md5加密节点js和magento不匹配..

Question

I have created login service in both magento and node js. In magento if customer is registered with password, the password is encrypted with md5 salt key value. If i am using crypto node js module to decrypt the magento password it is throwing error.

Error: Unknown cipher

Only if i decrypt the magento password i can verify my login password matches and i can proceed. I tried to encrypt my node js login password but the password doesnot matches..
