go-clamav is go wrapper for [libclamav](https://docs.clamav.net/manual/Development/libclamav.html)
|
|
|
|
## Environment
|
|
### Ubuntu
|
|
|
|
```bash
|
|
apt-get update && apt-get install -y \
|
|
`# install tools` \
|
|
gcc make pkg-config python3 python3-pip python3-pytest valgrind \
|
|
`# install clamav dependencies` \
|
|
check libbz2-dev libcurl4-openssl-dev libjson-c-dev libmilter-dev \
|
|
libncurses5-dev libpcre2-dev libssl-dev libxml2-dev zlib1g-dev
|
|
|
|
python3 -m pip install --user cmake / apt-get install cmake
|
|
```
|
|
|
|
Download the source from the clamav [downloads page](https://www.clamav.net/downloads)

## Quick Start
|
|
### Dynamic linking
|
|
```bash
|
|
$ cd example && cat main.go
|
|
```
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
|
|
clamav "github.com/ca110us/go-clamav"
|
|
)
|
|
|
|
func main() {
|
|
// new clamav instance
|
|
c := new(clamav.Clamav)
|
|
err := c.Init(clamav.SCAN_OPTIONS{
|
|
General: 0,
|
|
Parse: clamav.CL_SCAN_PARSE_ARCHIVE | clamav.CL_SCAN_PARSE_ELF,
|
|
Heuristic: 0,
|
|
Mail: 0,
|
|
Dev: 0,
|
|
})
|
|
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
|
|
// free clamav memory
|
|
defer c.Free()
|
|
|
|
// load db
|
|
signo, err := c.LoadDB("./db", uint(clamav.CL_DB_DIRECTORY))
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
fmt.Println("db load succeed:", signo)
|
|
|
|
// compile engine
|
|
err = c.CompileEngine()
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
|
|
c.EngineSetNum(clamav.CL_ENGINE_MAX_SCANSIZE, 1024*1024*40)
|
|
c.EngineSetNum(clamav.CL_ENGINE_MAX_SCANTIME, 9000)
|
|
// fmt.Println(c.EngineGetNum(clamav.CL_ENGINE_MAX_SCANSIZE))
|
|
|
|
// scan
|
|
scanned, virusName, ret := c.ScanFile("./test_file/nmap")
|
|
fmt.Println(scanned, virusName, ret)
|
|
}
|
|
```
|
|
|
|
```bash
|
|
$ CGO_LDFLAGS="-L/usr/local/lib -lclamav" go run main.go
|
|
|
|
db load succeed: 9263
|
|
209 YARA.Unix_Packer_UpxDetail.UNOFFICIAL Virus(es) detected
|
|
```
|
|
|
|
If the `libclamav.so` file is not found, try it:
|
|
|
|
```bash
|
|
$ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib CGO_LDFLAGS="-L/usr/local/lib -lclamav" go run main.go
|
|
|
|
db load succeed: 9263
|
|
209 YARA.Unix_Packer_UpxDetail.UNOFFICIAL Virus(es) detected
|
|
```
|
|
|
|
### Static build
|
|
```bash
|
|
sudo bash ./prepare.sh
|
|
|
|
export CGO_CFLAGS="-g -Wall -I./clamav-mussels-cookbook/mussels/install/include"
|
|
export CGO_LDFLAGS="-L./clamav-mussels-cookbook/mussels/install/lib -lclamav_static -lbz2_static -lclammspack_static -lclamunrar_iface_static -lclamunrar_static -lcrypto -ljson-c -lpcre2-8 -lpcre2-posix -lssl -lxml2 -lz -lm -ldl -lstdc++"
|
|
|
|
CGO_ENABLED=1 go build --ldflags '--extldflags "-static -fpic"' main.go
|
|
```
