@rodoulv:
No my password will change depending on the user name.
password tomcat will have a different encrypted key wherein admin will have a different encrypted key.

Thanks!

Thanks a lot for the command! Your commadn works exactly fine except that it is changing the password for all the vlaues in the file.It should change valur onlt for the corresponding value, for which it is encrypted.

I tried this command, but it is not working..

Code:
perl -i.bak -pe's/(password=$ENV{i}").*?"/$1$ENV{en_passwd}"/' tomcat-users.xml

Any help would be appreciated.

Something like this:
Code:
perl -i.bak -p '-MDigest::SHA1 qw(sha1_base64)' -e'
  s/(password=")([^"]*)/$1.sha1_base64($2)/e' tomcat-users.xml

Sorry for quoting the question wrong.

I have an script which gives me encrypted key, which I store it in $en_passwd.

Your command works perfectly fine except that it is replacing all the passwords with the same value.
Code:
perl -i.bak -pe's/(password=").*?"/$1$ENV{en_passwd}"/' tomcat-users.xml

I have the following file:

Code:
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager"/>
  <role rolename="admin"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="role1" password="admin" roles="role1"/>
  <user username="both" password="mgr" roles="tomcat,role1"/>
  <user username="admin" password="testing" roles="admin,manager"/>
</tomcat-users>

When I run your command , the output is

Code:
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager"/>
  <role rolename="admin"/>
  <user username="tomcat" password="0567577538383" roles="tomcat"/>
  <user username="role1" password="0567577538383" roles="role1"/>
  <user username="both" password="0567577538383" roles="tomcat,role1"/>
  <user username="admin" password="0567577538383" roles="admin,manager"/>
</tomcat-users>

Since only tomcat is encrypted, i need to change only the value of password="tomcat".

I would run the command in a for loop for other passwords.

Please let me know if I have confused you.

Did you try the last script?
(without the rest of your code)

Code:
radoulov@linux-jgly:~/t> cat tomcat-users.xml
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager"/>
<role rolename="admin"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="role1" password="admin" roles="role1"/>
<user username="both" password="mgr" roles="tomcat,role1"/>
<user username="admin" password="testing" roles="admin,manager"/>
</tomcat-users>
radoulov@linux-jgly:~/t> perl -i.bak -p '-MDigest::SHA1 qw(sha1_base64)' -e'
>   s/(password=")([^"]*)/$1.sha1_base64($2)/e' tomcat-users.xml
radoulov@linux-jgly:~/t> cat tomcat-users.xml
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager"/>
<role rolename="admin"/>
<user username="tomcat" password="U2wLM5NFYWwbM8r0VEVNi4oZDWw" roles="tomcat"/>
<user username="role1" password="0DPiKuNIrrVmD8IUCuw1hQxNqZc" roles="role1"/>
<user username="both" password="W/z75CjM5CiVJ4eXhkPypZk0OKo" roles="tomcat,role1"/>
<user username="admin" password="3HJK8Y+91OWRifX+dopfgxFScFA" roles="admin,manager"/>
</tomcat-users>

OK,
you should install the module first.
Otherwise you can call your digest.sh from within your perl script,
could you give an example output of digest.sh, post the output of the following command:

Code:
/opt/coreservices/tomcat-5.5.9/bin/digest.sh -a sha tomcat
