  2. Bitwarden - Wikipedia

    en.wikipedia.org/wiki/Bitwarden

    Bitwarden is a free/freemium open-source password management service that stores sensitive information such as website credentials in an encrypted vault. The platform offers a variety of client applications including a web interface, desktop applications, browser extensions, mobile apps, and a command-line interface.

  3. Random number generation - Wikipedia

    en.wikipedia.org/wiki/Random_number_generation

    Random number generation is a process by which, often by means of a random number generator (RNG), a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated. This means that the particular outcome sequence will contain some patterns detectable in hindsight but unpredictable to foresight.

  4. One-time password - Wikipedia

    en.wikipedia.org/wiki/One-time_password

    RSA Security's SecurID is one example of a time-synchronization type of token, along with HID Global's solutions. Like all tokens, these may be lost, damaged, or stolen; additionally, there is an inconvenience as batteries die, especially for tokens without a recharging facility or with a non-replaceable battery.

  5. Key (cryptography) - Wikipedia

    en.wikipedia.org/wiki/Key_(cryptography)

    Key vs password. A password is a memorized series of characters including letters, digits, and other special symbols that are used to verify identity. It is often produced by a human user or a password management software to protect personal and sensitive information or generate cryptographic keys.

  6. Cryptographic hash function - Wikipedia

    en.wikipedia.org/wiki/Cryptographic_hash_function

    A cryptographic hash function (CHF) is a mathematical algorithm that maps data of an arbitrary size (often called the "message") to a bit array of a fixed size (the "hash value", "hash", or "message digest").

  8. Security token - Wikipedia

    en.wikipedia.org/wiki/Security_token

    Usually most tokens store a cryptographic hash of the password so that if the token is compromised, the password is still protected. [citation needed] Programmable tokens. Programmable tokens are marketed as "drop-in" replacement of mobile applications such as Google Authenticator (miniOTP). They can be used as mobile app replacement, as well ...

  9. SHA-2 - Wikipedia

    en.wikipedia.org/wiki/SHA-2

    SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher.
