Keyring (cryptography)
In cryptography, a keyring stores known encryption keys (and, in some cases, passwords). For example, GNU Privacy Guard makes use of keyrings. See also * Java KeyStore A Java KeyStore (JKS) is a repository of security certificates either authorization certificates or public key certificates plus corresponding private keys, used for instance in TLS encryption.

Cryptography
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security (data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synony ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Encryption Key
A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on the security of the key being maintained. A key’s security strength is dependent on its algorithm, the size of the key, the generation of the key, and the process of key exchange. Scope The key is what is used to encrypt data from plaintext to ciphertext. There are different methods for utilizing keys and encryption. Symmetric cryptography Symmetric cryptography refers to the practice of the same key being used for both encryption and decryption. Asymmetric cryptography Asymmetric cryptography has separate keys for encrypting and decrypting. These keys are known as the public and private keys, respectively. Purpose Since the key ...

GNU Privacy Guard
GNU Privacy Guard (GnuPG or GPG) is a free-software replacement for Symantec's PGP cryptographic software suite. The software is compliant with RFC 4880, the IETF standards-track specification of OpenPGP. Modern versions of PGP are interoperable with GnuPG and other OpenPGP-compliant systems. GnuPG is part of the GNU Project and received major funding from the German government in 1999. Overview GnuPG is a hybrid-encryption software program because it uses a combination of conventional symmetric-key cryptography for speed, and public-key cryptography for ease of secure key exchange, typically by using the recipient's public key to encrypt a session key which is used only once. This mode of operation is part of the OpenPGP standard and has been part of PGP from its first version. The GnuPG 1.x series uses an integrated cryptographic library, while the GnuPG 2.x series replaces this with Libgcrypt. GnuPG encrypts messages using asymmetric key pairs individ ...

Java KeyStore
A Java KeyStore (JKS) is a repository of security certificates either authorization certificates or public key certificates plus corresponding private keys, used for instance in TLS encryption. In IBM WebSphere Application Server and Oracle WebLogic Server, a file with extension ''jks'' serves as a keystore. The Java Development Kit maintains a CA keystore file named ''cacerts'' in folder ''jre/lib/security''. JDKs provide a tool named ''keytool'' to manipulate the keystore. ''keytool'' has no functionality to extract the private key out of the keystore, but this is possible with third-party tools like jksExportKey, CERTivity, Portecle and KeyStore Explorer. See also * Java Secure Socket Extension *Keyring (cryptography) *Public key infrastructure A public key infrastructure (PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption.
