Key types affected include SSH keys, OpenVPN keys, DNSSEC keys, key material for use in X.509 certificates and session keys used in SSL/TLS connections. 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.
Password is the master password from which a derived key is generated; Salt is a sequence of bits, known as a cryptographic salt; c is the number of iterations desired; dkLen is the desired bit-length of the derived key; DK is the generated derived key; Each hLen-bit block T i of derived key DK, is computed as follows (with + marking string ...
The first public release of Crack was version 2.7a, which was posted to the Usenet newsgroups alt.sources and alt.security on 15 July 1991. Crack v3.2a+fcrypt, posted to comp.sources.misc on 23 August 1991, introduced an optimised version of the Unix crypt() function but was still only really a faster version of what was already available in other packages.
Security researchers have cracked a password to recover over $3 million of bitcoin that had been stuck in a crypto wallet for 11 years.. Electrical engineer Joe Grand, who goes by the handle ...
A new vulnerability in certain old Bitcoin wallets means it's open season for hackers. ... that created cryptographic keys that weren’t random enough. Instead of crafting electronic keys that ...
In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2]
This sequence is used as an encryption key at one end of communication, and as a decryption key at the other. One can implement a key generator in a system that aims to generate, distribute, and authenticate [4] keys in a way that without the private key, one cannot access the information in the public end.

Such a failure in random number generation caused users of Android Bitcoin Wallet to lose their funds in August 2013. [4] To ensure that is unique for each message, one may bypass random number generation completely and generate deterministic signatures by deriving from both the message and the private key. [5]
