Hi , 
We are trying to Decrypt the file from SFTP file path using File Listner and there are no OTB functions availble , hence we write a custom java code which is working fine in 24.2 but not in 25.1 

If any one achived in 25.1 please do let us know the steps, I have attached the sample java code which is working in 24.2 
All the PGP jars ar einplace and there are no compile time issues 

Error Iam geteting 

File decryption failed, error generated:Invalid UTF-8 input and teh ObjectFactory object is getting empty

Thanks in Advance.
