Private Key and Public Key in Digital Signatures
Private key is used for encryption:
- In digital signatures, the private key is used for encryption. The sender uses their private key to encrypt the message before sending it.
- The private key ensures that only the intended recipient, who possesses the corresponding public key, can decrypt and read the message.
Public key is used for decryption:
- On the other hand, the public key is used for decryption. The recipient uses their public key to decrypt the message that was encrypted with the sender's private key.
- This ensures that the message remains secure during transmission and can only be read by the intended recipient.
In summary, the private key is used for encryption to secure the message, while the public key is used for decryption to ensure only the intended recipient can read the message.
