Recover Weblogic Server Admin password

Thanks to Marcin @eMarcel.com I managed to retrieve the Weblogic Admin password.

For archival and with some changes for eBS 12.2, the steps:

create a python script with vi (e.g. decrypt.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)

set the environment with

. $EBS_DOMAIN_HOME/bin/setDomainEnv.sh

Get the encrypted password:

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

Run the python script with:

java weblogic.WLST decrypt.py

The same script can also be used for other passwords in $EBS_DOMAIN_HOME/config/……
