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.
The original creation of Gpg4win was initiated and funded by Germany's Federal Office for Information Security (BSI) in 2005, [2] [3] resulting in the release of Gpg4win 1.0.0 on 6 April 2006; [4] however Gpg4win and all included tools are free and open source software, and it is typically the non-proprietary option for privacy recommended [5] [6] to Windows users.
It also features an entropy gathering utility, coming in different versions for Unix-like and Windows machines. Usually multiple, stable branches of Libgcrypt are maintained in parallel; since 2022-03-28 this is the Libgrypt 1.10 branch as stable branch, plus the 1.8 branch as LTS ("long-term support") branch, which will be maintained at least ...
The current shipping versions are Symantec Encryption Desktop 10.3.0 (Windows and macOS platforms) and Symantec Encryption Server 3.3.2. Also available are PGP Command-Line, which enables command line-based encryption and signing of information for storage, transfer, and backup, as well as the PGP Support Package for BlackBerry which enables ...
In cryptography, the OpenPGP card [1] is an ISO/IEC 7816-4, -8 compatible smart card [2] that is integrated with many OpenPGP functions. Using this smart card, various cryptographic tasks (encryption, decryption, digital signing/verification, authentication etc.) can be performed.
Keys generated with GnuPG or GNUTLS are not affected as these programs used different methods to generate random numbers. Keys generated by non-Debian-based Linux distributions are also unaffected. The weak-key-generation vulnerability was promptly patched after it was reported, but any services still using keys that were generated by the old ...
