Please use Maven as showed in the BUILD.
If it could not solve your problem, try to use *nix systems.

Please take a look at the following file: cpabe-api/src/main/java/co/junwei/cpabe/Cpabe.java in which you will find how to store the keys in a file. On Wed, Jun 27, 2018 at 1:49 PM, knagaraju799 <notifications@github.com> wrote:

Hello Sir, In your project is it possible to print public key and private key in human readable format ? because we need to know what is the public key and private key because I want to pass this to encryption algorithms so what I have to do ? please give me any suggestions !

First, please read this file cpabe-api/src/main/java/co/junwei/cpabe/Cpabe.java Try to understand how the keys are stored in the "unreadable" way. Then I hope you will figure out a way to store them in a readable way. On Wed, Jun 27, 2018 at 3:04 PM, knagaraju799 <notifications@github.com> wrote:

I stored keys in files , but I am unable to read that keys .. it stored some unreadable characters in that files . So , I am asking that how to store that keys in a file in readable format is it possible to store keys in readable format or not ? please don't mind sir because i am doing internship on this please help me .

Hello Sir, I am building the ABE without access policy in the encryption So I modified my code I got setup, keygen, encryption successfully but while I am doing decryption I am getting below error means I am getting negative numbers for len variable !! please kindly can you find where i am doing mistake ? while decryption . I tried but I am unable to solve that error . please help me .

Hello Sir, I am modifying your code . I am deleting access policy part from your code while doing encryption because I don't need of access policy in my project which I am doing by taking reference of your project . While decryption I noticed that two keys are coming different in the AES algorithm . please kindly help me on this project I cannot move forward in my project without doing encryption and decryption I clearly understood your code and I modified but still not getting may be I am doing wrong some where please find out where I am doing the mistake . I am also attaching modified code here In that code I commented lines which I don't require . you need to just run the file " DemoForCpabe.java " you will get output which I am printing lines for debugging purpose . So please ignore my mistakes because I am just testing your code and trying to modify that why I didn't following programming rules . I need your help please kindly give me reply . please tell me the mistake , and How to I decrypt the message without using access policy in encryption. Thank you .

Dear Sir
while debugging your code in eclipse, my console shows the following messages, but after the decryption the decrypted file is not created. Could you please let me know the issue.

thank you
