2. Password strength - Wikipedia

   en.wikipedia.org/wiki/Password_strength

   Password strength. Options menu of the random password generation tool in KeePass. Enabling more character subsets raises the strength of generated passwords a small amount, whereas increasing their length raises the strength a large amount. Password strength is a measure of the effectiveness of a password against guessing or brute-force attacks.

3. bcrypt - Wikipedia

   en.wikipedia.org/wiki/Bcrypt

   bcrypt is a password-hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher and presented at USENIX in 1999. [1] Besides incorporating a salt to protect against rainbow table attacks, bcrypt is an adaptive function: over time, the iteration count can be increased to make it slower, so it remains resistant to brute-force search attacks even with increasing ...

4. Cryptographic hash function - Wikipedia

   en.wikipedia.org/wiki/Cryptographic_hash_function

   A cryptographic hash function ( CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with a fixed size of bits) that has special properties desirable for a cryptographic application: [1] the probability of a particular. n {\displaystyle n} -bit output result ( hash value) for a random input string ("message") is.

6. Brute-force attack - Wikipedia

   en.wikipedia.org/wiki/Brute-force_attack

   Brute-force attacks work by calculating every possible combination that could make up a password and testing it to see if it is the correct password. As the password's length increases, the amount of time, on average, to find the correct password increases exponentially.

7. Symmetric-key algorithm - Wikipedia

   en.wikipedia.org/wiki/Symmetric-key_algorithm

   Symmetric -key algorithms [a] are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys. [1] The keys, in practice, represent a shared secret between two or more parties that can be used to maintain a private information ...
