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. It allows secure storage of secret key material; all versions of ...
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 ...
Here hash functions are defined as taking an arbitrary length message and producing a fixed size output that is virtually impossible to use for recreating the original message. Implementation MD5
The encryption and decryption schema of Zend Framework, to generate encryption and authentication keys. [16] Cisco IOS and IOS XE Type 4 password hashes [17] Firefox Sync for client-side password stretching [18]
The contents of the encrypted device are arbitrary, and therefore any filesystem can be encrypted, including swap partitions. [2] There is an unencrypted header at the beginning of an encrypted volume, which allows up to 8 (LUKS1) or 32 (LUKS2) encryption keys to be stored along with encryption parameters such as cipher type and key size.

Pidgin (software), has a plugin that allows for AES Encryption; Javascrypt [8] Free open-source text encryption tool runs entirely in web browser, send encrypted text over insecure e-mail or fax machine. PyEyeCrypt [9] Free open-source text encryption tool/GUI with user-selectable AES encryption methods and PBKDF2 iterations. Signal Protocol
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 until 2024-12-31.
The development of the Signal Protocol was started by Trevor Perrin and Moxie Marlinspike (Open Whisper Systems) in 2013. The first version of the protocol, TextSecure v1, was based on Off-the-record messaging (OTR). [7] [8] On 24 February 2014, Open Whisper Systems introduced TextSecure v2, [9] which migrated to the Axolotl Ratchet.
