Get the Admin account password in Weblogic Systems

Recently I had the entrust to get the admin account password of weblogic, so after a little bit searching in oracle documentation and web I used the following code:

The steps:

1.- Build script get_password.py

from weblogic.security.internal import *
from weblogic.security.internal.encryption import *
encryptionService = SerializedSystemIni.getEncryptionService(".")
clearOrEncryptService = ClearOrEncryptedService(encryptionService)

# Take encrypt password from user
pwd = raw_input("Paste encrypted password ({AES}fk9EK...): ")

# Delete unnecessary escape characters
preppwd = pwd.replace("\\", "")

# Display password
print "Decrypted string is: " + clearOrEncryptService.decrypt(preppwd)

2.- Set the environmental variables

sh $DOMAIN_HOME/bin/setDomainEnv.sh | source $DOMAIN_HOME/bin/setDomainEnv.sh

3.- Get the username and password

grep username $DOMAIN_HOME/servers/AdminServer/security/boot.properties | sed -e "s/^username=\(.*\)/\1/"
|
grep password $DOMAIN_HOME/servers/AdminServer/security/boot.properties | sed -e "s/^password=\(.*\)/\1/"

4.- cd $DOMAIN_HOME/security

java weblogic.WLST get_password.py


bash-3.2$ java weblogic.WLST get_password.py

Initializing WebLogic Scripting Tool (WLST) ...

Update:

If your environment doesn't recognize your wlst command do the following:

 sh /$ENV/fmw/product/111/soa_111/common/bin/wlst.sh get_password.py

You must be located in $DOMAIN_HOME/security.
