Description
The way public/private keys work, is a public key is used to encrypt data and only a private key is capable of decrypting it.
Public Key -> Encrypt.
Private Key -> Decrypt.
Example
This is a real example of public private key.
Create a public & private key.
Create a private key.
openssl genrsa -out mykey.pem 1024
Create a public key.
openssl rsa -in mykey.pem -pubout > mykey.pub
This will calculate the public key from the private key.
