What is privatekey in cryptography?

Private key is only known to the key owner. and it is kept secret.


What is the difference between private key and secret key as applied to coding theory and cryptology?

"Private key" in the context of cryptography refers to the the key generated for an asymmetric encryption algorithm which is retained by the owner while the companion "public key" is published for others to utilize for secure communications or authentication. The "private key" is not shared with anyone. A "secret key" in the context of cryptography refers to the single key generated for use in a symmetric encryption algorithm which is only shared between those between whom secure communication is desired. It is kept secret from all others. The secret key must be transmitted to or shared with all parties by a method outside the communications link it is intended to secure.


Asymmetric encryption involves?

The asymmetric key algorithms are used to create a mathematically related key pair: a secret private keyand a published public key.


What is the difference between Private key cryptography and public key cryptography?

Public key encryption refers to a type of cypher or code architecture known as public key cryptography that utilizes two keys, or a key pair), to encrypt and decrypt data. One of the two keys is a public key, which anyone can use to encrypt a message for the owner of that key. The encrypted message is sent and the recipient uses his or her private key to decrypt it. This is the basis of public and private key encryption.


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.


What is difference between secret key and public key encryption?

It depends on how you apply the term "secret key encryption". In one sense "Secret key encryption" refers to using symmetric keys - both parties have the key and must keep it secret in order to protect the confidentiality of the communication. Usually the process that was used to encrypt the original message can be decrypted by repeating the encryption process with the original secret key. This should provide for confidentiality, non-repudiation, and validation since only the holders of the shared secret key should be able to successfully encrypt and decrypt the messages. In contrast to the symmetric key encryption, Public Key encryption uses two keys in the encryption/decryption process. Anything encrypted with one key can be decrypted with the other key. The "public key" is published for everyone to access. The "private key" is kept by the owner and not made available to the world. The encryption of the original message using one key can be "undone" only by using the other key. Using the public key on a message already encrypted with the public key only results in an even more jumbled and unintelligible mess. The end result is that is someone encrypts a message with their private key, only their public key can be used to decrypt it, thus verifying the source of the message. Any message encrypted using the public key can only be decrypted with the private key, thus providing confidentiality. If two users want to use asymmetric encryption to communicate securely, they can do it this way: Alice encrypts a message to Bob using Bob's public key. Only Bob can decrypt it and read it (using his private key). He can then send a return email to Alice using Alice's public key that only Alice can decrypt and read (using her own private key). If they wish, they can use this method to agree upon and exchange a shared symmetric key than can be used for further secure communications. Several automatic secure protocols use exactly this method or a variation of it. The alternate meaning is to make "secret key" synonymous with the "private key" of asymmetric encryption. In this case there is really no difference between secret key and public key encryption except for which key of the public/private key pair is being used and who can read it.

What are the roles of Public and Private Key?

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
