$ sudo xmlsec1 keys --privkey-pem userkey.pem keys2.xml

userkey.pem 파일을 이용해 keys2.xml 파일을 생성한다.

( 첨부된 userkey.pem 파일을 이용하면 되고, password는 hello이다.)

{keys2.xml}
<?xml version="1.0"?>

아래의 서명대상 파일을 다음과 같은 명령어를 이용해서명한다.

$ xmlsec1 sign --output dsig.xml --keys-file keys2.xml input.xml

{input.xml}
<?xml version='1.0'?>

서명이 정상적으로 완료되면 아래와 같은 서명파일을 얻을수있다.
{dsig.xml}

<?xml version="1.0"?>
