Cryptographic software

Cryptomator is open source encryption software that provides encryption for cloud drives. It provides transparent, client-side encryption for personal cloud storage. Cryptomator encrypts each file separately and then allows the user to sync files with a cloud or local storage of choice. It is available for all major operating system including Android, iOS, Windows, Mac, Linux.

Hushmail is an encrypted proprietary web-based email service offering PGP-encrypted e-mail and vanity domain service. Hushmail uses OpenPGP standards. If public encryption keys are available to both recipient and sender (either both are Hushmail users or have uploaded PGP keys to the Hush keyserver), Hushmail can convey authenticated, encrypted messages in both directions.

' is a computer program that calculates and verifies SHA-1 hashes. It is commonly used to verify the integrity of files. It (or a variant) is installed by default on most Linux distributions. Typically distributed alongside are , , and , which use a specific SHA-2 hash function and ', which uses the BLAKE2 cryptographic hash function.

S/KEY is a one-time password system developed for authentication to Unix-like operating systems, especially from dumb terminals or untrusted public computers on which one does not want to type a long-term password. A user's real password is combined in an offline device with a short set of characters and a decrementing counter to form a single-use password. Because each password is only used once, they are useless to password sniffers.

strongSwan is a multiplatform IPsec implementation. The focus of the project is on authentication mechanisms using X.509 public key certificates and optional storage of private keys and certificates on smartcards through a PKCS#11 interface and on TPM 2.0.

KeeWeb is a free and open-source password manager compatible with KeePass, available as a web version and desktop apps. The underlying file format is KDBX (KeePass database file).

form of disk encryption where individual files or directories are encrypted by the file system itself

BestCrypt, developed by Jetico, is a commercial disk encryption app available for Windows, Linux, macOS and Android.

L3COS (Level 3 Consensus Operating System) is an algorithm for digitising processes based on Blockchain, which has a three-level structure and is distributed as Platform as a Service for state bodies and businesses. The algorithm is based on the blockchain, in which any decision made at any of the levels will become part of the common chain. The technology involves a three-level framework that provides national governments, businesses, and private individuals with the tools to create a digital economy that does not allow fraudulent activity, financial or otherwise.

Bitfrost is the security design specification for the OLPC XO, a low cost laptop intended for children in developing countries and developed by the One Laptop Per Child (OLPC) project. Bitfrost's main architect is Ivan Krstić. The first public specification was made available in February 2007.

Mitro was a password manager for individuals and teams that securely saved users' logins, and allowed users to log in and share access.

WinPT or Windows Privacy Tray is frontend to the GNU Privacy Guard (GnuPG) for the Windows platform. Released under GPL, it is compatible with OpenPGP compliant software.

SSLeay is an open-source SSL implementation. It was developed by Eric Andrew Young and Tim J. Hudson as an SSL 3.0 implementation using RC2 and RC4 encryption. The recommended pronunciation is to say each letter, S-S-L-E-A-Y; the "eay" comes from the initials of author Eric A. Young. SSLeay also included an implementation of DES from earlier work by Eric Young which was believed to be the first open-source implementation of DES. Development of SSLeay unofficially mostly ended, and volunteers forked the project under the OpenSSL banner around December 1998, when Hudson and Young both began work
