WebSuccinctly, the generic cryptographic hash algorithms are designed to be fast. Protecting a password requires a slow cryptographic hash algorithm. A fast cryptographic hash algorithm, iterated 2^16 times, becomes a slow cryptographic hash algorithm. Then add in other requirements such as salts, etc. – yfeldblum Jun 21, 2011 at 23:00 2 WebTools. In cryptography, a pepper is a secret added to an input such as a password during hashing with a cryptographic hash function. This value differs from a salt in that it is not …

In cryptography, a salt is random data that is used as an additional input to a one-way function that hashes data, a password or passphrase. Salts are used to safeguard passwords in storage. Historically, only the output from an invocation of a cryptographic hash function on the password was stored on a … See more Salt re-use Using the same salt for all passwords is dangerous because a precomputed table which simply accounts for the salt will render the salt useless. Generation of … See more 1970s–1980s Earlier versions of Unix used a password file /etc/passwd to store the hashes of salted passwords (passwords prefixed with two-character random … See more • Password cracking • Cryptographic nonce • Initialization vector • Padding See more To understand the difference between cracking a single password and a set of them, consider a file with users and their hashed passwords. Say the file is unsalted. Then an attacker could pick a string, call it attempt[0], and then compute hash(attempt[0]). A … See more It is common for a web application to store in a database the hash value of a user's password. Without a salt, a successful See more • Wille, Christoph (2004-01-05).

As such, frameworks such as OpenCL and CUDA can be leveraged in order to massively accelerate the operation of hash algorithms. Run oclHashcat with a decent graphics card and you can compute an excess of 10,000,000,000 MD5 hashes per second. WebFeb 22, 2024 · Cryptographic algorithms commonly use random number generators to produce the secret keys that encrypt and decrypt sensitive data. If the random number generation process is predictable, an attacker will be able to “guess” a user’s encryption key and decrypt the data.
