Hi Nitin,

Thirdy party vendor able to decrypt the files which we have encrypted but we are not able to decrypt the files which was encrypted by the vendor.

Hello Mahesh,

Can you please tell me, how many key pairs you are using for this activity? I mean you are using one key pair for the encryption done by PI and decryption done at 3rd party.

And another key pair for encryption done at 3rd party and decryption done at PI end?

I would suggest you to do the following way -

1. Generate 2 key pairs i.e, 2 public and 2 Private key.

2. Use Public key of 1st pair to encrypt the message at PI end and give Private key of 1st pair to 3rd party to decrypt the message - This would be for outbound Scenario

3. Ask 3rd party to use public key of 2nd pair to encrypt the message and use the Private key of 2nd pair to decrypt the message from PI end.

You can do this with single pair, but it will lead to slightest of confusion, hence suggested to use 2 key pairs.

Please let me know if you need more help on this.
