Simple example:
#include<stdio.h>#include<strings.h>#include<errno.h>#include"libinjection.h"#include"libinjection_sqli.h"intmain(intargc, constchar*argv[])
{
structlibinjection_sqli_statestate;
intissqli;
constchar*input=argv[1];
size_tslen=strlen(input);
/* in real-world, you would url-decode the input, etc */libinjection_sqli_init(&state, input, slen, FLAG_NONE);
issqli=libinjection_is_sqli(&state);
if (issqli) {
fprintf(stderr, "sqli detected with fingerprint of '%s'\n", state.fingerprint);
}
returnissqli;
}$ gcc -Wall -Wextra examples.c libinjection_sqli.c
$ ./a.out "-1' and 1=1 union/* foo */select load_file('/etc/passwd')--"
sqli detected with fingerprint of 's&1UE'

See CHANGELOG for details.
Versions are listed as "major.minor.point"
Major are significant changes to the API and/or fingerprint format. Applications will need recompiling and/or refactoring.
Minor are C code changes. These may include
- logical change to detect or suppress
- optimization changes
- code refactoring
Point releases are purely data changes. These may be safely applied.
The continuous integration results at https://travis-ci.org/client9/libinjection tests the following:
- build and unit-tests under GCC
- build and unit-tests under Clang
- static analysis using clang static analyzer
- static analysis using cppcheck
- checks for memory errors using valgrind
- code coverage online using coveralls.io
