontend for r_egg, compile programs into tiny binaries for x86-32/64 and arm. This tool is experimental and it is a rewrite of the old rarc2 and rarc2-tool programs as a library and integrated with r_asm and r_bin. Programs generated by r_egg are relocatable and can be injected in a running process or on-disk binary file. ragg2-cc is another tool that comes with r2 and it is used to generate shellcodes from C code. The final code can be linked with rabin2 and it is relocatable, so it can be used to inject it on any remote process. ragg2-cc is conceptually based on shellforge4, but only linux/osx x86-32/64 platforms are supported. DIRECTIVES
The rr2 (ragg2) configuration file accepts the following directives, described as key=value entries and comments defined as lines starting with '#'. -a arch set architecture x86, arm -b bits 32 or 64 -k kernel windows, linux or osx -f format select binary format (pe, elf, mach0) -o file output file to write result of compilation -i shellcode specify shellcode name to be used (see -L) -e encoder specify encoder name to be used (see -L) -B hexpair specify shellcode as hexpairs -c k=v set configure option for the shellcode encoder. The argument must be key=value. -C file include contents of file -d off:dword Patch final buffer with given dword at specified offset -D off:qword Patch final buffer with given qword at specified offset -w off:hexpairs Patch final buffer with given hexpairs at specified offset -p padding Specify generic paddings with a format string. -F autodetect native file format (osx=mach0, linux=elf, ..) -O use default output file (filename without extension or a.out) -I path add include path -s show assembler code -x execute (just-in-time) EXAMPLE
$ cat hi.r /* hello world in r_egg */ write@syscall(4); exit@syscall(1); main@global(128) { .var0 = "hi!0; write(1,.var0, 4); exit(0); } $ ragg2 -O -F hi.r $ ./hi hi! $ cat hi.c main() { write(1, "Hello0, 6); exit(0); } $ ragg2 hi.c $ ./hi.c.bin Hello SEE ALSO
