AWS CloudFormation is a service provided by Amazon Web Services (AWS) that enables users to model and manage infrastructure resources in an automated and secure manner. [1] Using CloudFormation, developers can define and provision AWS infrastructure resources using a JSON - or YAML -formatted infrastructure as code template.
Example of a web form with name-value pairs. A name–value pair, also called an attribute–value pair, key–value pair, or field–value pair, is a fundamental data representation in computing systems and applications. Designers often desire an open-ended data structure that allows for future extension without modifying existing code or data.
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1] [2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.
Key exchange (also key establishment) is a method in cryptography by which cryptographic keys are exchanged between two parties, allowing use of a cryptographic algorithm. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key. After obtaining an authentic copy of each other's ...
Secure Sockets Layer (SSL) uses Diffie–Hellman key exchange if the client does not have a public-private key pair and a published certificate in the public key infrastructure, and Public Key Cryptography if the user does have both the keys and the credential. Key distribution is an important issue in wireless sensor network (WSN) design ...
Requests changing the passphrase of a private key file instead of creating a new private key. -t Specifies the type of key to create (e.g., rsa). -o Use the new OpenSSH format. -q quiets ssh-keygen. It is used by the /etc/rc file while creating a new key. -N Provides a new Passphrase. -B Dumps the key's fingerprint in Bubble Babble format. -l
Houston Texans wide receiver Tank Dell is out for the rest of the season after suffering a dislocated knee, torn ACL and other damage, Texans head coach DeMeco Ryans said to reporters Monday.
Re-Key, Re-Key-Key-Pair: creating a new key that can replace an existing key. There are also attributes that can be used to have the server automatically rotate keys after a given period or number of uses. The Name is moved to the new key and is normally used to retrieve a key for protection operations such as encrypt and sign.
