The PGP Desktop 9.x family includes PGP Desktop Email, PGP Whole Disk Encryption, and PGP NetShare. Additionally, a number of Desktop bundles are also available. Depending on the application, the products feature desktop e-mail, digital signatures, IM security, whole disk encryption, file, and folder security, encrypted self-extracting archives ...
Public key fingerprint. In public-key cryptography, a public key fingerprint is a short sequence of bytes used to identify a longer public key. Fingerprints are created by applying a cryptographic hash function to a public key. Since fingerprints are shorter than the keys they refer to, they can be used to simplify certain key management tasks.
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.
In October 2017, the ROCA vulnerability was announced that affects RSA keys generated by YubiKey 4 tokens, which often are used with PGP/GPG. Many published PGP keys were found to be susceptible. [35] Around June 2018, the SigSpoof attacks were announced. These allowed an attacker to convincingly spoof digital signatures. [36] [37]
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. The purpose of a PKI is to facilitate the secure electronic transfer of information for a range of network ...
List of file signatures. This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources. This is a list of file signatures, data used to identify or verify the content of a file. Such signatures are also known as magic numbers or Magic Bytes.
Keysigning is the process of digitally signing someone else's public key using one's own. A more correct term would be certificate signing, since the actual key material is not changed by the process of signing. However, in the PGP community it is customary not to distinguish in speaking between someone's key and certificate, and the term ...
Web of trust. In cryptography, a web of trust is a concept used in PGP, GnuPG, and other OpenPGP -compatible systems to establish the authenticity of the binding between a public key and its owner. Its decentralized trust model is an alternative to the centralized trust model of a public key infrastructure (PKI), which relies exclusively on a ...
