Encryption and Digital Signature

[Former Member]

I am trying to understand the PGP Encryption along with Digital Signature.(Please help me, I am totally lost, thanks)

CASE 1

When I send an encrypted File to my Business Partner

-

---

gpg -e "Publickey1" "PrivateKey1" .

Note

Publickey1 is to encrypt the file (Its provided by my business partner)

here Privatekey1 is used to do the Digital signature (Created by our company)

CASE 2

When I receive an Encrypted file from my Business Partner

-

---

While doing the DECRYPTION

GPG -d "Privatekey1" "PublicKey2"

Privatekey1 : used to decrypt the file(in case 1 it was used to create the digital signature)

PublicKey2 : Used to verify the digital signature (Provided by our business partner)

Now my question here whether the Same key(PrivateKey1) is used for Digital Signature (while sending the file - Case 1) and also to do the Decryption (Case 2) ?

Whether my understanding is correct?

Thanks Kumar. I have enough documents with me, but unable to understand the Pseudocode what I have written.

Thanks for your helping hands.
