Useful to load shellcodes .It Fl K Show randomart key asciiart for values or hexpairs .It Fl s Convert from hex string to character (rax2 \-s 43 4a 50) .It Fl S Convert from character to hex string (rax2 \-S C J P) .It Fl n Show hexpairs from integer value .It Fl N Show hexadecimal C string from integer value .It Fl u Convert given value to human readable units format .It Fl v Show program version .It Fl x Convert a string into a hash .It Fl h Show usage help message .El .Sh USAGE .Pp Force output mode (numeric base) .Pp =f floating point =2 binary =3 ternary =8 octal =10 decimal =16 hexadecimal .Pp Available variable types are: .Pp int \-> hex rax2 10 hex \-> int rax2 0xa \-int \-> hex rax2 \-77 \-hex \-> int rax2 0xffffffb3 int \-> bin rax2 b30 bin \-> int rax2 1010d float \-> hex rax2 3.33f hex \-> float rax2 Fx40551ed8 oct \-> hex rax2 35o hex \-> oct rax2 Ox12 (O is a letter) bin \-> hex rax2 1100011b hex \-> bin rax2 Bx63 .Pp With no arguments, rax2 reads values from stdin. You can pass one or more values as arguments. .Pp $ rax2 33 0x41 0101b 0x21 65 0x5 .Pp You can do 'unpack' hexpair encoded strings easily. .Pp $ rax2 \-s 41 42 43 ABC .Pp And it supports some math operations. .Pp $ rax2 0x5*101b+5 30 .Pp It is a very useful tool for scripting, so you can read floating point values, or get the integer offset of a jump or a stack delta when analyzing programs. .Pp .Sh SEE ALSO .Pp .Xr radare2(1) , .Xr rahash2(1) , .Xr rafind2(1) , .Xr rabin2(1) , .Xr radiff2(1) , .Xr ragg2(1) , .Xr rarun2(1) , .Xr rasm2(1) .Sh AUTHORS .Pp Written by pancake .
