A piece of hardware or software used to authorise access to a service.
A form of authentication based on tokens, most commonly received and sent through different network protocols. Entirely based on inherence and ownership factors, making passwordless more secure than traditional username/password logins.
In according of service requested, you can choose 2 types of application token
- Sandbox: for develop scope, with tiny area, restricted data, no usage reports and poor service responses
- Production: for production scope, without restriction, with usage reports and best service responses
The bundle identifier is used to uniquely identify an application. The bundle identifier is defined by the app author. It is used to recognize updates to some system and app. After you define the bundle identifier for an app, you cannot modify it.
Most encryption technologies are based around a system of “keys” that allow information to be encoded and then decoded. The terms “private key”, “public key”, and “host key” are used extensively in Secure Shell communication and can be confusing to those who are new to the terminology. This topic hopes to define and clarify these terms and their use.
- Private Key: A private key is one of two keys used in public-key encryption (the other being a public key). The user keeps the private key secret and uses it to encrypt outgoing messages and decrypt incoming messages. The permissions for the private key should be set so that only the owner has read/write access. This is especially important if the key does not have a passphrase.
- Public Key: A public key is one of two keys used in public-key encryption (the other being a private key). The user releases a copy of this key to the public to allow anyone to use it for encrypting messages to be sent to the user and for decrypting messages received from the user.
- Public-Key Encryption: A scheme using an asymmetric algorithm to create a pair of keys for encryption: a public key encrypts data, and a corresponding private key decrypts it. In some situations, such as digital signatures, the process is reversed: the sender uses a private key to create a unique number that can be read by anyone who has the corresponding public key. The agreement of the public and private keys verifies that the message is truly from the sender.
- Public-Key Authentication: In public-key authentication , public-private key pairs are used to identify a user to an SSH2 server . A user creates both a public and private key, and then transfers a copy of the public key to an SSH2 server to which the user wants secure access. The private key is kept on the user’s local machine and is used to verify the identity of the user when the user attempts to connect to the SSH2 server. The public and private keys must be correct for the server to allow the connection .
