Using Codeigniter Encryption Library outisde CI

Hi and gooday,

I would like to ask help from all of you guys. I have a Pure Php code project which needs decryption. The Encrypted data is in the database which was encrypted by a CI. Now my project is created from Pure Php (no framework used) and now I need to decrypt the data using CIencryption library. I tried the normal decryption but the results are either none or far from the original data before encryption.

Is there a way wherein I can use the CI encryption library outside A CI folder?

Thanks.
