A user's private key is kept private and known only to the user. The user's public key is made available to others to use. The private key can be used to encrypt a signature that can be verified by anyone with the public key. Or the public key can be used to encrypt information that can only be decrypted by the possessor of the private key

What is a characteristic of public key cryptography?
If data is encrypted with the public key, only the private key can decrypt itAnswer Explanation: Public key encryption uses an asymmetric algorithm, which uses a public key and private key combination for the encryption and decryption process. If data is encrypted with the public key, only the private key can decrypt the data. The public key cannot decrypt a message that was encrypted with the public key. Alternatively, if data is encrypted with the private key, only the public key can decrypt the data.
Private key encryption safer than public key?
No, Public key cryptography is safer than Private key Cryptography. In public key cryptography only only one part of key is visible to others.
With what do we associate the term public key and private key?
The public key is associated with a key that is used in an entire program while a private key is only used within a function.
To accurately transmit an electronic message the sender needs to know one code and the receiver needs to know a different one. what online security measure is being used?
It is the Public Key Encryption. A user using the Public Key Encryption has to have both a private key and a public key to send a secured message. The private key is used to unlock both a private and a public key encryption. A public key cannot unlock a private encryption.
In asymmetric encryption Both the sender and receiver have a private key and a shared private key?
No, both sender and receiver have a private key and a public key. It works like this: if you encrypt something with one key, you need the other to decrypt it. You give everyone a copy of your public key. When they want to send you something encrypted, they use your public key to send it. Only your private key can decrypt it, so no one else can read it. You don't give out your private key.
What are characteristics of public key cryptography?
If data is encrypted with public key, only private key can decrypt it. AGN
Difference between public and private key?
Examples of a private organisation: McDonalds, Topshop, The Trafford Centre. It is an organisation that is owned privatly by someone and who has to sell a product or provide a service to make their money. Examples of a public organisation: The police, The Fire service. It is an organisation owned by the government to help the public, it is not owned privately.
How many keys are utilized in asymmetric encryption?
Asymmetric encryption uses at least 2 keys - hence the asymmetry. The keys for encryption and decryption are not the same, so they are not "symmetric". Usually only 2 keys are used - a public key and a private key. The public key is published to a key registry or sent separately to those the key-pair owner wants to communicate with. The private key is retained by the owner. Messages encrypted with the private key can only be decrypted using the public key. If the source of the public key is trusted, this provides some proof of the source of the message. Messages encrypted with the public key can only be decrypted using the private key - so only the owner of the private key should be able to decrypt messages encrypted with their own private key.
Utilizing Public Key Encryption How would John and Jim send an encrypted message between parties?
John would use Jim's public key to encrypt and Jim would use his private key to decrypt.Public Key Cryptography (Asymmetric encryption)An algorithm where data encrypted with a public key can only be decrypted by the matching private key. Vice versa is true, what is encrypted with a private key can only be decrypted with a public key.
What are the types of cryptography?

Roles of the government in a mixed economy?
To protect the public and to preserve private enterprise.
