commons-codec-1.4.jar (in reality the latest release is not 1.4, but I don't care)
maven is:
<dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.4</version> </dependency>So I change implementation and I get this wonderful code:

In WebLogic there is a simple way of encrypting/decrypting passwords, but for fear of depending from the SerializedSystemIni.dat file I am afraid of using it.
Here the official documentation.
Anyway just run . ./setDomainEnv.sh and then "java weblogic.security.Encrypt mypwtoencrypt". To decrypt, since WebLogic doesn't provide a "weblogic.security.Decrypt" utility, follow these steps
In WLST, to decode you can do the following:
from javax.crypto import Cipher
from javax.crypto import SecretKey
from javax.crypto import SecretKeyFactory
from javax.crypto.spec import PBEKeySpec
from javax.crypto.spec import PBEParameterSpec
from org.apache.commons.codec.binary import Base64
def decode(encodedPassword):
SALT='\xde\x33\x10\x12\xde\x33\x10\x12'
key='yoursecretkeyhere'
keyFactory = SecretKeyFactory.getInstance("PBEWithMD5AndDES")
key = keyFactory.generateSecret(PBEKeySpec(key))
pbeCipher = Cipher.getInstance("PBEWithMD5AndDES")
pbeCipher.init(Cipher.DECRYPT_MODE, key, PBEParameterSpec(SALT, 20))
resultb=pbeCipher.doFinal(Base64.decodeBase64(encodedPassword))
print String(resultb, "utf-8")
